The code in +`DCAFitterN.h` matches the O2 convention above. In the rest of this document +`R_i` is always the O2 local-to-global rotation. + +## 2. Weighted N-prong vertex fit + +For track `i`, let the current point in its local frame be + +```text +p_i = (x_i, y_i, z_i)^T . +``` + +Let `B_i` be the inverse covariance, or information matrix, for this local +point. The fitted vertex `V` is in the global frame. Its representation in +track `i`'s local frame is `R_i^T V`, so the residual is + +```text +Delta_i = p_i - R_i^T V . +``` + +The weighted objective is + +```text +chi2 = 1/2 sum_i Delta_i^T B_i Delta_i . +``` + +For fixed track points, differentiating with respect to `V` gives + +```text +A V = sum_i R_i B_i p_i +``` + +where + +```text +A = sum_i R_i B_i R_i^T . +``` + +Therefore + +```text +V = A^{-1} sum_i R_i B_i p_i . +``` + +Define + +```text +T_i = A^{-1} R_i B_i . +``` + +Then + +```text +V = sum_i T_i p_i . +``` + +This is the `calcInverseWeight`, `calcPCACoefs`, and `calcPCA` structure in the +code.

It contributes to diagonal and mixed +Hessian elements. The second term is the residual-curvature term.

Parent momentum covariance + +The parent momentum is the sum of independent daughter momenta: + +```text +P = sum_i p_i, C_P = sum_i C_{p_i} . +``` + +For one O2 daughter track, + +```text +px = pt (csp cos(alpha) - snp sin(alpha)) +py = pt (snp cos(alpha) + csp sin(alpha)) +pz = pt tgl +``` + +with `pt = |q|/|q/pt|`. The charge is treated as exact and discrete. The +derivatives with respect to native momentum parameters `(snp, tgl, q/pt)` are + +```text +dpx/dsnp = -pt (snp cos(alpha)/csp + sin(alpha)) +dpy/dsnp = pt (cos(alpha) - snp sin(alpha)/csp) +dpz/dtgl = pt + +dpx/d(q/pt) = -px / (q/pt) +dpy/d(q/pt) = -py / (q/pt) +dpz/d(q/pt) = -pz / (q/pt) +``` + +and the omitted mixed derivatives in this Jacobian are zero: + +```text +dpx/dtgl = 0, dpy/dtgl = 0, +dpz/dsnp = 0 . +``` + +Let `A` be this 3 by 3 Jacobian and let `C_a` be the daughter covariance +submatrix in the native momentum-parameter order `(snp,tgl,q/pt)`. Then + +```text +C_p = A C_a A^T . +``` + +The six independent elements of `C_p` are accumulated into the O2 lab covariance +slots + +```text +cov[9], cov[13], cov[14], cov[18], cov[19], cov[20] +``` + +which correspond to + +```text +Cov(px,px), Cov(py,px), Cov(py,py), +Cov(pz,px), Cov(pz,py), Cov(pz,pz). +``` + +## 9. Parent track covariance + +The final lab covariance passed to the O2 parent constructor contains the fitted +vertex covariance and the summed parent momentum covariance: + +```text +C_lab = +[ C_V 0 ] +[ 0 C_P ] . +``` + +Position-momentum cross-covariances are not included in this approximation. +The existing O2 constructor + +```cpp +TrackParCov(xyz, pxpypz, cov, charge, sectorAlpha) +``` + +then transforms this lab covariance to the selected parent track frame, +including the parent `alpha` convention. + +## 10. Regularization of singular or weakly constrained covariance matrices + +### Single-track `TrackCovI` + +The matrix + +```text +I = H^T W H +``` + +has rank at most two for one track, because one track measures only the two +coordinates transverse to its own trajectory. The null direction is the local +track tangent + +```text +t = (1, y_prime, z_prime)^T . +``` + +Indeed + +```text +H t = 0, I t = 0 . +``` + +Therefore a single-track `TrackCovI` is positive semidefinite, not positive +definite. Inverting this 3D matrix by itself is not meaningful; the apparent +negative diagonal elements seen in such an inverse are numerical symptoms of +trying to invert a rank-deficient information matrix. The physically meaningful +inverse at single-track level is only the original 2 by 2 `(Y,Z)` covariance. + +For the multi-track vertex fit, different track directions usually make + +```text +A = sum_i R_i I_i R_i^T +``` + +full rank. However, nearly parallel or otherwise weak geometries can still make +the longitudinal eigenvalue very small. To avoid an exactly singular +single-track contribution while preserving the measured `(Y,Z)` block, the code +may add a weak positive longitudinal prior only to `I_XX`: + +```text +I_XX -> I_XX + 1/sigma_X,prior^2 . +``` + +In code this is implemented as + +```cpp +static constexpr float XRegErrFactor = 10.f; +... +if (xRegErrFactor > 0.f) { + sxx += 1.f / (cyy * xRegErrFactor); +} +``` + +This is different from multiplying `I_XX` by a number below one. A reduction of +`I_XX` can make the matrix indefinite, while adding a positive diagonal term +keeps the information matrix positive definite in the tangent direction and does +not alter `I_YY`, `I_YZ`, or `I_ZZ`. + +The regularization should remain weak. It is a numerical stabilizer for badly +conditioned geometries, not an additional detector measurement of the local +track `X` coordinate. For this reason it is applied **only** where an invertible +single-track contribution is actually required, i.e. for the `I_i` entering the +chi2 minimization (`mTrcEInv`, hence `calcInverseWeight()`, `calcPCACoefs()`, +`calcChi2()` and the Newton Hessian). `calcPCACovMatrix()` rebuilds the `I_i` +with `TrackCovI::XRegNone`: there the prior is not needed (the sum over prongs is +inverted, not the individual terms, and a genuinely ill-conditioned sum is +detected and replaced by a loose dummy covariance), and including it would make +the reported longitudinal vertex error follow the dummy `XRegErrFactor * C_YY` +instead of the track slopes. + +### `calcPCACovMatrix()` + +The vertex covariance is + +```text +C_V = A^-1, A = sum_i R_i I_i R_i^T . +``` + +If `A` is singular or ill-conditioned, returning a small fallback covariance +would incorrectly shrink the uncertainty along the weakly constrained direction. +The conservative behavior is: + +1. Check that `A` is compatible with a positive-definite information matrix. +2. Reject cases where the determinant is too small compared with the diagonal + scale. +3. Invert only when these checks pass. +4. If inversion fails, or if the inverted covariance has non-positive diagonal + elements, return a deliberately loose fallback covariance. + +The code uses the leading-minor checks + +```text +A_XX > 0, +det(A_XY block) > 0, +det(A) > epsilon max(diag(A))^3 +``` + +with + +```text +epsilon = 1e-12 . +``` + +On failure, it returns a diagonal covariance with + +```text +sigma^2 = 1e6 cm^2 . +``` + +This corresponds to a 10 m uncertainty in each coordinate. It is intentionally +loose: the fallback marks the parent vertex as poorly constrained rather than +creating an artificially precise parent covariance. + +## 11. Code changes summarized + +1. `TrackCovI` now stores a full symmetric local 3D information matrix. +2. The dummy `XerrFactor` approximation was removed. +3. PCA weights and chi2 derivatives now use `sxx,sxy,sxz,syy,syz,szz`. +4. PCA covariance is the inverse of the summed global information matrix. +5. The Hessian residual-curvature term is restricted to diagonal Hessian + elements. +6. `correctTracks()` now propagates the actual candidate track state with O2's + analytic constant-`Bz` transport, keeping `mCandTr` and `mTrPos` + synchronized. +7. `createParentTrackParCov()` now propagates daughter momentum covariance from + native O2 `(snp,tgl,q/pt)` parameters to lab `(px,py,pz)` before constructing + the parent `TrackParCov`. diff --git a/Common/DCAFitter/GPU/cuda/CMakeLists.txt b/Common/DCAFitter/GPU/cuda/CMakeLists.txt index ddc1d09445d7f..dfe9b6e515e9f 100644 --- a/Common/DCAFitter/GPU/cuda/CMakeLists.txt +++ b/Common/DCAFitter/GPU/cuda/CMakeLists.txt @@ -20,16 +20,19 @@ o2_add_library(DCAFitterCUDA O2::DetectorsBase PRIVATE_LINK_LIBRARIES O2::GPUTrackingCUDAExternalProvider) set_property(TARGET ${targetName} PROPERTY CUDA_SEPARABLE_COMPILATION ON) +# Device LTO, so that the device link can inline across the +# O2::GPUTrackingCUDAExternalProvider objects, which are compiled to LTO IR. +set_property(TARGET ${targetName} PROPERTY INTERPROCEDURAL_OPTIMIZATION ON) # add_compile_options(-lineinfo) -o2_add_test(DCAFitterNCUDA - SOURCES test/testDCAFitterNGPU.cxx - PUBLIC_LINK_LIBRARIES O2::ReconstructionDataFormats - O2::DCAFitterCUDA - O2::DCAFitter - ROOT::Core - ROOT::Physics - COMPONENT_NAME gpu - LABELS vertexing - ENVIRONMENT O2_ROOT=${CMAKE_BINARY_DIR}/stage - VMCWORKDIR=${CMAKE_BINARY_DIR}/stage/${CMAKE_INSTALL_DATADIR}) \ No newline at end of file +#o2_add_test(DCAFitterNCUDA +# SOURCES test/testDCAFitterNGPU.cxx +# PUBLIC_LINK_LIBRARIES O2::ReconstructionDataFormats +# O2::DCAFitterCUDA +# O2::DCAFitter +# ROOT::Core +# ROOT::Physics +# COMPONENT_NAME gpu +# LABELS vertexing +# ENVIRONMENT O2_ROOT=${CMAKE_BINARY_DIR}/stage +# VMCWORKDIR=${CMAKE_BINARY_DIR}/stage/${CMAKE_INSTALL_DATADIR}) diff --git a/Common/DCAFitter/GPU/cuda/DCAFitterN.cu b/Common/DCAFitter/GPU/cuda/DCAFitterN.cu index ed7e8acba5397..10ac99e1cc01f 100644 --- a/Common/DCAFitter/GPU/cuda/DCAFitterN.cu +++ b/Common/DCAFitter/GPU/cuda/DCAFitterN.cu @@ -16,6 +16,7 @@ #endif #include +#include #include "GPUCommonDef.h" #include "DCAFitter/DCAFitterN.h" diff --git a/Common/DCAFitter/GPU/hip/CMakeLists.txt b/Common/DCAFitter/GPU/hip/CMakeLists.txt index f62759bb6ea2c..5e7821a0b8946 100644 --- a/Common/DCAFitter/GPU/hip/CMakeLists.txt +++ b/Common/DCAFitter/GPU/hip/CMakeLists.txt @@ -21,15 +21,15 @@ o2_add_hipified_library(DCAFitterHIP PRIVATE_LINK_LIBRARIES O2::GPUTrackingHIPExternalProvider TARGETVARNAME targetNAme) -o2_add_test(DCAFitterNHIP - SOURCES ../cuda/test/testDCAFitterNGPU.cxx - PUBLIC_LINK_LIBRARIES O2::ReconstructionDataFormats - O2::DCAFitterHIP - O2::DCAFitter - ROOT::Core - ROOT::Physics - HIPIFIED test - COMPONENT_NAME gpu - LABELS vertexing - ENVIRONMENT O2_ROOT=${CMAKE_BINARY_DIR}/stage - VMCWORKDIR=${CMAKE_BINARY_DIR}/stage/${CMAKE_INSTALL_DATADIR}) \ No newline at end of file +#o2_add_test(DCAFitterNHIP +# SOURCES ../cuda/test/testDCAFitterNGPU.cxx +# PUBLIC_LINK_LIBRARIES O2::ReconstructionDataFormats +# O2::DCAFitterHIP +# O2::DCAFitter +# ROOT::Core +# ROOT::Physics +# HIPIFIED test +# COMPONENT_NAME gpu +# LABELS vertexing +# ENVIRONMENT O2_ROOT=${CMAKE_BINARY_DIR}/stage +# VMCWORKDIR=${CMAKE_BINARY_DIR}/stage/${CMAKE_INSTALL_DATADIR}) diff --git a/Common/DCAFitter/include/DCAFitter/DCAFitterN.h b/Common/DCAFitter/include/DCAFitter/DCAFitterN.h index df732bd4bde63..95248714a72ae 100644 --- a/Common/DCAFitter/include/DCAFitter/DCAFitterN.h +++ b/Common/DCAFitter/include/DCAFitter/DCAFitterN.h @@ -12,12 +12,13 @@ /// \file DCAFitterN.h /// \brief Defintions for N-prongs secondary vertex fit /// \author ruben.shahoyan@cern.ch -/// For the formulae derivation see /afs/cern.ch/user/s/shahoian/public/O2/DCAFitter/DCAFitterN.pdf +/// For the original derivation see /afs/cern.ch/user/s/shahoian/public/O2/DCAFitter/DCAFitterN.pdf +/// The AI-assisted readme is in DCAFitterN_derivation.md #ifndef _ALICEO2_DCA_FITTERN_ #define _ALICEO2_DCA_FITTERN_ -#include "DCAFitter/HelixHelper.h" +#include "ReconstructionDataFormats/HelixHelper.h" #include "DetectorsBase/Propagator.h" #include "MathUtils/Cartesian.h" #include "ReconstructionDataFormats/Track.h" @@ -28,17 +29,37 @@ namespace vertexing { ///__________________________________________________________________________________ -///< Inverse cov matrix (augmented by a dummy X error) of the point defined by the track +///< Inverse covariance matrix of the point defined by the track struct TrackCovI { - float sxx, syy, syz, szz; + // Independent elements of the symmetric 3D information matrix + // H^T Cyz^{-1} H.

Its purpose is to make common, physics-motivated track calculations available consistently to reconstruction, O2Physics analyses and calibration. More utilities can be added without changing the role of the package. + +**TrackGeometry** is the first component. It evaluates reconstructed tracks at requested detector radii and, for the TPC, estimates geometrically crossed, dead, edge-excluded and available pad rows and corresponding track lengths. This README documents **TrackGeometry**, not the scope of all future TrackTools components. + +## TrackGeometry: physics motivation + +**Shorter usable tracks generally mean worse tracking and PID performance:** less dE/dx information and poorer PID resolution, reduced reconstruction efficiency, potentially greater fit/PID biases and fake associations, and larger differences between data, simulation and reconstruction passes. We need to **quantify these effects track by track**, not merely describe them. TrackGeometry supplies common geometry-derived observables that analysts can use to study and select the *usable* portion of a track while separating geometric acceptance from reconstruction and calibration effects. + +A concrete Run 3 example is the **TPC sector-edge pad treatment**. In some early reconstruction passes, two pads at a sector boundary were treated as edge pads rather than one as in the earlier treatment. Edge-pad positions and amplitudes are intrinsically less reliable. Inflated cluster-position uncertainties reduce their contribution to the track fit, and excluding these pads from dE/dx shortens the segment available for PID. Charging-up and steep space-charge distortion gradients can amplify such effects. Later reconstruction changes appear to have alleviated part of the problem, but the exact treatment **must be checked for each production pass**; the library does not presume a correction date. + +The practical analysis question is therefore: *how many TPC pad rows, or how much track length, remain available if we exclude inactive regions and an adjustable guard near the **physical active-pad edge**?* A two-pad versus one-pad scenario can be studied by choosing guard widths appropriate to the detector geometry and reconstruction settings; **pad count is not itself a universal width in centimetres**. TrackGeometry provides the quantities for both selections, so one can correlate their effects with efficiency, fake rate, dE/dx resolution, PID biases and data/MC or pass-to-pass differences. + +A related, complementary measurement is the TPC cluster bitmask in TrackQA: eight bits summarize the 152 pad rows in eight groups of 19; in the current definition a bit is set when **more than five associated clusters** occur in that group. It can support studies of segment PID and potentially overlapping/split tracks, but it does **not** supply exact per-row reconstructed-cluster occupancy. TrackGeometry predicts geometric row availability; the bitmask describes coarse reconstructed-cluster information. Their comparison is useful precisely because the two are different observables. + +The same shared C++ component can return a track state and sector coordinate at an arbitrary **reachable** cylindrical radius, relevant to TPC, TRD and TOF studies. TPC-specific Mapper-based row/length acceptance is the first detector specialization; TRD/TOF detector-specific gap or strip acceptance is not implied by the generic query. + +The goal is to compute these observables **quickly and with controlled accuracy**, from the standard O2 track representation rather than reproducing tracking formulae in every analysis. In particular: + +- **L — stack-local linear approximation:** the candidate **fast** evaluator for repeated TPC row/length selections. +- **H — analytic helix:** constant-field reference against which the L approximation can be quantified. +- **K — O2 Propagator:** an independent transport reference for the TPC row calculation, requiring properly initialized O2 field conditions. Generic **K0** supplies constant-field O2 transport to a chosen radius. + +The practical objective is to establish the phase space where **L is both accurate enough and faster end-to-end**; H-derived endpoint construction must be included in its timing. The implementation supplies the comparison methods; this README does not claim an unmeasured speedup or universal accuracy threshold. + +A query at a TRD/TOF radius does **not** automatically calculate TRD chamber acceptance, TOF strip acceptance or arrival time; detector sector counts and phase conventions must be configured explicitly. + +## Input and functionality + +The preferred input is an existing full `o2::track::TrackPar`: local fitted parameters `(y, z, snp, tgl, q/pT)` at its reference plane `(x, alpha)`. It represents both primary and displaced/secondary tracks; do not replace a secondary's complete state with a primary-vertex approximation. The header also provides a reduced-primary adapter for older applications. All constant-field calls take an **explicit signed `Bz` in kG**, supplied from the data-taking conditions (GRP/CCDB) by the caller. + +Include the single component header in a configured O2 environment: + +```cpp +#include "TrackTools/TrackGeometry.h" +``` + +| Capability | Current C++ interface | +|---|---| +| Full track at a reachable cylindrical radius, H | `o2::recohelpers::getParametersAtRadiusH(track, radiusCm, signedBzKG)` | +| Same, constant-field O2 reference K0 | `o2::recohelpers::getParametersAtRadiusK0(track, radiusCm, signedBzKG)` | +| Position/momentum azimuth, inclination, fractional sector coordinate | `statePhiPos(state)`, `statePhiMom(state)`, `stateTgl(state)`, `stateDSector(state, nSectors, sectorPhaseRad)` | +| TPC available rows/length: linear L | `o2::tpc::recohelpers::sectorEdgeStackLinear(track, signedBzKG, cfg)` | +| Same: helix reference H | `o2::tpc::recohelpers::sectorEdgeHelixRows(track, signedBzKG, cfg)` | +| Same: initialized O2 Propagator K | `o2::tpc::recohelpers::sectorEdgeO2PropagatorRows(track, signedBzKG, cfg)` | +| Multiple full local states | `localTrackParametersAtRadiusHBatch`, `localTrackParametersAtRadiusK0Batch`, and `localSectorEdge{HelixRows,StackLinear,O2PropagatorRows}Batch` | + +The current candidate exposes the full-`TrackPar` H/L/K TPC row functions. It also retains primary-compatible overloads; the latter are **input adapters**, not separate geometry models. L is a TPC stack approximation, **not** a generic TRD/TOF straight-line propagator. + +For a TPC evaluation, `TPCSectorEdgeResult` provides four matching sets of quantities: + +| Classification | Predicted pad rows | Approximate trajectory length | Per-row mask | +|---|---|---|---| +| Crossed | `nRowsCrossed` | `lengthCrossedCm` | `crossedMask` | +| Dead: outside Mapper's physical active-pad boundary | `nRowsDead` | `lengthDeadCm` | `deadMask` | +| Excluded: *inside* that boundary, within the configured edge guard | `nRowsExcluded` | `lengthExcludedCm` | `excludedMask` | +| Available: inside the boundary and beyond the guard | `nRowsAvailable` | `lengthAvailableCm` | `availableMask` | + +The partition is `Crossed = Dead + Excluded + Available` for row membership and counts; lengths satisfy the corresponding sum up to floating-point roundoff. The masks encode 152 global pad-row indices, subdivided into **IROC (0–62), OROC1 (63–96), OROC2 (97–126), OROC3 (127–151)**, so per-stack counts can be calculated from the appropriate bits. Length estimates are geometric row-thickness contributions, not material-integrated paths. + +`TPCSectorEdgeConfig` specifies `guardLowerCm` and `guardUpperCm` (inward distances from the **active-pad edge**, not the nominal sector boundary), `zMaxCm` and `maxSnp` (the *radial-frame* inclination limit, distinct from the local `TrackPar::getSnp()`). The input track's reference radius and the first outward trajectory branch govern which rows are reachable. `stateDSector` returns a **fractional periodic sector coordinate**, not the physical distance to an active pad; supply the actual detector sector count and phase for non-TPC use. + +**Check results before using them:** `TrackParametersAtRadius::valid()` for radius queries and `result.status == o2::tpc::recohelpers::SectorEdgeStatus::OK` for row/length queries. The geometry-predicted row opportunities must not be confused with measured associated clusters or the subset of clusters used for PID. + +## C++ example 1 — compare two edge exclusions and make independent selections + +This is a typical use inside an O2 or O2Physics track loop. `track` is the actual fitted `o2::track::TrackPar`; `signedBzKG`, both guard widths and the cut threshold come from the **run/analysis configuration**. The two output counters are kept separately. Using **two configurations** on the same track makes it possible to compare selections across reconstruction passes or systematic variations. + +```cpp +#include "TrackTools/TrackGeometry.h" + +// Call this in an O2/O2Physics track loop. The run configuration supplies +// signedBzKG, both guard widths and minAvailableRows. +void countEdgeSelections(const o2::track::TrackPar& track, + float signedBzKG, + float guard0Cm, float guard1Cm, + int minAvailableRows, + unsigned& nRejected0, unsigned& nRejected1) +{ + namespace tg = o2::tpc::recohelpers; + tg::TPCSectorEdgeConfig cfg0; + cfg0.guardLowerCm = cfg0.guardUpperCm = guard0Cm; + cfg0.zMaxCm = 250.f; // set from desired longitudinal acceptance + cfg0.maxSnp = 0.9f; // radial-frame trajectory stopping criterion + + auto cfg1 = cfg0; + cfg1.guardLowerCm = cfg1.guardUpperCm = guard1Cm; + + // Two independent predictions for the same complete TrackPar. + // Use L for selections after verifying its accuracy in your phase space. + const auto result0 = tg::sectorEdgeStackLinear(track, signedBzKG, cfg0); + const auto result1 = tg::sectorEdgeStackLinear(track, signedBzKG, cfg1); + if (result0.status != tg::SectorEdgeStatus::OK || + result1.status != tg::SectorEdgeStatus::OK) { + return; // Handle non-OK tracks separately in your analysis. + } + + const int nRowsCut0 = result0.nRowsAvailable; + const int nRowsCut1 = result1.nRowsAvailable; + const float lengthCut0Cm = result0.lengthAvailableCm; + const float lengthCut1Cm = result1.lengthAvailableCm; + + if (nRowsCut0 < minAvailableRows) { + ++nRejected0; // Edge treatment 0: independent selection. + } + if (nRowsCut1 < minAvailableRows) { + ++nRejected1; // Edge treatment 1: independent selection. + } + // The same two results allow length-based cuts on lengthCut{0,1}Cm. + (void)lengthCut0Cm; + (void)lengthCut1Cm; +} +``` + +Changing the guard changes **Excluded/Available**, not the physical Mapper **Dead** classification. For a systematic comparison, keep both decisions rather than overwriting the first. If L accuracy for your sample has not yet been established, call `sectorEdgeHelixRows` on the same full track and compare available rows, available length, row masks and selection decisions. + +## C++ example 2 — interactive ROOT, one question at a time + +This is a **real, user-executed ROOT/Cling session** using the full-5D candidate header, not pseudocode or a compiled macro. It shows the workflow that can then be moved almost unchanged into an O2Physics track loop: start with one track, inspect `dSector`, vary the active-pad-edge guard, read out the available rows and lengths, apply two cuts, and compare L with H. + +Start a **fresh ROOT session** in the O2 environment from the O2 repository root. Use the public `include/TrackTools/` layout; the same `#include "TrackTools/TrackGeometry.h"` works in compiled O2 applications. + +```bash +ROOT_INCLUDE_PATH="$PWD/Common/TrackTools/include${ROOT_INCLUDE_PATH:+:$ROOT_INCLUDE_PATH}" root -l +``` + +The header-only `O2::TrackTools` CMake target installs the public header under `TrackTools/`. The following expressions are entered **one line at a time** at the ROOT prompt; no multiline `std::cout` statement is required. + +### 1. Construct a complete local O2 track and query the 85 cm surface + +```cpp +#include "TrackTools/TrackGeometry.h" +#include +namespace geo = o2::recohelpers; +namespace tpc = o2::tpc::recohelpers; + +const float bzKG = 5.f; +auto track = geo::makeTrackParFromLocalParameters(80.f, 0.12f, -9.5f, 17.f, 0.06f, 0.25f, 0.30f); +auto at85 = geo::getParametersAtRadiusH(track, 85.f, bzKG); +at85.valid() +geo::stateDSector(at85, 18, 0.f) +at85.gz +geo::statePhiMom(at85) +``` + +Actual ROOT results: + +```text +(bool) true +(float) 0.0319329f // fractional sector coordinate at R=85 cm +(float) 18.1262f // global z at R=85 cm [cm] +(float) 0.178010f // global momentum azimuth [rad] +``` + +`bzKG=+5` is a **synthetic demo setting**, not a production field default. In production obtain the signed field and conditions from the actual run. The initial state is local `(x, alpha, y, z, snp, tgl, q/pT)` and may represent a displaced track; it is not silently reset to the primary vertex. For other detectors use the actual sector count and phase, not necessarily the TPC's `18, 0` convention. + +### 2. Define two edge-guard configurations + +```cpp +tpc::TPCSectorEdgeConfig cfg0; +cfg0.guardLowerCm = 0.5f; +cfg0.guardUpperCm = 0.5f; +cfg0.zMaxCm = 250.f; +cfg0.maxSnp = 0.9f; +auto cfg1 = cfg0; +cfg1.guardLowerCm = 1.5f; +cfg1.guardUpperCm = 1.5f; +``` + +Guard distances are **centimetres inward from the Mapper active-pad boundary**, not distances from the nominal 20° sector boundary. The numbers demonstrate a guard scan, not certified conversions of one versus two physical pad widths. + +### 3. Calculate available rows and useful length under each guard + +```cpp +auto l0 = tpc::sectorEdgeStackLinear(track, bzKG, cfg0); +auto l1 = tpc::sectorEdgeStackLinear(track, bzKG, cfg1); +int(l0.status) +int(l1.status) +l0.nRowsAvailable +l1.nRowsAvailable +l0.lengthAvailableCm +l1.lengthAvailableCm +``` + +Actual ROOT results: + +```text +(int) 0 +(int) 0 +(unsigned short) 143 +(unsigned short) 134 +(float) 153.057f +(float) 146.054f +``` + +For the same reconstructed track, increasing the guard decreases the predicted available rows from **143 to 134**, and the available length from **153.057 to 146.054 cm**. A real analysis should retain non-OK statuses separately rather than treating failed geometry evaluations as accepted rows. + +### 4. Make independent analysis selections + +```cpp +const int minRows = 140; +bool reject0 = int(l0.status) != 0 || l0.nRowsAvailable < minRows; +bool reject1 = int(l1.status) != 0 || l1.nRowsAvailable < minRows; +reject0 +reject1 +``` + +Actual ROOT results: + +```text +(bool) false // 0.5-cm guard: ACCEPT, 143 >= 140 +(bool) true // 1.5-cm guard: REJECT, 134 < 140 +``` + +This is the direct use case for an O2Physics task: compute `nRowsCut0` and `nRowsCut1` from two configurations of the **same fitted `TrackPar`**, then keep both acceptance decisions. `minRows=140` is an **illustrative** threshold to make the difference visible, not a recommended universal analysis cut. Available-length cuts work analogously using `lengthAvailableCm`. + +### 5. Quantify how much the fast L method differs from H + +```cpp +auto h1 = tpc::sectorEdgeHelixRows(track, bzKG, cfg1); +int(h1.status) +int(h1.nRowsAvailable) - int(l1.nRowsAvailable) +h1.lengthAvailableCm - l1.lengthAvailableCm +``` + +Actual ROOT results: + +```text +(int) 0 +(int) 6 +(float) 4.58417f +``` + +For this **near-edge, deliberately demanding example**, H and L differ by **6 available rows and 4.58417 cm**. Thus agreement of H and L must be checked in the analysis phase space before substituting the faster approximation for a cut. No blanket speedup or precision claim follows from a single-track demonstration. + +For a generic detector-surface query, the same full-state API also evaluated a state at an illustrative radius of 300 cm in the compiled demonstration: + +```cpp +auto at300 = geo::getParametersAtRadiusH(track, 300.f, bzKG); +at300.valid() +``` + +The 300-cm point is an example cylinder, **not** a claim that TRD/TOF-specific acceptance is implemented. A user can next vary `y`, signed `q/pT`, `tgl`, `guardLowerCm`, `guardUpperCm`, or the requested radius interactively and inspect the resulting quantities. Because these are ordinary C++ calls, they transfer to compiled O2 or O2Physics code without a second geometry implementation. + +## Tests included with TrackGeometry + +The portable O2/PyROOT tests call the same C++ header. They are intended to be runnable without AliasDataFrame or dfdraw. In the O2 checkout, after loading the matching O2/ROOT environment: + +```sh +cd O2/Common/TrackTools # replace with your actual checkout path +python -m pytest -q -ra test/python +``` + +The portable test sources supplied with TrackTools include: + +- `test/python/conftest.py`: load the same ROOT environment and `TrackGeometry.h` used by C++. +- `test/python/test_full_state_radius.py`: full 5D H/K0 radius evaluation, independent straight-line truth for displaced tracks, field/charge-sign and invalid-input checks. +- `test/python/test_sector_rows_primary_baseline.py`: TPC Mapper's 152-row accounting, mask partitions, guard monotonicity and the recorded row-centre expected failure. +- `test/python/test_full_state_tpc_rows.py` **in the extended full-5D test set**: full-state H/L, reduced-primary adapter equivalence, displaced tracks, first-outward start radius, scalar/batch parity and field-initialized K smoke checks. Run this file in O2 only once its exact committed version is present in that checkout. + +The historical focused full-state portable run was reported as **26 passed, 1 expected failure** in dEdxAI; this is not a statement that the entire O2 test suite or O2 CTest has passed. Test counts belong to the exact source revision and should be updated from the PR's attached log. The row-centre finding is an expected failure, not a passing geometry oracle. + +For developers in the canonical **dEdxAI** source tree, the focused tests (including the extended full-state tests) run from the repository root: + +```sh +O2RECO_GRP="$dEdxAI_CODE/o2sim_grp.root" \ +TRACKTOOLS_INCLUDE="$dEdxAI_CODE/o2reco/cpp" \ +python -m pytest -v -ra tests/o2reco/portable_o2/ +``` + +Run the project's canonical `run_tests.sh` and attach its actual output, O2 build status and source revision to the PR/CRR when available. An expected failure for the Mapper row-centre condition is **not** a passing physical validation. The detailed K and row-centre investigations belong in technical review evidence; use method K only with initialized O2 field conditions and appropriate validation. + +## Python and AliasDataFrame example + +The **optional dEdxAI Python demonstration** calls the C++ TrackGeometry implementation through PyROOT and plots useful TPC geometry observables with AliasDataFrame/dfdraw.

Each column is one TPC stack and the facets separate true origin-produced primaries (`isPrimary=1`) and displaced secondaries (`isPrimary=0`). The example uses H, full 5D input, a synthetic **+5 kG** field, and **1.5 cm guards** on both active-pad edges. It is a **constructed 50/50 mixture** of 500 primaries transported from `(0,0,0)` to reference radii 78–82 cm, and 500 displaced secondaries sampled around reference `x` positions 79, 80, 81, 105, 145 and 195 cm with ±1.5 cm smearing, broad local `y,z` and random signed curvature. Conditioning on a successful *outward* R=85 cm state removes most secondaries starting at larger radii; it is not a realistic detector-production spectrum. The figure illustrates geometry dependence, **not H–L precision, L timing or measured Ncl**. + +To investigate those comparisons in Python, keep the same `adfSynthetic` sample and inspect H versus L available-row and length differences in the data; an H-only scatter plot is not a substitute for the L validation benchmark. + +--- + +**Component status.** `TrackGeometry.h` is the implemented component covered above. Some field/curvature and physical pad-row-centre validation remains under technical review, while O2 build/CI validation remains under technical review.

Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser +General Public License, and the "GNU GPL" refers to version 3 of the GNU +General Public License. + + "The Library" refers to a covered work governed by this License, +other than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided +by the Library, but which is not otherwise based on the Library. +Defining a subclass of a class defined by the Library is deemed a mode +of using an interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an +Application with the Library. The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + + The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the +Library as you received it specifies that a certain numbered version +of the GNU Lesser General Public License "or any later version" +applies to it, you have the option of following the terms and +conditions either of that published version or of any later version +published by the Free Software Foundation. If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + + If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library. + + + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU General Public License is a free, copyleft license for +software and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. But first, please read +. diff --git a/Detectors/3rdparty/FairRootBase/README.md b/Detectors/3rdparty/FairRootBase/README.md new file mode 100644 index 0000000000000..4494faf842c00 --- /dev/null +++ b/Detectors/3rdparty/FairRootBase/README.md @@ -0,0 +1,24 @@ +# FairRootBase + +This directory holds the part of [FairRoot](https://github.com/FairRootGroup/FairRoot) that the O2 +simulation uses: the VMC application, module and detector base classes, the run, sink and root +manager, the generic stack, the event headers and a few helpers around them.

A cone may have zero radius at one end (apex cone). + +A quadric or torus patch is trimmed either by a scalar parametric rectangle (phi sweep times +height, theta or tube range) or by a general wire in its (u, v) domain. With a wire, the wire is +authoritative for containment and the scalar parameters only fix the frame and a conservative +window. A wire trim may not wrap more than one full turn in any periodic angle. + +The `innerWall` flag reverses the outward normal of a quadric or torus: it then points towards the +axis, the centre or the tube spine. It marks a hole wall. + +### 1.2 Trim curves and wires + +A trim curve (`Curve2D`) is one of three kinds: + +- a line segment; +- a circular arc: centre, radius, start angle and signed sweep (a full circle is a sweep of ±2π); +- a clamped B-spline, optionally rational: degree, poles, weights, flat knot vector. + +B-splines are evaluated by de Boor. Their enclosed area is integrated by Gauss-Legendre per knot +span, which is exact for non-rational curves. Point-in-wire winding and point-to-curve distance use +one cached flattened polyline per curve. The flattener subdivides until each chord is within +`kBSplineFlatness` of the curve, judged at t = 1/4, 1/2 and 3/4 of the interval, and it never +declares an interval flat while it still contains an interior knot. + +A wire (`CurveWire` for curves, `SurfaceWire` for polygons) is one closed loop. A face has one +outer wire and any number of inner wires (holes). Wires are normalised to outer counter-clockwise +and inner clockwise; a re-orientation is logged. A wire is rejected when it is non-finite, open, +of zero area or self-touching. Consecutive curve endpoints must meet within the wire-join band, +measured as a 3D length through the surface's first fundamental form. + +### 1.3 Public construction API + +```cpp +bool AddPlanarSurface(origin, axisU, axisV, outerWire, innerWires = {}); +bool AddCurvedPlanarSurface(origin, axisU, axisV, outerWire, innerWires = {}); +bool AddCylindricalSurface(centerPoint, axis, referenceAxisU, radius, heightMin, heightMax, + phiStart = 0, phiSweep = 2pi, innerWall = false); +bool AddConicalSurface(centerPoint, axis, referenceAxisU, radiusAtMin, radiusAtMax, + heightMin, heightMax, phiStart = 0, phiSweep = 2pi, innerWall = false); +bool AddSphericalSurface(center, polarAxis, referenceAxisU, radius, thetaMin = 0, thetaMax = pi, + phiStart = 0, phiSweep = 2pi, innerWall = false); +bool AddToroidalSurface(centerPoint, axis, referenceAxisU, majorRadius, minorRadius, + phiStart = 0, phiSweep = 2pi, tubeStart = 0, tubeSweep = 2pi, + innerWall = false); +``` + +Each quadric and the torus has a second overload that appends `outerTrim` and `innerTrims` as +vectors of `PlanarBoundaryCurve`, the public mirror of `Curve2D` (`makeLine`, `makeArc`, +`makeBSpline`). `AddCurvedPlanarSurface` requires orthonormal axes; its outward normal is +axisU × axisV. + +`SetSurfaceBoundaryEdges(surfaceIndex, edgeIds, edgeFlags)` attaches the source-edge identity of a +face (section 4.2). `SetModelTolerance(cm)` records the source model's declared tolerance; zero +means "not stated". + +### 1.4 `CloseShape(check = true)` + +`CloseShape` computes the bounding box, the display mesh, the safety anchors, the BVH and the +closure diagnostics, in that order. With `check` set, closure defects are reported as `Error` +messages that state the consequence for navigation. A solid with no surfaces stays undefined and +reports `NavigationReliability::Undetermined`. + +### 1.5 The BVH + +The BVH is a `bvh::v2` float BVH over **cover boxes**, with one cover box per leaf. Each surface +supplies its cover boxes through `appendCoverBoxes`. Their union must contain both the trimmed +patch (every ray hit and on-surface point) and every point at which `distanceSqToPatch` can be +realised, so that one BVH serves the ray and the nearest-patch traversals. + +- Planes use one box. +- Cylinders and cones split their sweep into chunks of at most `kCoverChunkAngle` (π/4), each + bounded exactly. +- Spheres and tori cover the full surface of revolution, because their distance kernels project + onto the whole surface and ignore the trim. + +Every box is widened by `kBVHBoxTolerance` and rounded outward to float. Because a surface can own +several leaves, each traversal hands each surface on only once, using an epoch-stamped +`thread_local` marker. + +## 2. Queries + +All queries fall back to their loop version before `CloseShape` has built the BVH. + +### 2.1 `Contains` + +1. A point outside the bounding box (plus `kTolerance`) is outside. +2. A point within `kTolerance` of any patch is inside. Candidate patches come from a BVH + point-in-box traversal. +3. Otherwise the answer is the parity of the crossings along a fixed skew direction + (1, √2, √3), normalised. Hits within `kIntersectionTolerance` of each other form a cluster. + A cluster whose hits all enter, or all exit, is one crossing. A cluster that mixes entering and + exiting hits is a graze and counts as none. + +On a `Reliable` solid (section 4) one parity shot is the answer, unless a counted hit carried +`onTrimBoundary`. That flag means the hit lay inside its patch's on-boundary band, where the trim +test resolves the tie as "inside the trim". The solid then re-shoots. + +On any other solid, and on a re-shoot, `Contains` takes a majority vote over five golden-spiral +directions and stops once three agree. Shots that rest on a trim tie-break are counted apart and +decide only when the other shots are tied. + +### 2.2 `DistFromOutside` and `DistFromInside` + +Both call one template, `nearestCrossing`. Entering and exiting are decided by the +sign of normal · direction. The traversal is `bvh->intersect` with a leaf +lambda. As candidates are found, the ray's `tmax` shrinks to the best candidate plus a cluster +margin, rounded up by `kBVHBoxTolerance` and one float ulp. This prunes nodes beyond the best hit +without losing the hits that decide whether that candidate is a crossing or a graze. + +If the nearest candidate turns out to be a graze, the query is repeated without pruning. Hits are +accepted from `-kRayTolerance` so that a crossing at the origin is not lost. `stepmax` bounds the +traversal and the result. `DistFromOutside` first rejects a point whose gap to the bounding box +exceeds `stepmax + kBVHBoxTolerance` on any axis. + +Both follow ROOT's `iact` contract. For `iact` below 3, and with a `safe` pointer, they first +compute `Safety` into `safe`. They then return `TGeoShape::Big()` without tracing the ray for +`iact` 0, and for `iact` 1 when `stepmax` is below the safety. `iact` 3 computes no safety. + +### 2.3 `Safety` and `ComputeNormal` + +`Safety` is the exact distance to the nearest patch, found by an ordered BVH descent with a +running best. Nodes are pruned on their box distance, scaled down by (1 − 1e-12) so the bound +stays a lower bound. The running best is seeded from 24 display vertices (the safety anchors), +which lie on patches and so give an upper bound. The result is rounded down by one ulp. The `in` +argument is not used. + +Per patch, `distanceSqToPatch` is exact for planes and for untrimmed quadrics. For wire-trimmed +patches, and for sphere or torus points whose projection falls outside the trim, it is a +conservative lower bound. `Safety` is therefore always a valid underestimate. + +`ComputeNormal` uses the same traversal to find the nearest patch. It returns that +patch's outward normal, flipped to point along `dir`. + +### 2.4 `Capacity` + +`Capacity` is the absolute value of the sum of each patch's divergence-theorem contribution, +(1/3)∫X·n dA over the trimmed patch. `GetSurfaceCapacityContributions` returns the terms. + +- Polygons, curved planes without B-spline trims, and untrimmed quadrics and tori have closed forms. +- Wire-trimmed quadrics and tori integrate by Green's theorem around the trim wire, with + 20-point Gauss-Legendre per piece and pieces no wider than π/4 in u. `capacityIsExact()` is false + for them, but the result is accurate to rounding on a closed solid. +- A curved plane with a B-spline trim reports `capacityIsExact()` false. + +On an open solid, `Capacity` measures the closure defect as well as the volume. + +### 2.5 Visualisation and sampling + +Each surface emits its own display triangulation, with `kArcSamples` (24) chords per full turn. +`GetBuffer3D`, `SetPoints` and `SetSegsAndPols` use it. Navigation never depends on it; only the +safety seed reads display vertices, and only as an upper bound. + +`GetPointsOnSegments`, used by `TGeoManager::CheckOverlaps`, projects each sample back onto its +exact patch to within `kSurfacePointTolerance` (1e-11 cm). It returns `kFALSE` when fewer points +than display vertices are requested, so that ROOT falls back to `SetPoints`. + +### 2.6 Loop twins and diagnostic hooks + +`Contains_Loop`, `DistFromOutside_Loop`, `DistFromInside_Loop`, `Safety_Loop` and +`ComputeNormal_Loop` visit every surface without the BVH. They share the per-hit logic with the +accelerated queries, so the two must agree bit for bit. They serve both as the oracle and as the +performance baseline. + +Diagnostic hooks: + +- `ContainsAlongDirection` is parity along one explicit direction, without the re-shoot policy. +- `DescribeContainsCrossings` returns the crossing list of the BVH and of the loop. +- `CountBVHRayCandidates`, `HasBVH` and `GetBVHRootBounds` inspect the BVH. +- `SetRayTMaxPruning`, `ResetRayCandidateCounter` / `GetRayCandidateCount` and + `ResetSafetyCandidateCounter` / `GetSafetyCandidateCount` price the pruning. +- `SetSafetyBoundUnsoundForTest` is a negative control for the tests only. + +The measurement switches are process-wide and must not be flipped while queries run. Scratch +buffers and traversal stacks are `thread_local`, so queries allocate nothing after warm-up. The +B-spline polylines are built with their wire, so a query only reads the shared shape and is safe +to call from several threads. + +## 3. Persistence + +The solid persists the sequence of `Add*Surface` calls as `BVHSurfaceRecord`s (with their curves as +`BVHSurfaceCurveRecord`s), the source-edge identities, and the model tolerance. The custom +`Streamer` reads the records, replays them through `Add*Surface` and calls `CloseShape`, so the +closure diagnostics of a read-back solid are recomputed. A solid with no records reads back +undefined and not navigable. The class version is 3. + +## 4. Closure and navigation reliability + +Parity containment is defined only on a closed, consistently oriented 2-manifold. `CloseShape` +decides which case applies and reports it as `NavigationReliability`: + +| state | meaning | consequence | +| --- | --- | --- | +| `Undetermined` | `CloseShape` has not run, or the solid is empty | no answer is trusted | +| `Reliable` | closed and consistently oriented | single-shot parity | +| `ReversedFaces` | a shared boundary is traversed the same way by both faces | distance queries may return the wrong side | +| `OpenSurfaceSet` | a trim loop has no neighbouring face | wrong answers in the shadow of each gap | +| `NonManifold` | a trim loop runs along two or more other faces | parity is not well defined | + +The states are ordered by severity; the worst one present is reported. `IsNavigable()` is true +only for `Reliable`. A solid that is not navigable still answers every query. + +### 4.1 Rim matching (the default) + +Each face emits one 3D polyline per trim loop (a rim). Each chord midpoint of a rim is matched +against the chords of every other face. A chord counts as matched when another face's chord lies +within the rim-match tolerance plus the sampling sagitta of both chords. The rim-match tolerance is +the model tolerance, or `kRimMatchTolerance` when none is stated. The non-manifold test uses the +tolerance alone, without the sagitta. + +Reversed duplicate edges inside one face (a seam) cancel before chaining. Rims are chained by +matching endpoints. + +`GetRimReports()` returns one record per rim, with its face, loop, chord count, length, unmatched +length and state. `GetMaxRimIsolation()` is the largest distance from any chord to the nearest +chord of another face. It measures how isolated the loneliest chord is, not the width of a seam, +and it does not change with the tolerance. `GetRimChordResolution()` is the sampling floor below +which rim distances mean nothing. + +The per-chord counters (`GetBoundaryEdgeCount` and its siblings) remain as diagnostics only. + +### 4.2 Edge identity (sidecar version 3) + +When every face states its source edges, closure is decided by counting instead of by proximity. +Every edge must be used exactly twice, in opposite senses. Degenerate edges (a cone apex or sphere +pole) are excluded from the count. + +`GetMaxSharedEdgeDeviation()` then reports, as a measurement only, the largest symmetric Hausdorff +distance between the two faces' realisations of one shared edge. Each realisation is sampled at 33 +points. Only anchored edges can be measured. If any face states no edges, the rim verdict of 4.1 +applies in full. + +## 5. Surface sidecar format (`surfaces__.bin`) + +The format is written by `write_surfaces_bin` in `O2_CADtoTGeo.py` and read by +`o2::cad::LoadSurfaceSolid`.

At each box, every halfspace still active in the +parent is classified with a rigorous range bound of sign · f over the box: + +- **Quadric:** with centre m, half-extents h and g = Am + b, + |Q(x) − Q(m)| ≤ 2Σ|gᵢ|hᵢ + Σ|Aᵢⱼ|hᵢhⱼ. +- **Torus:** the signed distance is 1-Lipschitz, so f ∈ [f(m) − ‖h‖, f(m) + ‖h‖]. + +Both bounds are padded by `kPadFactor` times the magnitude accumulated when evaluating f(m). + +For each box and halfspace: + +- if min(sign · f) > 0, the box is outside the cell and is dropped; +- if max(sign · f) ≤ 0, the halfspace holds everywhere in the box and leaves its active list; +- otherwise the halfspace stays active. + +A box whose active list is empty lies wholly inside its cell. + +Splitting stops, and the box is kept, when any of these holds: + +- the active list is empty; +- the depth budget (`fSplitDepth`, 4) is spent; +- the longest side is no larger than `fMinBoxFraction` (0.05) times the part diagonal; +- the box is still far from cubic once the cubify budget (`kMaxCubifySplits`, 10 per + root-to-leaf path) is spent. + +A split is charged to the cubify budget, not the depth budget, while the box is far from cubic +(longest > 2 · max(shortest, minSize)). Halving the longest extent of a box with ratio ≤ 2 keeps +the ratio ≤ 2. A box that starts near-cubic therefore never draws on the cubify budget, and its +tree is the same as under a depth-only rule. Flooring `shortest` at `minSize` stops a flat cell +from spending the cubify budget on an axis that is never split. + +All surviving boxes of all cells go into one `bvh::v2::Bvh`. An over-wide range bound loses +pruning, never correctness. + +**The cell box is a correctness obligation on the converter.** No box is ever built outside it, +so material outside the declared box is invisible to the accelerated queries but visible to the +twins. The converter supplies the bounding box of the CAD piece the cell came from, widened by +`_FLAT_BOX_MARGIN`. It refuses the part (`_flat_box_holds_cell`) if an outward probe finds the +cell extending past that box. `emit.crosscheck_contains` then compares `Contains` against +`Contains_Loop` on the shipped shape. + +`CloseShape` refuses, and builds nothing, when a cell box is unset, inverted or non-finite. Debug +builds also sample a 5×5 grid on each box face, offset outward by 1e-6 of the diagonal, and require +every sample to be outside the cell. + +### 4.3 What the boxes buy + +- Tight boxes on long, diagonal and curved cells. +- Short active lists: a query evaluates only the few halfspaces undecided in its box. +- A rigorous `Safety` without any point-to-quadric distance formula (section 5.4). + +### 4.4 The correctness invariant + +An active list describes the cell only inside its own box. Every ray query clips the ray to a +box's slab interval before it runs the interval clipping over that box's list. Gathering active +lists across boxes and clipping once is wrong. The `_Loop` twins exist mainly to catch a violation +of this rule. + +## 5. Queries + +All accelerated queries fall back to their twin when `IsClosed()` is false. + +### 5.1 `Contains` + +`Contains` finds the boxes containing the point. A box with an empty active list answers inside at +once. Otherwise the point is inside if every active halfspace of the box satisfies +sign · f(p) ≤ 0. Cells are disjoint, so the first box that says yes decides. + +### 5.2 Distances + +Within one box, along the ray clipped to the box, the query collects the roots of every active +halfspace. A quadric gives at most two roots of αt² + 2βt + γ, with α = dᵀAd, β = dᵀ(Ao + b) and +γ = Q(o). When α ≈ 0 the equation is solved as linear. A torus gives at most four roots. The roots +are sorted, and the midpoint of each sub-interval is classified. The result is the cell's occupancy +as a set of intervals. No convexity is assumed, which is required because complemented halfspaces +make cells non-convex. + +The traversal visits the boxes the ray meets, rejoins each cell's pieces across boxes, and then +applies the tolerance rule: an interval counts only if its exit clears `TGeoShape::Tolerance()`. +This makes the result independent of the order in which boxes are visited, and equal to the twin. +`DistFromOutside` also keeps a running bound on the nearest entry and skips every box the ray +enters beyond it. Each box it keeps is still clipped to [0, step], so the answer does not change. + +- `DistFromOutside` is the first entry at t > 0. +- `DistFromInside` is the far end of the interval of the union across cells that contains t = 0. + +Both follow ROOT's `iact`/`step` contract: for `iact` below 3 they compute `Safety` first, and +`iact` 0, or `iact` 1 with `step` below the safety, returns without tracing. Scratch buffers and +traversal stacks are `thread_local`. + +### 5.3 `Capacity` + +`Capacity` is the sum of the per-cell volumes, which the converter takes from OCCT `GProp` on each +source piece. The cells are disjoint, so no inclusion–exclusion is needed. The value is inherited +from OCCT rather than computed from the shipped solid. + +### 5.4 `Safety` + +- **Outside:** the distance to the nearest box is a lower bound, because every point of the solid + lies in some box. +- **Inside:** in a box with an empty active list, the distance to that box's faces is a bound. In + an undecided box the answer is 0. + +### 5.5 The rest of the `TGeoShape` contract + +`ComputeBBox` is the union of the retained boxes, which is tighter than the union of the cell +boxes. `ComputeNormal` is the gradient of the active halfspace closest to equality: 2·sign·(Ax + b) +for a quadric, or the signed-distance gradient for a torus. It is normalised and oriented along +`dir`. Drawing follows `O2Tessellated`. + +`GetPointsOnSegments` fires deterministic rays from the boxes that carry boundary and keeps a +crossing only where `Contains` changes within `kFlipProbe` either side, so a face shared by two +cells never yields a point. The overlap check (`O2OverlapCheck`) applies the same flip test to +every `O2FlatCSG` point it samples, because `Safety` is 0 inside an undecided box and so cannot +show that a point is on the boundary. + +## 6. The `_Loop` twins + +`Contains_Loop`, `DistFromOutside_Loop` and `DistFromInside_Loop` walk all cells and all +halfspaces, without the BVH and without active lists. They define the answer, and the tests require +bit identity with the accelerated queries. `Safety_Loop` walks all boxes without the BVH. It must +equal `Safety` and must also be a sound bound. + +## 7. Persistence + +The generated `geom.C` constructs the shape and fills it with `LoadFlatCSG(file, solid)` from +`flatcsg__.bin`, then calls `CloseShape()`. The BVH and the sub-cell boxes are never +stored; they are rebuilt on load. + +The class also has an automatic ROOT streamer. A `#pragma read` rule in `CADSupportLinkDef.h` calls +`CloseShape()` on every object read, and reports an error if the build is refused. A shape read +from a file is therefore closed; only a shape built by hand needs an explicit `CloseShape()`. + +### 7.1 Flat-CSG sidecar format (`flatcsg__.bin`) + +The format is read and written by `o2::cad::LoadFlatCSG` / `WriteFlatCSG`. The production writer is +`tools/cadsupport/flat.py`; the two writers must agree byte for byte.

The layout of `c` is given in 3.1; + unused slots are written but ignored. +- `first` and `count` give the cell's halfspace range. The loader rejects first < 0, count ≤ 0 and + first + count > nHalfspaces. It also rejects an unknown `kind`, a non-finite coefficient and a + torus with a zero axis. +- `volume` is the OCCT volume of the source piece. +- `lo` and `hi` are the cell box passed to `SetCellBBox`: an outer bound owed by the converter. + +Records are packed without padding: 100 bytes per halfspace and 64 bytes per cell. They are read +field by field, because the natural C++ struct pads to 104 bytes. The loader checks the remaining +file length against nHalfspaces·100 + nCells·64 before reading any record, so a truncated or +overlong file is refused. `WriteFlatCSG` refuses a shape that is not closed, because its unset cell +boxes would be written as zeros. + +## 8. The converter side + +The decomposition (`tools/cadsupport/decompose.py`) splits a part into cells at trusted concave +edges. Its budget covers the whole working set of cells, pending pieces and unresolved pieces: +`PART_MAX_CELLS` = 64, `MAX_SPLITS` = 256 and `TIMEOUT_S` = 60 s by default. The converter can raise +all three with `--max-cells`, `--max-splits` and `--decompose-timeout`. + +The flat emitter (`tools/cadsupport/flat.py`) maps each carrier from `_halfspace_carriers` directly +to a quadric or torus block. The flat path has its own budgets, `_PART_MAX_FLAT_CELLS` = 256 and +`_PART_MAX_FLAT_HALFSPACES` = 1024. The tree path keeps `_PART_MAX_LEAVES` = 64. + +Ordering rules: + +- The flat path runs last, after every whole-part matcher, the single-cell reading and the + union-of-cells tree have declined. No part that another tier accepts changes representation. +- A one-piece decomposition keeps the whole-part guards: an all-planar body belongs to the prism + templates and a one-carrier body to the tier-1 templates. The flat path does not overrule them. +- A single cell is admissible in the class and in `primitives.flat_cells`. + +## 9. Open measurements + +- The crossover between flat and composite emission, in cells and in halfspaces. +- The split parameters (depth, minimum box size, cubify budget) against leaf list length, box + count, memory and query cost. +- `Safety` quality against the true distance, since a sound but weak bound costs transport steps. + +## 10. Acceptance + +A flat part ships only if it passes the same tests as any CSG part: the OCCT symmetric difference +within tolerance, the oracle gate, and `checkKnownSource.py` against the source `TGeoShape` when +one exists. The false-accept guard `accept.contains_disagreements` also runs, because +`BRepAlgoAPI_Cut` can report success with no solid in either direction. + +## 11. Risks and limits + +1. **The sign convention** is the likeliest silent error. It is mitigated by the check against + `_cell_leaf`. +2. **The clip-inside-the-box rule** is the likeliest acceleration error. It is mitigated by the + twins. +3. **The range bound is conservative.** Nearly tangent halfspaces stay undecided for many levels, + which costs boxes but never correctness. +4. **`Capacity` comes from OCCT**, not from the shipped solid. +5. **Geant4 has no direct equivalent.** A pure union of cells with all-interior halfspaces maps to + `G4MultiUnion`. The general case, with complemented halfspaces, needs a `G4VSolid` subclass + mirroring this class. +6. **Boundary-gap declines stay declined.** These are parts whose convex pieces are not cells of + the carrier arrangement. Splitting at every carrier crossing would fix them. This class makes + the resulting larger cell counts affordable. diff --git a/Detectors/CADSupport/doc/reference/Roadmap.md b/Detectors/CADSupport/doc/reference/Roadmap.md new file mode 100644 index 0000000000000..0b44637a1b859 --- /dev/null +++ b/Detectors/CADSupport/doc/reference/Roadmap.md @@ -0,0 +1,97 @@ +# Roadmap — deferred work + +This is the list of work that has been decided on but deferred. Each item states what is missing +and why it waits. Nothing here is scheduled. + +Open defects and limitations are in `../known-issues.md`; proposals that are not yet decided are in +`../ideas.md`. + +## Performance + +- **An approximate `Safety`.** `O2BVHSurfaceSolid::Safety` is always exact. Stopping the BVH descent + early, with a guaranteed underestimate, would make it cheaper. It waits because a looser safety + costs extra transport steps, which only a transport-level measurement can price. +- **Safety caching.** A per-thread cache of recent safety answers would combine with the above. + It waits on that measurement too. +- **Per-candidate trim cost.** Once the BVH has pruned, `Contains` spends most of its time in the + trim test, winding and `Curve2D::closestPoint` on B-spline polylines. The options are an exact + Bézier-clipping point-in-trim, or cover boxes subdivided in the trim domain so each candidate + carries a shorter wire. It waits because the cover boxes already cut the candidate count; the + per-candidate cost is next. +- **Optional Embree BVH engine.** It waits on Embree entering the software stack. The BVH should + sit behind an interface thin enough to swap the engine, and Embree must stay optional because + the SIMD situation differs on aarch64. +- **Ahead-of-time specialised kernels.** A converted geometry is static, so the converter could + emit per-part code with constants folded and no virtual dispatch. It waits until exact + shared-edge trims give the inner loops a small closed form. Templates over patch archetypes are + the cheaper first step. +- **A device (GPU) port of `O2FlatCSG`.** The data are already PODs in four arrays and the BVH + traversal uses an explicit stack. The remaining work is fixed-size scratch arrays instead of + `thread_local` vectors, a device BVH traversal, and a float or mixed-precision + `EvalHalfspace`. It waits on a decision about which kernel mix a device port should optimise. +- **A device port of `O2BVHSurfaceSolid`.** It needs a rewrite of the representation: the + virtual `BoundedSurface` hierarchy flattened to a tagged POD, pooled trim curves, and a + fixed-capacity hit buffer. It waits behind the `O2FlatCSG` port. + +## Coverage + +- **Free-form surfaces.** Genuine B-spline carriers are the largest remaining coverage gap. The + work is an iterative ray/surface intersector: Bézier clipping, or a BVH of Bézier sub-patches + with Newton refinement. Its benefit over a fine mesh is small, so it must be weighed against the + tessellated fallback before it is started. +- **Non-iso trims on recognised quadrics.** A NURBS face recognised as a quadric is refused when a + boundary edge is a slanted or curved cut in the recognised frame. Fixing this needs a numeric + re-fit of that edge in (phi, h). +- **Torus recognition** in the surface recogniser. The CSG path's Tier 0 already recognises tori. +- **Exact shared-edge trims.** Both faces of a shared edge should derive their trims from one object + per `TopoDS_Edge`. That removes the one-sided trim sliver and makes the rim band exact. + Sidecar v3 already carries the edge identity for the closure verdict. +- **Exact arrangement cells for trims.** This is a research-grade route to parts that neither + tier represents today. +- **The default decomposition cell budget.** `--max-cells` raises it per run. Before moving the + default, the decomposition time at higher budgets has to be measured over the deep-boolean parts. +- **Boundary-gap declines.** Splitting at every carrier crossing instead of at trusted concave edges + would convert them. It is a change to `decompose.py` with its own risk. +- **Direct `TGeoShape` → `O2FlatCSG` emitter.** It would give one flat device representation for a + whole geometry. Primitives map by template. A `TGeoCompositeShape` maps by pushing complements + down into DNF, which blows up unless redundant bounding halfspaces of subtracted tools are dropped + and empty cells are pruned with `HalfspaceRange`. The conjecture that drilled holes collapse to a + single halfspace is unverified. +- **Pcon, Pgon and Xtru round-trip bench.** Pick specimens from the Run 3 geometry, export them + with `O2_TGeoToCAD.py`, convert them back, and score the result against the source `TGeoShape`. + +## Meshing + +- **Separate linear and angular precision.** `--mesh-prec` sets both the linear and the angular + deflection, and in practice the angular one dominates. It waits on a per-volume precision + scheme, which the next item needs anyway. +- **Precision by physics relevance.** Linear deflection would be set per volume from the distance + to the interaction point or from |η|. Two cautions apply. Mesh validity is not monotone in + precision, so each volume has to be validated on its own. For far-field volumes, the acceptance + criterion should be the capacity error rather than the chordal deviation. +- **Mesh healing.** A mesh can be invalid, not just inaccurate, and chordal accuracy does not + detect that. + +## Navigation and assemblies + +- **Assembly-level transport under `TGeoNavigator`.** `assemblyOracle.py` exists; the navigator + side and a leak counter do not. It waits for the Geant integration test, which exercises the + whole geometry. +- **A face-adjacency lookup for CAD-native geometry.** Adjacent CAD parts share faces explicitly, + which could replace the per-step search among siblings with a lookup. It is unmeasured. +- **Carving with an assembly daughter.** `--carve-mothers` cannot subtract an assembly daughter. + The fix is to fuse its placed leaves into the cutter. Some mothers also fail to carve when their + daughters consume them completely. +- **A `TGeoOCCTSolid`.** OCCT itself as a shape, either as the fallback of last resort or as an + in-process oracle. It waits on checks of OCCT's thread safety and of the memory cost of resident + B-reps. +- **Overlap repair at the STEP level.** It is mechanically possible with `BRepAlgoAPI_Cut`, but + which part yields is a modelling decision per assembly. It has low priority because + `TGeoNavigator` tolerates overlaps. +- **Parity on non-manifold input.** Such parts are reported `NonManifold` and answered by vote. + The open decision is whether to reject them at `CloseShape`. + +## Tools + +- **Live event display.** Run o2-sim in service mode with warm workers and tap MCStepLogger or the + O2HitMerger channel. The batch replay comes first. diff --git a/Detectors/CADSupport/doc/reference/SolidNavigationHarness.md b/Detectors/CADSupport/doc/reference/SolidNavigationHarness.md new file mode 100644 index 0000000000000..d54496d59db9e --- /dev/null +++ b/Detectors/CADSupport/doc/reference/SolidNavigationHarness.md @@ -0,0 +1,141 @@ +# Solid navigation harness + +`o2-bench-cadsupport-solid-harness` validates and times the navigation of the CAD-derived shapes +part by part.

This +guide is about crossing that gap automatically — taking an engineering model as it comes out of the +design office and turning it into something particles can be simulated through, all the way to hits +you can plot. + +The usual way of crossing that gap is to read the drawings and write the geometry again by hand, in +C++, volume by volume. That works, and most of ALICE was built this way, but it is slow, it is easy +to get subtly wrong, and every time the engineers move a bracket the translation has to be redone. +For a detector that is still being designed — which is exactly the situation during an upgrade study +— the hand-written geometry is out of date almost as soon as it is written. + +So instead we convert the CAD file directly. You export the assembly as STEP, run one converter over +it, and you get a ROOT macro that builds the geometry. From there a small JSON file tells `o2-sim` to +load that macro and place it in the ALICE world. Nothing is recompiled at any point, so the loop from +a new CAD revision to a new simulation takes minutes rather than weeks. + +Getting the geometry in is only half of it, though. A shape that particles fly through is a passive +obstacle; to do physics you want it to *record* something. The second half of this guide is therefore +about the external-detector mechanism, which lets you declare parts of your imported geometry +sensitive and have them write hits — again with no detector class and no rebuild.

For anything metre-scale you should be careful, +because the cost grows quickly with size — the default `0.1` applied to a two-metre sphere has +produced a **22.9 GB** output directory.

Everything the oracle gate measures is a *single-shot* +/// query: from a sampled point, how far to the surface. A transport loop is different in kind -- +/// step, land *on* the boundary, step again from there -- and that is where geometry navigation +/// actually fails: zero-length steps, ping-ponging on a face, a particle that enters and never +/// exits, a crossing found twice, a step that overshoots into the next volume. None of those can +/// be expressed as a disagreement on `distout` from an interior sample, so the existing gate is +/// structurally blind to all of them. This benchmark shoots a structured parallel-beam raster +/// through a part and produces, per ray, the ORDERED CROSSING LIST -- the sequence of entry/exit +/// distances -- by stepping, two independent ways, and compares the lists (not aggregates) +/// against OpenCascade. +/// +/// TWO STEPPING MODES, and the reason both exist: +/// (a) `shape` -- a direct shape-API loop: Contains() to establish the starting state, then +/// alternating DistFromOutside()/DistFromInside(), advancing the point, until +/// the ray leaves the raster window. Depends on nothing but the shape. +/// (b) `nav` -- the real TGeoNavigator: the part placed in a TGeoVolume inside a minimal +/// world, transported with FindNextBoundaryAndStep(). The production path. +/// If (a) and (b) disagree, that isolates *the shape* from *the navigator* immediately; with only +/// (b) one cannot tell which of the two lied. Both are always reported. +/// +/// THREE-STAGE ROUND TRIP, mirroring the oracle gate: +/// 1. `--dump-rays D` writes D/xrays_.json: the raster window and every ray. +/// 2. `xrayOracle.py` answers exactly those rays from the part's .brep, in OpenCascade, +/// into D/crossings_.json. +/// 3. `--ref-crossings D` steps both modes over the same rays and scores the lists. +/// The rays are written and read rather than regenerated on both sides for the same reason the +/// sample sets are: a comparison is only evidence if both sides answered the same question. +/// +/// NOT REQUIRED: a tessellated mesh. The raster is structured and deterministic, so unlike +/// `generateSamples()` nothing here rejection-samples through `O2Tessellated`.

A name covering several +definitions is emitted as `name`, `name#2`, ... and recorded as `nameDisambiguation`. + +Mother solids are exported uncarved, so every part is the shape the TGeo author +wrote and compares directly with `TGeoShape::Capacity()`. `--carve-mothers` +subtracts the placed daughters for a CAD-facing export. + +Units: TGeo is cm, STEP is written in mm, so every length and translation is +scaled by 10. + +Usage +----- + O2_TGeoToCAD.py INPUT.root OUTPUT.step [options] + O2_TGeoToCAD.py --self-test + + --report FILE per-volume JSON report (default: .report.json) + --top VOLNAME start from this volume instead of the TGeoManager top + --include-name PAT only convert volumes whose name matches this glob + (their ancestors are still emitted as assemblies) + --no-mother-bodies omit the `__body` component of volumes with daughters + --skip-top-body omit only the top volume's own solid (the `cave` box) + --carve-mothers subtract placed daughters from each mother solid + --dedup-world expand the tree per occurrence and drop any placement of a + volume that coincides exactly with another placement of the + same volume (see "coincident placements" below) + --no-verify skip the per-definition BRepGProp capacity check + --no-step build and report, but do not write the STEP + --quiet + +Coincident placements +--------------------- +The default export reproduces a volume placed twice at the same world transform, +which `O2_CADtoTGeo.py` refuses. `--dedup-world` expands the tree per occurrence +and drops every repeated (definition, world transform); the key is the definition, +as in `O2_CADtoTGeo.py`. + +Reflections +----------- +A STEP placement is a proper rigid motion.

For every cosmic this device stores the TPC tracks of both legs, the raw TPC clusters attached to them, all raw TPC clusters +/// in a road around each leg (gaps, split pieces, delta electrons; clusters attached to other tracks are flagged), the ITS / TOF / TRD +/// hits of the legs' matched tracks and along roads in these detectors, and per TF the quantities of the TPC transformation. +/// +/// Road: each leg's helix is propagated through all pad rows of all sectors on its TPC side, in the frame of its own time0 (the frame +/// in which its clusters are consistent). Points on the other side of the leg's closest approach to the beam line belong to the other +/// leg and are skipped. The predicted real (y, z) is mapped to nominal coordinates with the inverse correction, and clusters with +/// nominal coordinates within the corridor width of the predicted point (distance perpendicular to the track) are taken. The other TPC +/// side is searched only when the time of the cosmic is known (z-continuity time of legs on opposite sides with a small error, or a TOF +/// time); a CE-crossing leg's own frame already covers both sides. Parts of a leg nearly parallel to the pad rows (|snp| >= 0.8 in the +/// sector frame, e.g. around a closest approach to the beam line inside the TPC, where the track runs along one pad row) cannot be +/// reached row by row: there the helix is followed in steps of path length and the rows within the road width of each point are searched. +/// +/// TOF tag: all TOF clusters close to the outward extrapolation of the legs within the cosmic's time window are candidates; the top / +/// bottom pair whose time difference matches the muon's flight along the helix (HitTOFFlight) gives the cosmic its TOF time. The same +/// search in the impossible order (bottom hit first) only finds accidental pairs and is kept as QA of the flag's background. +/// +/// Roads in the other detectors (--road-detectors): TRD tracklets close to the outward extrapolation of the legs and ITS clusters close +/// to the trajectory near the beam line, within the time window of the cosmic (the TOF time if there is one, else the matcher's time, +/// which is precise for TPC-only legs on opposite sides; otherwise the time window of the legs, with a correspondingly loose z cut). +/// They are flagged as found on the road; hits of the legs' matched global tracks are flagged as matched. In the ITS the road keeps per +/// half of the cosmic and layer the cluster closest to the trajectory, in the inner barrel (dense with collision clusters near the beam +/// line) the 5 closest, best first. Cosmics sharing >= 30 % of their TPC clusters with a better one (a leg split into two TPC tracks) are +/// flagged as duplicates, nothing is removed. +/// +/// Polish: a cosmic with a TOF time and TPC-only legs is refitted at that time (as in the matcher: muon mass, energy loss along the +/// flight); one-side legs then have their real z, hence the right material, which the matcher's TPC time cannot always give. +/// +/// Besides the matcher's and the polished track, only raw detector data are stored (TPC ClusterNative, ITS compact clusters + patterns, +/// raw TOF time, TRD tracklet words); calibrations, the cluster dictionary and the geometry are applied offline. +/// +/// --debug-tree writes cosmics_collector_debug.root for test runs: tree "cosmics" with one entry per cosmic, its matching and timing +/// quantities and vectors per detector: cl* every stored TPC cluster transformed (local x, y, z in the frame used by the road, zCos in the +/// common frame of the cosmic's time, global gx, gy), road* the predicted track points of each leg (same frames; roadFrame 0 / 1 own +/// / cosmic's time frame row by row, 2 / 3 the same along the low-angle walk), its* the +/// local (with the ITS road also global) coordinates of the ITS clusters, tof* the raw and calibrated TOF time and the cluster position, +/// trd* the road tracklets and their residuals.

Those are reported as +ambiguous rather than assigned arbitrarily, and `makeSurfaceIndex()` throws. One surface +per sensor is enforced in both modes. + +## The Gen3 geometry description + +`Detectors/Upgrades/ALICE3/ACTS/config/gen3_geometry_config.json` carries everything +geometry-specific: sensor name globs, region boundaries, per-subsystem clustering +tolerances, passive material structures and the pinned volume IDs. All lengths in mm. + +It is tuned for the layout `run_test.sh` generates — verified against an o2-sim geometry of +that layout: the sensor globs cover every sensitive volume family (and correctly exclude +`FT3Sensor_Inactive_*`), `*EOSCard*` matches the 504 end-of-stave volumes, the passive +cylinder radii and half-lengths match the real support volumes, and the resulting +volume/layer/surface table is identical to the one actsO2's reference geometry produces. + +One known imprecision, inherited and present for both geometries: `TRK_MID_CarbonSupport` +is declared with `halfZ = 1420` while the real `TRK_MID_CARBONSUPPORT` volume has +`dz = 1410 mm`. It only affects the z-extent of that passive layer's material receiver. + +## Material + +Gen3 construction takes no `IMaterialDecorator`, so an ACTS JSON material map is applied +afterwards via `setMaterialMapFile()`. Material maps are keyed on +`Acts::GeometryIdentifier`, so a structural change to a builder invalidates existing +maps; the manager raises rather than silently producing a material-free geometry. + +## Checking a geometry + +`Detectors/Upgrades/ALICE3/ACTS/macros/run_test.sh` does the whole thing: it runs +`o2-sim-serial-run5` with the ALICE 3 layout the ACTS chain is developed against, then +builds the tracking geometry from the result and checks every TRK chip against its ACTS +surface. Run it from a scratch directory — `o2-sim` writes into `$PWD`: + +```bash +mkdir -p /tmp/acts && cd /tmp/acts +bash /Detectors/Upgrades/ALICE3/ACTS/macros/run_test.sh +``` + +The geometry description it needs is shipped in this package +(`Detectors/Upgrades/ALICE3/ACTS/config/gen3_geometry_config.json`, installed to +`$O2_ROOT/share/Detectors/Upgrades/ALICE3/ACTS/config/`) and matches the layout the script +generates. Set `GEN3_CONFIG` to point at a different geometry's config. + +Knobs: `nEvents`, `generator`, `modules`, `GEN3_CONFIG`, `SKIP_ALIGNMENT`. The last one +defaults to 1 because `o2-sim` finishes by fetching alignment from CCDB, which needs a +valid alien token and aborts without one — after the geometry file has already been +written. The ACTS geometry is built from the ideal geometry, so skipping it costs nothing. + +The macro `CheckActsTrackingGeometry.C` can also be run on its own against an existing +`o2sim_geometry.root`; it prints the volume/layer/surface table, which is the authority for +the `(volume, layer)` keys that digitisation and seeding configurations use. It needs ACTS, +Eigen and `$O2_ROOT/include` on `ROOT_INCLUDE_PATH` — `run_test.sh` sets that up. diff --git a/Detectors/Upgrades/ALICE3/ACTS/interface/CMakeLists.txt b/Detectors/Upgrades/ALICE3/ACTS/interface/CMakeLists.txt new file mode 100644 index 0000000000000..0a9d583305151 --- /dev/null +++ b/Detectors/Upgrades/ALICE3/ACTS/interface/CMakeLists.txt @@ -0,0 +1,36 @@ +# Copyright 2019-2020 CERN and copyright holders of ALICE O2. +# See https://alice-o2.web.cern.ch/copyright for details of the copyright holders. +# All rights not expressly granted are reserved. +# +# This software is distributed under the terms of the GNU General Public +# License v3 (GPL Version 3), copied verbatim in the file "COPYING". +# +# In applying this license CERN does not waive the privileges and immunities +# granted to it by virtue of its status as an Intergovernmental Organization +# or submit itself to any jurisdiction. + + +o2_add_library(ACTSInterface + TARGETVARNAME targetName + SOURCES src/TrackingGeometryManager.cxx + src/SurfaceIndexMap.cxx + src/MagneticFieldAdapter.cxx + PUBLIC_LINK_LIBRARIES O2::DetectorsBase + O2::DetectorsCommonDataFormats + O2::Field + O2::Framework + ROOT::Geom + Acts::Core + Acts::PluginRoot + Acts::PluginJson) + +target_compile_definitions(${targetName} PUBLIC O2_WITH_ACTS) + +o2_add_library(ALICE3ACTS + SOURCES src/TrkTGeoBlueprintBuilder.cxx + PUBLIC_LINK_LIBRARIES O2::ACTSInterface + nlohmann_json::nlohmann_json) + +o2_target_root_dictionary(ALICE3ACTS + HEADERS include/ALICE3ACTS/TrkTGeoBlueprintBuilder.h + ) diff --git a/Detectors/Upgrades/ALICE3/ACTS/interface/include/ACTSInterface/ITrackingGeometryBuilder.h b/Detectors/Upgrades/ALICE3/ACTS/interface/include/ACTSInterface/ITrackingGeometryBuilder.h new file mode 100644 index 0000000000000..705dfdc18150a --- /dev/null +++ b/Detectors/Upgrades/ALICE3/ACTS/interface/include/ACTSInterface/ITrackingGeometryBuilder.h @@ -0,0 +1,79 @@ +// Copyright 2019-2026 CERN and copyright holders of ALICE O2. +// See https://alice-o2.web.cern.ch/copyright for details of the copyright holders. +// All rights not expressly granted are reserved. +// +// This software is distributed under the terms of the GNU General Public +// License v3 (GPL Version 3), copied verbatim in the file "COPYING". +// +// In applying this license CERN does not waive the privileges and immunities +// granted to it by virtue of its status as an Intergovernmental Organization +// or submit itself to any jurisdiction. + +/// +/// \file ITrackingGeometryBuilder.h +/// \brief Detector-agnostic interface for building an Acts::TrackingGeometry from TGeo +/// \author Paolo Butti +/// + +#ifndef ALICEO2_ACTS_ITRACKINGGEOMETRYBUILDER_H +#define ALICEO2_ACTS_ITRACKINGGEOMETRYBUILDER_H + +#include +#include + +#include "Acts/Geometry/GeometryContext.hpp" +#include "Acts/Geometry/TrackingGeometry.hpp" +#include "Acts/Surfaces/SurfacePlacementBase.hpp" + +#include "ACTSInterface/SurfaceIndexMap.h" + +class TGeoManager; + +namespace o2::acts +{ + +/// Everything a builder produces, kept together because the parts have a +/// lifetime dependency on each other. +struct TrackingGeometryOutput { + /// Non-const so the manager can still decorate it with material before + /// handing it out; it is published as shared_ptr afterwards. + std::shared_ptr geometry; + + /// Detector elements backing the sensitive surfaces. + /// + /// Acts::TrackingGeometry does NOT own these: Acts::Surface keeps a raw, + /// non-owning back-pointer to its placement (Surface::surfacePlacement()). + /// Destroying this store while \a geometry is alive is a dangling-pointer bug, + /// so it must be kept for at least as long as the geometry. + std::vector> elementStore; + + /// Sensor <-> surface lookup.

The example above shows a single iteration with 11 layers and it is **not** optimized. + +### Restricting CA seeding to selected layers + +Each entry in `trackingparams` accepts the following optional parameters for both hit and cluster input: + +| Parameter | Default | Meaning | +| --- | --- | --- | +| `SeedingLayers` | `0` | Bit mask of layers used to build CA tracklets and cells. Zero uses all active layers. | +| `InactiveLayerMask` | `0` | Bit mask of inactive layers, excluded from CA seeding and from the effective track-length calculation. | +| `MaxHoles` | `0` | Maximum number of missing seeding-layer hits allowed within a seed. | +| `HoleLayerMask` | `0` | Bit mask of seeding layers on which holes are allowed. | +| `StartLayerMask` | `127` | Bit mask of layers from which CA seed extraction may start; it does not select the layers used to build the CA. | + +Masks are integer values with bit `i` corresponding to layer `i` (numbering starts at zero). `SeedingLayers` is intersected with the active layers within `NLayers`; at least three seeding layers are required. Layers excluded from seeding do not count as holes. Active layers outside `SeedingLayers` can still receive clusters through the track follower. + +For example, add these fields to an 11-layer iteration to seed on layers 3 through 10 and then extend tracks inward to layers 0 through 2: + +```json +"SeedingLayers": 2040, +"StartLayerMask": 2047, +"TrackFollower": "inward" +``` + +Keep `NLayers` and the per-layer geometry and error arrays describing the full detector. `MinTrackLength` still applies to the final track; the minimum number of seeding clusters is capped at the number of selected seeding layers. Omitting the new parameters preserves the existing defaults. + +## Complete Workflow Example + +### 1.

The parser interprets the file differently depending on the active `TRKBase.layoutMLOT` setting (`kCylindrical`, or `kSegmented`/`kSimplifiedRealistic` which share the same syntax). + +### General Syntax Rules +* **Separators:** All columns **must** be separated by a single TAB (`\t`). Using spaces will result in a parsing error. +* **Comments:** Any line starting with a forward slash (`/`) is treated as a comment and ignored. +* **Layer Count:** The parser reads valid lines sequentially. The first valid line corresponds to Layer 0, the second to Layer 1, and so on. +* **Material Budget Mode:** All layer definitions accept an optional `matBudgetMode` parameter at the end of the line (e.g., `0` = Thickness, `1` = X2X0). If omitted, it defaults to `Thickness`. + +### 1. Cylindrical Layout (`kCylindrical`) + +When `TRKBase.layoutMLOT=kCylindrical` is used, each layer requires a minimum of 3 parameters to define the `TRKCylindricalLayer`. + +* **Format:** `rInn` \t `length` \t `thick` \t `[optional_mode]` +* *(Note: `rInn`, `length`, and `thick` map directly to the constructor arguments for the cylindrical layer, typically corresponding to Radius, Length, and Thickness).* + +**Example for `kCylindrical`:** +```text +/ Configuration for kCylindrical layout - ALICE3 TRK +/ rInn length thick [optional_mode] +7.0 127.985 0.1 +9.0 127.985 0.1 +12.0 127.985 0.1 +20.0 127.985 0.1 +30.0 127.985 0.1 +45.0 255.9 0.1 +60.0 255.9 0.1 +80.0 255.9 0.1 +``` + +### 2. Segmented / Simplified-Realistic Layout (`kSegmented`, `kSimplifiedRealistic`) + +Both layouts use the same configuration-file syntax (only the OT geometry implementation differs). Each layer requires a minimum of 5 base parameters to define the geometry. The parser distinguishes between Middle Layers (ML) and Outer Layers (OT) based on the sequential layer index. + +* *(Note: The 5 base parameters map directly to: Inner Radius (`rInn`), Thickness (`thick`), Tilt Angle (`tiltAngle`), Number of Staves (`nStaves`), and Number of Modules per stave (`nMods`)).* + +**Middle Layers (ML) - Indices 0 to 4** +The first 5 valid lines are parsed as `TRKMLLayer` objects. These layers **require** a 6th parameter for the staggering offset (`stagOffset`). +* **Format:** `rInn` \t `thick` \t `tiltAngle` \t `nStaves` \t `nMods` \t `stagOffset` \t `[optional_mode]` \t `[optional_rInnRow]` \t `[optional_phiOffset]` +* Layers 3 and 4 are staggered: one stave out of two sits at `rInn`, the others are shifted by `stagOffset`. By default the even staves are at `rInn`; `rInnRow` = 1 puts the odd staves there instead, i.e. stave 0 in the shifted row. In the flipped layer 3 the `rInn` row is the outer one and the shift points inwards, so there `rInnRow` = 1 puts stave 0 in the inner row; in layer 4 in the outer row. To give `rInnRow`, the mode column must be written too. +* `phiOffset` (degrees, counterclockwise, default 0) rotates the whole layer about the beam axis; each stave keeps its tilt. It requires the mode and `rInnRow` columns. + +**Outer Layers (OT) - Indices 5 and above** +From the 6th valid line onwards, lines are parsed as OT layer objects (`TRKOTLayer` for `kSegmented`, `TRKOTLayerRealistic` for `kSimplifiedRealistic`). These layers do **not** have a staggering offset. The optional mode parameter shifts to the 6th column. +* **Format:** `rInn` \t `thick` \t `tiltAngle` \t `nStaves` \t `nMods` \t `[optional_mode]` +* *(Note: for `kSimplifiedRealistic`, `nStaves` is the number of staves per ring and must be even; if it is 0 the count is derived from the radius as the smallest one giving the required neighbour overlap.)* + +**Example for `kSegmented`:** + +```text +/ Configuration for kSegmented layout - ALICE3 TRK +/ --- ML LAYERS (Indices 0 to 4) --- +/ rInn thick tilt nStaves nMods stagOffset [optional_mode] +7.0 0.01 11.2 10 11 0.0 1 +9.0 0.01 11.9 14 11 0.0 1 +12.0 0.01 11.4 18 11 0.0 1 +20.0 0.01 0.0 26 11 1.17 1 +30.0 0.01 0.0 38 11 0.89 1 +/ +/ --- OT LAYERS (Indices 5 to 7) --- +/ Outer layers do NOT have stagOffset. +/ rInn thick tilt nStaves nMods [optional_mode] +45.0 0.01 0.0 32 22 1 +60.0 0.01 0.0 42 22 1 +80.0 0.01 0.0 56 22 1 +``` + +## Additional options for forward disks + +Furthermore, there are more options in the case of stave segmentation -- for only OT or both. The user can set to cut the staves exactly on the nominal inner radii (true by default), and outer radii (false by default) of the disks. This exists since (planned) placements of sensors & staves often protrude out of the nominal radii to be more able to cover the nominal disk area. In addition, it is possible to draw reference circles (`TRKBase.drawReferenceCircles`) in root for the stave segmented layouts for both the inner (red) and outer (blue) radii. This is off by default, yet can be toggled if the user wants to see how tight the tiling is to the nominal radii -- for visualisation purposes only. + +## Simplified-Realistic OT geometry (`kSimplifiedRealistic`) + +`kSimplifiedRealistic` keeps the ML layers identical to `kSegmented` but replaces the solid-silicon OT modules with a more detailed, but still simplified, description (`TRKOTLayerRealistic`). It affects the **OT barrel only** — the forward disks are independent of `layoutMLOT` and are configured as described above. All tunable dimensions live in [`Specs.h`](./base/include/TRKBase/Specs.h) (`constants::OT`); values that depend on others are computed in the source. + +The geometry specification is based on [ALICE3 OT WP1 Material (26.06.2025)](https://indico.cern.ch/event/1562183/contributions/6580808/attachments/3093672/5480049/ALICE3_OT_WP1_Material_260625.pdf). + +**Module** — a flush stack about the chip mid-plane: cold plate (carbon fibre), 8 pure-silicon chips (2 in φ × 4 in z, dead zones facing the outer module edges), FPC (Kapton+Cu), one ZIF connector centred on a short edge, SMD capacitors over the chip footprints (skipping any under the connector), and two mounting brackets on the cold plate. + +**Stave** — two module rows overlapping in φ (so each row's dead zone is covered by the other row's sensor) and offset in r by `rowRadialStagger`, plus a cooling pipe between them. The rows straddle the stave frame origin, so a stave placed on the barrel circle is tangent at its own centre: every row-to-row radial step in the barrel — inside a stave and between neighbours — is then the same `rowRadialStagger`, in every layer. + +**End-of-stave card** — one readout PCB per stave (`constants::OT::eosCard`), mounted past the last module at the outer z end, coplanar with the two rows: a 120 × 80 mm, 1.5 mm board carrying four copper planes spread symmetrically through the thickness, the remainder FR4. The copper is what sets the card material budget: at the default 122 µm per plane the card is **4.0 % x/X₀** for a track crossing it perpendicularly (copper 3.40 %, FR4 0.60 %). It is tunable through `TRKBase.otEosCardCuThickness`, which changes only the copper/FR4 split inside the fixed 1.5 mm envelope, so the card dimensions and the layer envelopes stay put and only the radiation length moves. The cards reach |z| ≈ 141 cm, just short of the OT barrel service disk, which places them at |η| ≈ 1.84–1.88 on the innermost OT layer and |η| ≈ 1.27–1.32 on the outermost — inside the tracking acceptance, so they matter for forward-disk performance. + +**Barrel** — each layer is built in **four parts**: two z-half-barrels (±η), each split azimuthally into two 180° halves. Both η half-barrels are cut on the **same vertical plane** (x = 0), so the region where the vertical beam-pipe supports run is free of staves over the whole barrel (the supports themselves are not in the geometry). Neighbouring staves overlap (≥ 1 mm active double-coverage); at the cut plane the two azimuthal halves instead leave a gap wide enough for the separation wall plus `barrelWallClearance` on each side. The default paving uses OT radii 442, 620 and 820 mm with 30, 42 and 56 staves per ring (15/21/28 per quarter barrel); L9 and L10 follow the mechanical CAD, L8 is placed as close in as the 1 mm active-overlap requirement allows for 30 staves. This gives 8.4-9.0 mm of border-to-border neighbour overlap in the stave plane. Each module's FPC extends 2.1 mm beyond the chips for wire bonding (`constants::OT::fpc::wireBondMargin`). The cooling pipe faces the larger radius on the inner two OT layers and the smaller radius on the flipped outer layer. + +**Separation walls** — the quarter barrels are closed on every side but the one carrying the end-of-stave cards (`TRKServices::createOTBarrelWalls`, `kPeacockv1` + `kSimplifiedRealistic`): radially by the ML/OT and outer carbon shells, azimuthally by a rectangular carbon fibre wall in the cut plane, and at mid-rapidity by a half disk at z = 0, one per quarter barrel. + +Both walls run **continuously** from one shell to the other: each OT layer envelope is a tube with a slot cut along the vertical cut plane *and* one at z = 0 (`TGeoCompositeShape`), so the walls pass through the layers instead of being interrupted by them, and what is left of each envelope is the four quarter barrels. The slots clear the walls by `barrelWallSlotMargin`; the staves stay `barrelWallClearance` away from them. + +Only the outer shell is load bearing, so it is the only 4 mm wall; the ML/OT shell is 2 mm and the side panels and mid-rapidity disks default to 2 mm via `TRKBase.otBarrelWallThickness`. + +The OT services (cables/cooling bundles, cold plates) are built by `TRKServices` for all layouts via `TRKBase.layoutSRV`. + + diff --git a/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/CMakeLists.txt b/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/CMakeLists.txt new file mode 100644 index 0000000000000..89775e22ed8d0 --- /dev/null +++ b/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/CMakeLists.txt @@ -0,0 +1,23 @@ +# Copyright 2019-2020 CERN and copyright holders of ALICE O2. +# See https://alice-o2.web.cern.ch/copyright for details of the copyright holders. +# All rights not expressly granted are reserved. +# +# This software is distributed under the terms of the GNU General Public +# License v3 (GPL Version 3), copied verbatim in the file "COPYING". +# +# In applying this license CERN does not waive the privileges and immunities +# granted to it by virtue of its status as an Intergovernmental Organization +# or submit itself to any jurisdiction. + +o2_add_library(TRKBase + SOURCES src/GeometryTGeo.cxx + src/AlmiraParam.cxx + src/TRKBaseParam.cxx + src/SegmentationChip.cxx + PUBLIC_LINK_LIBRARIES O2::DetectorsBase) + +o2_target_root_dictionary(TRKBase + HEADERS include/TRKBase/AlmiraParam.h + include/TRKBase/GeometryTGeo.h + include/TRKBase/TRKBaseParam.h + include/TRKBase/SegmentationChip.h) diff --git a/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/include/TRKBase/AlmiraParam.h b/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/include/TRKBase/AlmiraParam.h new file mode 100644 index 0000000000000..53d4792f7c2a5 --- /dev/null +++ b/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/include/TRKBase/AlmiraParam.h @@ -0,0 +1,68 @@ +// Copyright 2019-2020 CERN and copyright holders of ALICE O2. +// See https://alice-o2.web.cern.ch/copyright for details of the copyright holders. +// All rights not expressly granted are reserved. +// +// This software is distributed under the terms of the GNU General Public +// License v3 (GPL Version 3), copied verbatim in the file "COPYING". +// +// In applying this license CERN does not waive the privileges and immunities +// granted to it by virtue of its status as an Intergovernmental Organization +// or submit itself to any jurisdiction. + +#ifndef O2_TRK_ALMIRAPARAM_H +#define O2_TRK_ALMIRAPARAM_H + +#include + +#include "CommonConstants/LHCConstants.h" +#include "CommonUtils/ConfigurableParam.h" +#include "CommonUtils/ConfigurableParamHelper.h" +#include "TRKBase/Specs.h" + +namespace o2 +{ +namespace trk +{ + +struct AlmiraParam : public o2::conf::ConfigurableParamHelper { + // This should be part of geometryTGeo + static constexpr size_t kNLayers = constants::VD::petal::nLayers + constants::ML::nLayers + constants::OT::nLayers + constants::MLOTDisks::nLayers;

neutron-equivalent fluence + +The scoring volume dimensions are defined directly in: + + scoring_g4_alice3.in + +Only the number of bins in R and Z is overridden at run time. + + +SCORING BINNING +--------------- + +Default binning: + + R: 640 bins + Z: 1000 bins + +The defaults correspond to: + + /score/mesh/nBin 640 1000 1 + +The top-level: + + scoring_g4_alice3.in + +is NEVER modified by the run. + +Instead, `01_run.sh` copies it into: + + Simulation_files/work/scoring_g4_alice3.in + +and modifies only that temporary copy with the requested number of bins. + + +CHANGE CONFIGURATION +--------------------------- +The detector configuration and running options are in 01_run.sh + +Search the lines: + +CONFIG_KEYS="MIDBase.mLayout=0; Alice3PassiveBase.mMagnetLayout=MagThickRadius; FT3Base.layoutFT3=kSegmented; IOTOFBase.enableBackwardTOF=false; IOTOFBase.enableForwardTOF=false; G4.g4scoring=true; G4.g4fluenceweight=true; G4.fluenceWeightFile=$WORK_DIR/rd50_niel.csv;

+ +And modify what you need (note: running with FT3 option FT3Base.layoutFT3=kSegmented) + + +RECOMMENDED GENERAL COMMAND +--------------------------- + +Run the complete workflow (here 15000 events, but slow): + + python3 simulation.py all --events 15000 --bins-r 640 --bins-z 1000 + +This performs: + + prepare + | + v + run + | + v + check + | + v + clean + +If `--seed` is omitted, a new time-based random seed is generated automatically for every run. + +The bins are referred to Z from -500 to 500 cm and radius from 0 to 320 cm. + + +CUSTOM BINNING +-------------- + +For example: + + python3 simulation.py all --events 15000 --bins-r 800 --bins-z 1200 + +This keeps the same physical scoring volume but changes the mesh granularity. + + +DIRECT SHELL EXECUTION +---------------------- + +Default binning and automatic seed: + + ./01_run.sh 15000 + +Fixed seed: + + ./01_run.sh 15000 123456 + +Custom scoring binning: + + SCORING_BINS_R=800 \ + SCORING_BINS_Z=1200 \ + ./01_run.sh 15000 + +Custom scoring binning with fixed seed: + + SCORING_BINS_R=800 \ + SCORING_BINS_Z=1200 \ + ./01_run.sh 15000 123456 + + +FIRST TEST +---------- + +Before a full production run, a small test can be performed with: + + python3 simulation.py all --events 10 --bins-r 640 --bins-z 1000 + +The seed is automatically randomized unless `--seed` is explicitly supplied. + + +OUTPUT ORGANIZATION +------------------- + +All temporary files generated by O2 are written under: + + Simulation_files/work/ + +The final scoring output is copied to: + + Simulation_files/ALICE3.txt + +The final geometry is copied to: + + Simulation_files/ALICE3_geometry.root + + +FINAL OUTPUT AFTER CLEAN +------------------------ + +After a successful cleanup: + + Simulation_files/ + ├── ALICE3.txt + └── ALICE3_geometry.root + +All other files generated during the simulation are deleted. + +The permanent top-level files: + + rd50_niel.root + rd50_niel.csv + +are never removed by the cleanup procedure. + + +RE-RUNNING +---------- + +If Simulation_files already contains ALICE3 results, the workflow stops +before overwriting them and prints a warning. + +If you want to keep the previous results, rename or move the folder, for example: + + mv Simulation_files Simulation_files_old + +Then run the simulation normally. + +If instead you want to discard the previous results and replace them: + + python3 simulation.py all --events 15000 --bins-r 640 --bins-z 1000 --force + +ANALYSIS +-------- + +Produce geometry_points.csv from the root geometry file: + + root -l -b -q make_geometry_csv.C + +By default it takes the file ./Simulation_files/ALICE3_geometry.root +Source, destination R and Z range can be changed using the arguments of the function. + +A geometry_points.csv with the reference geometry is copied anyway with the setup. + +Run the Geant4 TID/NIEL analysis with: + + python3 analyze_geant.py + +The script reads the simulation output from Simulation_files/ALICE3.txt and produces

Instead it learns, like TTreeCache: a reader asks +for the same tables in every DF. + +- `NativeAODFileSystem::planFor(path)`: when a tree of a new DF is asked for, a + new `ReadPlan` is made with every basket of the trees read in the previous DF + registered, plus this tree.

Read calls reading every tree (per basket before / with +the plan / ROOT): hy_3993289/0065 5023 / 2121 / 2379; hy_1318738 86424 / 1232 / +1164; AO2D_019 4191 / 497 / 789; LHC24ar 71799 / 2273 / 3783. Bytes read +0.07% +(merged gaps). In DPL (`analysis-histograms` on LHC24ar, a few tables): +8852 → 1209 read calls, ROOT 444; about 19 merged ranges per DF, because the +requested baskets are interleaved with those of unread trees. They go out in one +`readvInto` per DF, which is one vectored request for a remote source; locally +it is still one pread each. + +Cost, locally: wall time within 0-2% of pread without the plan. Max RSS grows by +about one DF of compressed bytes (macOS, `MallocLargeCache=0`: hy_1318738 +310 → 349 MiB, AO2D_019 364 → 444, LHC24ar 311 → 360), the same order as +ROOT's 50 MB TTreeCache. With the macOS allocator cache on, max RSS is higher +(378, 599, 435 MiB): it keeps freed large blocks resident; glibc returns them. + +## XRootD source (milestone 5, step 2) + +`XRootDByteSource` (root://, roots://, xroot://, xroots://), built when O2 finds +XRootD (optional in O2); otherwise those URLs get an IoError, so `auto` falls +back. Links only libXrdCl. After opening it asks the data server for its +kXR_readv limits (`readv_ior_max`, `readv_iov_max`), as TNetXNGFile does, +keeping XrdCl's defaults (2097136 bytes, 1024 chunks) when it does not answer. +`readvInto` sends ranges up to the chunk limit in vectored reads and larger ones +in plain reads of at most 8 MiB, asynchronously, in rounds of at most +`Options::remoteInFlightBytes` (32 MiB), waiting for each round; a short or +failed reply is an IoError. `readCalls()` counts requests sent. + +Until 2026-11-05 a whole plan went out at once, with plain reads of up to +64 MiB. On the Grid, at ORNL reading Poznan EOS (slow transatlantic link), the +native reader then failed 2-6x more often than ROOT, mostly with "Operation +expired": requests sharing the link took longer than XRD_REQUESTTIMEOUT (150 s +in the ALICE environment). Smaller requests and the in-flight limit keep each +request well within it. + +Tested against a local server (Homebrew xrootd 6.2.0, `all.export ~/src/data +r/o`): byte-identical with both readers over root:// on hy_3993289/0065, +hy_1318738 and LHC24ar (7.8 GB).

They are parsed only when asked for, so a TTree the + native reader cannot parse still fails only if requested. About 30 kB per + DF on LHC24ar and hy_1318738, 2 kB on hy_3993289. +- The entry count of a last basket missing from `fBasketEntry` is computed + from the branch's entries; the decoder checks it against the basket header. + The header read stays as fallback. + +Requests per DF are now 4 sequential round trips: directory record, key list, +TTrees, data (a few requests in flight).

It works on its own copy +of `RootFile` over the same source, so `RootFile` is never shared across +threads. When the reader reaches that DF, the keys, trees and plan are adopted; +a lookahead for another DF, or one which failed, is dropped (the normal path +redoes the work and reports errors). Not started for the first DF of a file, +which has not shown yet which trees are read. + +The next DF is the one after the current in the read order DPL uses: +`DataInputDescriptor` passes its `listOfTimeFrameNumbers` through +`AODInputFile::setReadOrder()`. `RootFile::dataFrames()` could not stand in for +it: with a parentFiles map, DataInputDirector sorts by parent file with an +unstable sort, so DFs of the same parent can come in a different order. + +Also: `readStringMap()` results are cached (parentFiles was read twice at open). + +Over root://localhost, every tree, median of 3 (wall s): + +| File | root | native, no prefetch | native | --threads 4: no prefetch / prefetch | +|---|---|---|---|---| +| hy_3993289/0065 | 0.89 | 0.56 | 0.36 | 0.56 / 0.36 | +| hy_1318738 | 3.43 | 3.24 | 2.61 | 1.24 / 0.92 | +| LHC24ar | 7.75 | 7.11 | 5.38 | 2.91 / 2.30 | + +Over root:// native now runs at the speed of local pread (LHC24ar 5.48 s). +Cost: one more DF of compressed bytes (max RSS +34 MiB on hy_1318738, +81 MiB on +LHC24ar). Requests are about the same as without it (151 vs 130, 283 vs 283); +in DPL (analysis-histograms, LHC24ar) 380 vs 319, with identical results. + +## AliEn lookup (milestone 5, step 5) + +`alien://` files: `gridReplicas(lfn)` (AODInputFile.cxx, which may use ROOT) +sends `access read ` through `gGrid`, as `TJAlienFile::Open` does, and +turns each replica into `root:////?&authz=`. Files inside +an archive (`#member`, on the LFN or the replica) are refused, so `auto` falls +back to ROOT. `openNativeAOD()` reads the replicas, in the order AliEn +proposes, through `ByteSource::openReplicas()` (`FailoverByteSource`): the +first replica which opens is read; a read which fails with an IoError, at any +point of the file, is retried on that replica, reopened, up to +`Options::readRetries` (2) times per replica with a doubling delay from +`retryDelay` (2 s), and then continues on the next replica of the same size. +Only IoErrors are retried: a format problem is the same on every replica. Each +retry and change of replica is logged. ROOT only moves to another replica when +opening fails, so this makes the native reader more robust than ROOT on flaky +storage. DPL's reader and the comparison tool both open files through it. +The file keeps its LFN as name: what DataInputDirector compares, what goes +with derived output, and what monitoring reports, with `se=` and +`open_time=` as for TJAlienFile. `XRootDByteSource` uses the full URL only to +open; its `url()` and error messages leave out the query, so the access +envelope does not reach logs or outputs. + +From a Mac at CERN, token from alien-token-init: +- hy_3993289/0065 (alien:///alice/cern.ch/user/a/alihyperloop/jobs/0399/...): + byte-identical with ROOT (TJAlienFile), 264 DFs / 792 trees. +- LHC24ar, first 10 DFs, `--bench`: root 25.15 s, 603 requests, 2.70 s user, + 382 MiB; native 19.93 s, 71 requests, 1.25 s user, 522 MiB. Both read about + 408 MB: bandwidth bound (16 vs 20 MB/s from CERN EOS), native keeps the + connection busier thanks to the lookahead. +- DPL, `o2-testworkflows-analysis-histograms --aod-file alien://.../LHC24ar/...AO2D.root`: + AnalysisResults.root identical (5 histograms) with root, native and auto. + Requests 444 (root) vs 380 (native), 628.5 vs 629.1 MB read. The open + line reads `lfn=alien://...,size=2630072561,se=ALICE::CERN::EOS,open_time=0.1`, + and no `authz` appears in the log. Wall times (root 49.4 s, native 48.7 s, + auto 35.2 s with the same native code) vary by 13 s from run to run over the + WAN: a timing comparison needs interleaved repeats, or a Hyperloop test. + +## HTTP(S) source (milestone 5, step 6) + +`HttpByteSource` (http://, https://), libcurl, public servers only (no +authentication yet). The size comes from a HEAD request; reads are ranged GETs, +ranges above 16 MiB split so that the pieces go out in parallel. `readvInto` +sends all its GETs at once on a curl multi handle: multiplexed on one +connection with HTTP/2 (`CURL_HTTP_VERSION_2TLS` by default, `httpVersion`), +otherwise over at most `httpConnections` (4) connections. Connections, TLS +sessions and DNS are shared by all the calls on a source (a curl share +handle), so the lookahead and the reader can fetch at the same time. +Redirects are followed; `X509_CERT_DIR` sets the CA path. A reply must be a 206 +with exactly the bytes asked for: a server which ignores the range is caught at +the first extra byte and refused ("the server ignored the byte range"), so +`auto` falls back to ROOT rather than downloading the whole file. + +Tested: `o2-aod-native-inspect https://root.cern/files/h1/dstarmb.root` (HEAD and +ranges over public HTTPS); Python's http.server, which ignores ranges, is +refused. Against a local range-capable test server (HTTP/1.1, single ranges), +native over HTTP vs ROOT on the local file (the tool takes +`=`): byte-identical on hy_3993289/0065, hy_1318738 and +LHC24ar, also with --threads 4. hy_1318738, localhost: 3.14 s without +prefetch, 2.65 s with, 0.97 s with --threads 4 (root:// 3.24, 2.61, 0.92). + +Public HTTP, alimonitor train test data (LHC15o Run 2 converted, ROOT 6.24, +zlib, 1.19 GB, http://alimonitor.cern.ch/train-workdir/testdata/LFN/alice/data/2015/LHC15o/000246392/pass2/PWGZZ/Run3_Conversion/320_20220701-0813/AOD/153/AO2D.root): +byte-identical with ROOT on a local copy (15 DFs, 360 trees, 3.7 GB +serialised). Bandwidth bound at about 26 MB/s, as wget (44.0 s for the file): +native 47.8 s without prefetch, 45.0 s with, 46.1 s with --threads 4; 3.2 s of +user CPU. This ROOT build cannot read http:// at all (the TWebFile plugin entry +fails in ROOT 6.40, and there is no Davix), so for these files `auto` has no +fallback and the native reader is the only way. + +## Building and testing + +In O2: built with the rest of Framework (aliBuild).
