Also the insert callback is called with the entries starting form the end of the buffer. -An easy extension can be to reverse the order of the inserts, meaning that the entries are read from the beginning. - -.SH EXAMPLES -.SS ReverseParser example -.EX -using SomeParser = ReverseParser; -SomeParser parser; -std::vector frames; -parser.parse(ptr, size, - [] (const typename SomeParser::HeaderType& h) { - // check the header - return true; - }, - [] (const typename SomeParser::TrailerType& t) { - // check the trailer - return true; - }, - [] (const typename SomeParser::TrailerType& t) { - // get the size of the frame including payload - // and header and trailer size, e.g. payload size - // from a trailer member - return t.payloadSize + SomeParser::totalOffset; - }, - [&frames] (typename SomeParser::FrameInfo& info) { - frames.emplace_back(info); - return true; - } - ) -.EE - -.SS ForwardParser example with frame consisting of header and payload -.EX -using SomeParser = ForwardParser; -SomeParser parser; -std::vector frames; -parser.parse(ptr, size, - [] (const typename SomeParser::HeaderType& h) { - // check the header - return true; - }, - [] (const typename SomeParser::HeaderType& h) { - // get the size of the frame including payload - // and header and trailer size, e.g. payload size - // from a header member - return h.payloadSize + SomeParser::totalOffset; - }, - [&frames] (typename SomeParser::FrameInfo& info) { - frames.emplace_back(info); - return true; - } - ) -.EE - -.SH BUGS, CONTRIBUTIONS -Please add an issue to -.UR https://github.com/AliceO2Group/AliceO2/issues -.UE - -.SH SEE ALSO -.UR https://github.com/AliceO2Group/AliceO2/blob/dev/Algorithm/include/Algorithm/Parser.h -.UE diff --git a/Algorithm/include/Algorithm/BitstreamReader.h b/Algorithm/include/Algorithm/BitstreamReader.h deleted file mode 100644 index 0a112183ab5ef..0000000000000 --- a/Algorithm/include/Algorithm/BitstreamReader.h +++ /dev/null @@ -1,290 +0,0 @@ -// 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 BITSTREAMREADER_H -#define BITSTREAMREADER_H - -/// @file BitstreamReader.h -/// @author Matthias Richter -/// @since 2019-06-05 -/// @brief Utility class to provide bitstream access to an underlying resource - -#include -#include - -namespace o2 -{ -namespace algorithm -{ - -/// @class BitStreamReader -/// @brief Utility class to provide bitstream access to an underlying resource -/// -/// Allows to access bits of variable length, supports integral types and also -/// bitsets as target type.

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.

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|`.

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/README.md b/Common/DCAFitter/README.md index bbb079d144748..e385378d10caf 100644 --- a/Common/DCAFitter/README.md +++ b/Common/DCAFitter/README.md @@ -2,7 +2,7 @@ \page refDetectorsVertexing DCAFitter /doxy --> -## DCAFitterN +# DCAFitterN Templated class to fit the Point of Closest Approach (PCA) of secondary vertex with N prongs.

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. These development packages are **not** dependencies of the C++ header or the portable O2 tests. + +```python +import importlib +import examples.tracktools_synthetic_5d_demo as demo +importlib.reload(demo) + +adfSynthetic = demo.make_synthetic_track_geometry_adf(n_tracks=1000) +adfCounts = demo.make_synthetic_row_counts_adf(adfSynthetic) + +sel = ('(input_mode=="5D_full")&(method=="H")&' + '(state_status==0)&(rows_status==0)&' + '(observable=="Available")&(stack!="TPC")') + +adfCounts.draw( + "count:dSector85", selection=sel, + type="scatter", color="qpt", marker="o", + facet_by=["isPrimary", "stack"], ncols=4, + auto_title=True, share_y="none" +) +``` + +![Geometrically available TPC rows versus dSector85, split by TPC stack and primary/secondary truth](docs/figures/trackgeometry_synthetic_5d_available_rows.png) + +*Figure — Synthetic TrackGeometry illustration.* The vertical axis `count` is the **number of geometrically Available pad rows**, not observed clusters; the horizontal axis `dSector85` is the **fractional sector coordinate at R = 85 cm** (not an edge distance); colour encodes signed `q/pT` [(GeV/c)⁻¹]. 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 BVH over boxes that cover the patches accelerates every +navigation query. It is the exact alternative to a tessellated mesh for parts whose faces are all +analytic. + +The converter `O2_CADtoTGeo.py` produces it with `--exact-surfaces auto|required`.

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`.

A loop made only of lines loads + through `AddPlanarSurface`. Any arc or B-spline edge routes the face through + `AddCurvedPlanarSurface`. +- **Quadrics and tori** carry no wire block when the trim is the scalar rectangle in `params`. + Otherwise the block holds one outer wire and optional holes in the patch's (u, v) domain + (section 1.1). The converter writes such a block only when the trim does not fill the (u, v) + rectangle. +- **Curved pcurves on quadrics** (circles, ellipses, Béziers, B-splines) are written as B-splines + whose poles have been pushed through the affine (u, v) → (phi, h or theta) map. This is exact, + because a B-spline is closed under affine maps. +- **Wire closure.** Consecutive edge endpoints must meet within the join band as a 3D length. The + band is the declared model tolerance, or 1e-6 cm when that is smaller or not stated. The reader + and the kernel apply the same rule. + +Rules for the edge block: + +- The boundary-edge list is written wire by wire in the file's wire order, which is + `BRepTools_WireExplorer` order — the same order as the trim curves. The reader permutes it into + the kernel's order (outer wire first). +- A face without a wire block still lists its edges, unanchored. +- Closure is decided by identity only if every surface of the solid states its edges. +- The reader refuses an `edgeId` outside the edge table when `nModelEdges` is stated. +- Each boundary-edge entry is packed without padding, 5 bytes (`uint32` + `uint8`): the writer emits + it with `struct.pack("` writes the +per-face classification without changing the output. `--dump-brep` writes the OCCT BREP of each +exact leaf, in cm, for the OCCT oracle. + +- **Stored analytic faces.** Plane, cylinder, cone, sphere and torus faces extract directly. Quadric + and torus pcurves are converted to lines or to affine-mapped B-splines. `inner_wall` follows + `TopAbs_REVERSED`. +- **Recognised faces.** A B-spline, Bézier, extrusion or revolution face is tested against plane, + sphere, cylinder and cone models. It is accepted only at a relative gap below 1e-9 + (`--recognize-surfaces exact`, the default). Its trim is rebuilt by sampling the 3D boundary + edges in the recognised frame. Every edge must then be iso-parametric: a rim or a generator. +- **Trim curves.** A B-spline trim edge that is exactly a line (collinear poles) or a circle + (relative residual below 1e-9) is stored as that curve. +- **Planar faces** accept line, circle, ellipse, B-spline and Bézier edges. Ellipses and Béziers are + converted to B-splines. +- **Model tolerance and edge table.** The model tolerance is the largest BRep tolerance of the + shape, in cm.

The surface recogniser has no torus model. +- **The trim tie-break is one-sided.** A hit inside a patch's on-boundary band counts as inside the + trim, so a B-spline-trimmed patch can overhang its true seam by up to about `kBSplineFlatness`. + `Contains` detects this and re-shoots. `DistFromOutside`, `DistFromInside` and `ComputeNormal` + use such hits without a check. +- **Rim sampling is fixed at `kArcSamples` per turn.** Rim distances below the chord sagitta, + r(1 − cos(π/24)), cannot be resolved.

Inside means +sign · (√((ρ − R)² + z²) − r) ≤ 0, with ρ the distance from the axis and z the coordinate along it. +The canonical form gives both the quartic for rays and the exact signed distance for the range +bound. No reference direction is stored, because a phi limit is a plane of the same cell. + +A cell is `FlatCSGCell { int first; int count; double volume; }`, a range of the halfspace array. + +**The plane row must use a unit normal, b = n/2.** Any positive rescaling describes the same +halfspace, but only a power-of-two rescaling keeps the accelerated distances bit-identical to +their `_Loop` twins. A cell box face often lies on one of the cell's own axis-aligned planes. The +BVH then reaches that parameter as a slab bound, and the interval clipping reaches it as a +quadratic root. Both give the same double only when the scale is a power of two. The test +`the_accelerated_distances_track_their_twins_when_a_plane_is_rescaled` measures the cost of a ×3 +rescale. + +### 3.2 Fidelity + +The shipped solid is the intersection of the halfspaces the faces carry, everywhere. The tree +path, by contrast, is exact only inside its padded window. + +### 3.3 Sign convention + +The material side combines the carrier's orientation (a plane's normal is already flipped for +`TopAbs_REVERSED`) with the `side` field from `census.halfspace_side`. An inverted halfspace still +yields a solid, so the error would be silent. The self-test of `cadsupport.emit` therefore checks +every flat cell against `_cell_leaf`'s padded-primitive conjunction on a sample of points. + +## 4. The sub-cell BVH + +### 4.1 Why boxes, not cells + +The AABB of a long diagonal, curved or L-shaped cell is mostly empty. The BVH primitives are +therefore sub-boxes of cells, each with its own list of still-active halfspaces. + +### 4.2 The build + +For each cell, `CloseShape` starts from the cell box given by `SetCellBBox` and splits it +recursively at the median of the longest axis. 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.

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.

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.

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.

For each +constant it gives the value and the reason. It also states the rules the constants follow, and the +known limits of the scheme. + +## 1. Rules + +1. **Compare like with like.** A tolerance is compared only against a quantity of the same + dimension. Parametric separations on a quadric mix radians and centimetres, so they are first + converted to a 3D length through the surface's first fundamental form (section 2). +2. **Normalise algebraic guards.** Where a guard asks whether a discriminant, resolvent or + derivative is zero, the problem is normalised to be dimensionless first, and the threshold is a + multiple of the machine epsilon. Where an exact structural condition can decide instead, it is + used and no constant exists. +3. **Prefer the model's own tolerance.** When the source model declares a tolerance (sidecar + version 2 or later), it replaces the fallback constants, but never goes below the extractor + floor. +4. **Lower bounds stay lower bounds.** Every guard on a safety or pruning bound errs towards a + smaller distance. A too-small safety costs a step; a too-large one lets the navigator cross a + wall. + +## 2. The parametric metric + +`BoundedSurface::parametricMetric(uv, gUU, gUV, gVV)` gives the first fundamental form at `uv`. A +displacement (du, dv) then spans the length sqrt(gUU·du² + 2·gUV·du·dv + gVV·dv²). + +| surface | gUU | gUV | gVV | +| --- | --- | --- | --- | +| plane, curved plane | axisU·axisU | axisU·axisV | axisV·axisV | +| cylinder | r² | 0 | 1 | +| cone | r(h)² | 0 | 1 + k², with k = dr/dh | +| sphere | (R sin θ)² | 0 | R² | +| torus | (R + r cos φ_tube)² | 0 | r² | + +The form varies over the domain, so it is evaluated at the point of interest. gUU vanishes at a +sphere pole and at a cone apex; code that divides by it must handle zero. The wire-join checks in +the kernel and in the sidecar reader both go through this metric. + +## 3. Kernel constants (`src/BoundedSurface.h`) + +| constant | value | reason | +| --- | --- | --- | +| `kTolerance` | 1e-9 cm | Generic length tolerance. It sets the on-surface test and the floor of the on-boundary band for exact curves. | +| `kAreaTolerance` | 1e-18 | Parametric area below which a wire is degenerate. | +| `kRayTolerance` | 1e-9 cm | Minimum positive ray parameter for parity hits. | +| `kIntersectionTolerance` | 1e-7, relative | Two hits are one cluster if \|t1 − t2\| ≤ 1e-7·max(1, \|t1\|, \|t2\|). It is absolute below 1 cm. | +| `kClosureQuantum` | 1e-7 cm | Vertex lattice for the per-chord half-edge counters. These counters are diagnostic only and decide no verdict. | +| `kWireJoinTolerance` | 1e-6 cm | Wire-join band, as a 3D length: the extractor's endpoint precision. `wireJoinToleranceFor(t)` returns max(t, 1e-6) for a declared model tolerance t. | +| `kBSplineFlatness` | 1e-5, parametric | Chord flatness of the B-spline polyline. It is also the on-boundary band floor for B-spline trims, because the polyline is the boundary as far as winding is concerned. | +| `kRimMatchTolerance` | 1e-6 cm | Rim-matching tolerance when the model states none. Same origin as `kWireJoinTolerance`. | +| `kBVHBoxTolerance` | 1e-3 cm | Widening of every BVH cover box before outward float rounding. It must dominate every navigation length tolerance, so that a hit or on-surface point is never pruned. | +| `kQuarticEpsilon` | 32·DBL_EPSILON | Zero test for the normalised quartic solver (section 7). It is a running-error allowance for sums of three or four products of coefficients bounded by 1, not a fitted value. | +| `kArcSamples` | 24 per turn | Chord count for display meshes and rims. It must be divisible by 4 so that quarter-turn-rotated frames sample one shared circle at the same points. | +| `angularTolerance(r)` | kTolerance / max(r, kTolerance) | Angle corresponding to a `kTolerance` arc length at radius r. | +| `kCoverChunkAngle` | π/4 | Widest angular span of one cover box. A chunk's box stays within 1 − cos(π/8) (about 8%) of its arc, and a full sweep costs eight boxes. | +| `kContourQuadratureOrder` | 20 | Gauss-Legendre order of the Green's-theorem capacity integral for wire-trimmed quadrics. | +| `kContourMaxSpanU` | π/4 | Widest u-span of one contour quadrature piece. | +| `kSharedEdgeSamples` | 33 | Samples per edge in the shared-edge deviation measurement. | +| `kMaxSmoothTurn` | 0.52 rad (about 30°) | Rim vertices turning by more than this are corners and are left out of the sampling-noise estimate.

This stays far below `kBVHBoxTolerance`, so the winning patch is still visited. | +| safety anchors | 24 | Display vertices used to seed the nearest-patch traversal. | +| re-shoot directions | 5, majority 3 | Golden-spiral directions for the containment vote. Three directions were too few; thirteen gained little over five. | +| float ray bound | + FLT_EPSILON·\|t\| | `truncateRoundUp`: a float `tmax` is never shorter than the double bound it stands for. | + +## 5. O2Tessellated pruning constants (`Detectors/Base/src/O2Tessellated.cxx`) + +`O2Tessellated` stays in `Detectors/Base` (it is also used by `Steer/O2MCApplication`), but its BVH +ray queries follow the same pruning idea as the solid and flat-CSG traversals: lowering the ray's +own `tmax` on a hit prunes the rest of the traversal, and the constants below state how far that may +go without dropping a nearer facet. + +| constant | value | reason | +| --- | --- | --- | +| `kFacetBoxPad` | 0.001 cm | Outward pad of every BVH leaf box, so the facet it stands for lies strictly inside it. | +| `kMaxPruneScale` | `kFacetBoxPad · 2²⁴ / 8` | Largest sum of \|origin\| and \|box\| below which lowering the ray bound on a hit cannot drop a nearer facet: float rounding of ray, box and traversal then stays well inside `kFacetBoxPad`. `pruneLimit()` subtracts both from this to get the per-query cutoff. | + +## 6.

Same value and reason as `kBVHBoxTolerance`. | +| `kSafetyBoundShare` | `O2BVHAssembly.cxx` | 1/3 | Share of a node's squared box distance that bounds a daughter's `Safety`. `TGeoBBox::Safety` returns the largest per-axis gap, which is at least the Euclidean distance over √3. | +| box-distance guard | `O2BVHAssembly.cxx` | ×(1 − 1e-12) | Same purpose as the solid's copy (section 4): scales the squared point-to-box distance down, three orders above its rounding error, so it stays a lower bound for `Safety`. | +| `kMaxRootsPerHalfspace` | `O2FlatCSG.cxx` | 4 | A quartic has at most four real roots. | +| `kMaxCubifySplits` | `O2FlatCSG.cxx` | 10 | Per-path ceiling on splits that only equalise aspect ratio. | +| `fSplitDepth` | `O2FlatCSG.h` | 4 | Sub-cell subdivision depth cap, chosen for query cost on the shipped parts. | +| `fMinBoxFraction` | `O2FlatCSG.h` | 0.05 | Minimum box size as a fraction of the part diagonal. | +| `kPadFactor` | `O2FlatCSG.cxx` | 64·DBL_EPSILON | Pads a halfspace range bound by the magnitude accumulated when evaluating it, so the bound survives cancellation. | +| debug bbox probe | `O2FlatCSG.cxx` | 1e-6 · diagonal | Outward offset of the 5×5 face samples that check a cell box contains its cell (debug builds). | +| `kFlipProbe` | `O2FlatCSG.cxx` | 1e-6 cm | Offset either side of a sampled boundary point. `GetPointsOnSegments` keeps the point only if `Contains` differs across it. | +| linear-solve cutoff | `O2FlatCSG.cxx` | \|α\| ≤ 1e-14·(\|β\|+\|γ\|) | A ray whose quadric coefficient α is this small relative to β and γ is solved as hitting a plane instead of a quadratic; the discarded root would lie beyond about 1e6 cm, outside any ALICE geometry. | +| `depthTolerance` | `O2OverlapCheck.h` | 1e-6 cm | A containment shallower than this is a shared boundary, not an overlap. | +| `residualTolerance` | `O2OverlapCheck.h` | 1e-6 cm | A sampled boundary point farther than this from its own solid's boundary is not evidence about anything and is discarded. | +| default boundary band | `O2SolidHarness.cxx` | 1e-3 · bounding-box diagonal | Fallback used when the harness config leaves `boundaryBand` unset, sizing the near-boundary sample band from the part's own extent. | + +## 7. The quartic solver + +`solveQuarticReal` (ray and torus) first substitutes x = s·y. Here s is the Cauchy root bound +max(|b|, |c|^½, |d|^⅓, |e|^¼) of the monic quartic, rounded up to a power of two. Every +coefficient then lies in [−1, 1], and the branch guards compare against `kQuarticEpsilon`. + +Scaling by a power of two is exact in binary floating point, so the normalisation changes no +rounding and no answer; only the guards change. An unrounded Cauchy bound does not have this +property. + +Two guards use structural conditions instead of a constant: + +- The Newton polishing step is taken if it is finite and no longer than 2, the root bound in + normalised units. +- `solveDepressedCubic` branches on P ≥ 0 (Cardano) versus P < 0 (trigonometric). No threshold is + needed, and P = Q = 0 returns 0 through Cardano. + +## 8. Bands built from the constants + +- **On-boundary band of a trim.** `CurveWire::boundaryBand` is the larger of `kTolerance` + (converted to parametric units through the metric's largest scale) and the wire's + `representationTolerance()`. That is `kBSplineFlatness` if any curve is a B-spline, else 0. + Winding and distance use the same polyline. A point inside the band is classified `Boundary` and + resolved as inside the trim. The hit is flagged `onTrimBoundary`, and `Contains` re-shoots when + a counted crossing carries the flag. +- **Wire join.** The 3D gap between consecutive endpoints must not exceed + `wireJoinToleranceFor(modelTolerance)`. The reader and the kernel apply the same rule. +- **Rim matching.** A chord is matched when another face's chord lies within + `rimEpsilon + own sagitta + partner sagitta`. `rimEpsilon` is the model tolerance, or + `kRimMatchTolerance`. The non-manifold test uses `rimEpsilon` alone, because at a corner a third + face legitimately comes within a chord length. +- **Rim sampling floor.** The sagitta of a rim chord is estimated from the turn angle, + (chord/2)·tan(turn/4), not from the vertex offset. A box corner would otherwise read as + sampling noise. + +## 9.

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.
