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 6b89207279fe0..dfe9b6e515e9f 100644 --- a/Common/DCAFitter/GPU/cuda/CMakeLists.txt +++ b/Common/DCAFitter/GPU/cuda/CMakeLists.txt @@ -20,6 +20,9 @@ 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 diff --git a/Common/DCAFitter/include/DCAFitter/DCAFitterN.h b/Common/DCAFitter/include/DCAFitter/DCAFitterN.h index 2641dec84aed9..95248714a72ae 100644 --- a/Common/DCAFitter/include/DCAFitter/DCAFitterN.h +++ b/Common/DCAFitter/include/DCAFitter/DCAFitterN.h @@ -12,7 +12,8 @@ /// \file DCAFitterN.h /// \brief Defintions for N-prongs secondary vertex fit /// \author ruben.shahoyan@cern.ch -/// For the formulae derivation see /afs/cern.ch/user/s/shahoian/public/O2/DCAFitter/DCAFitterN.pdf +/// For the original derivation see /afs/cern.ch/user/s/shahoian/public/O2/DCAFitter/DCAFitterN.pdf +/// The AI-assisted readme is in DCAFitterN_derivation.md #ifndef _ALICEO2_DCA_FITTERN_ #define _ALICEO2_DCA_FITTERN_ @@ -28,17 +29,37 @@ namespace vertexing { ///__________________________________________________________________________________ -///< Inverse cov matrix (augmented by a dummy X error) of the point defined by the track +///< Inverse covariance matrix of the point defined by the track struct TrackCovI { - float sxx, syy, syz, szz; + // Independent elements of the symmetric 3D information matrix + // H^T Cyz^{-1} H.

It represents a +CAD solid by its exact boundary: a set of analytic surface patches (plane, cylinder, cone, sphere, +torus), each trimmed to its face. 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.

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. The per-chord sagitta band also underestimates the + disagreement between two independently flattened polylines of one curve. +- **Two faces of one shared edge carry independent trims.** Edge identity makes the closure + verdict structural, but the geometry of the two trims is still per face. +- **`Safety` can be loose** for wire-trimmed patches and for trimmed spheres and tori. +- **Per-candidate cost** is dominated by the trim test (winding and closest point on the curve + polylines), not by the root solve.

Decomposition + +`tools/cadsupport/decompose.py` splits a part into cells: + + start from the part's connected solids; + while a piece has a trusted concave (or mixed) edge: + extend the carrier of one of the edge's faces to a full surface; + split the piece with BRepAlgoAPI_Splitter; + a piece with no trusted concave edge is one cell. + +Connected solids come first, because a part with no concave edges can still be several disjoint +pieces. The split pieces must sum to the part's volume within `VOLUME_REL_TOL` (1e-6), or the part +declines. + +The budgets apply to the whole working set: + +| budget | default | override | +| --- | --- | --- | +| `PART_MAX_CELLS` | 64 | `--max-cells` | +| `MAX_SPLITS` | 256 | `--max-splits` | +| `TIMEOUT_S` | 60 s | `--decompose-timeout` | + +## 5.

The candidate is an OCCT realisation of + the description. +2. **False-accept guard** (`accept.contains_disagreements`): `BRepAlgoAPI_Cut` can report success + with no solid in either direction. A sampled containment comparison catches that case. +3. **Oracle gate** (`validation/runOracleGate.py`): scores the ROOT realisation of the same + description against the OCCT oracle. +4. **Known source** (`validation/checkKnownSource.py`): scores a shape against the `TGeoShape` it + was exported from, when the model came from TGeo. + +`tools/cadsupport/primitives.py` realises one description twice, with `build_occ()` and +`build_root()`. The symmetric difference and the gate therefore test the same description through +two independent builders. + +## 6.

The depth is always two. It carries +parts that the CSG decomposition splits into cells but that are too deep to ship as a +`TGeoCompositeShape`. A BVH over sub-cell boxes keeps the cost proportional to the halfspaces that +are undecided where the query lands. + +The section numbers are referenced from `test/testFlatCSG.cxx` and `test/runXRayBenchmark.cxx`; +keep them stable. + +## 1. Why it exists + +A union of many cells shipped as a `TGeoCompositeShape` is a deep binary tree of `TGeoBoolNode`s. +Each query recurses into both children of every node, so its cost grows with the whole tree. The +tree path also has to bound each halfspace into a padded native primitive (`_cell_leaf`, sized by +`_CELL_MARGIN`), which equals the cell only near the part. + +`O2FlatCSG` stores the halfspaces themselves. There is no padding and no margin, and the cost +follows the locally undecided halfspaces. + +## 2.

Plane, sphere, cylinder, cone and elliptic cylinder +are all this one block: + +| carrier | A | 2b | c | +| --- | --- | --- | --- | +| plane, unit outward n through p | 0 | n | −n·p | +| sphere, centre p, radius r | I | −2p | \|p\|² − r² | +| cylinder, axis (p, d), radius r | I − ddᵀ | −2Ap | pᵀAp − r² | +| cone, axis (p, d), ref. radius r, k = tan α | I − (1+k²)ddᵀ | −2Ap − 2rk·d | pᵀAp + 2rk(p·d) − r² | +| elliptic cylinder, axes x̂, ŷ, semi-axes a, b | x̂x̂ᵀ/a² + ŷŷᵀ/b² | −2Ap | pᵀAp − 1 | + +A torus (`kTorus`) stores its canonical form (px, py, pz, dx, dy, dz, R, r) in the first eight +slots: centre, unit axis, major and minor radius. 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.

The loader rejects first < 0, count ≤ 0 and + first + count > nHalfspaces. It also rejects an unknown `kind`, a non-finite coefficient and a + torus with a zero axis. +- `volume` is the OCCT volume of the source piece. +- `lo` and `hi` are the cell box passed to `SetCellBBox`: an outer bound owed by the converter. + +Records are packed without padding: 100 bytes per halfspace and 64 bytes per cell. They are read +field by field, because the natural C++ struct pads to 104 bytes. The loader checks the remaining +file length against nHalfspaces·100 + nCells·64 before reading any record, so a truncated or +overlong file is refused. `WriteFlatCSG` refuses a shape that is not closed, because its unset cell +boxes would be written as zeros. + +## 8. The converter side + +The decomposition (`tools/cadsupport/decompose.py`) splits a part into cells at trusted concave +edges. Its budget covers the whole working set of cells, pending pieces and unresolved pieces: +`PART_MAX_CELLS` = 64, `MAX_SPLITS` = 256 and `TIMEOUT_S` = 60 s by default. The converter can raise +all three with `--max-cells`, `--max-splits` and `--decompose-timeout`. + +The flat emitter (`tools/cadsupport/flat.py`) maps each carrier from `_halfspace_carriers` directly +to a quadric or torus block. The flat path has its own budgets, `_PART_MAX_FLAT_CELLS` = 256 and +`_PART_MAX_FLAT_HALFSPACES` = 1024. The tree path keeps `_PART_MAX_LEAVES` = 64. + +Ordering rules: + +- The flat path runs last, after every whole-part matcher, the single-cell reading and the + union-of-cells tree have declined. No part that another tier accepts changes representation. +- A one-piece decomposition keeps the whole-part guards: an all-planar body belongs to the prism + templates and a one-carrier body to the tier-1 templates. The flat path does not overrule them. +- A single cell is admissible in the class and in `primitives.flat_cells`. + +## 9. Open measurements + +- The crossover between flat and composite emission, in cells and in halfspaces. +- The split parameters (depth, minimum box size, cubify budget) against leaf list length, box + count, memory and query cost. +- `Safety` quality against the true distance, since a sound but weak bound costs transport steps. + +## 10. Acceptance + +A flat part ships only if it passes the same tests as any CSG part: the OCCT symmetric difference +within tolerance, the oracle gate, and `checkKnownSource.py` against the source `TGeoShape` when +one exists. The false-accept guard `accept.contains_disagreements` also runs, because +`BRepAlgoAPI_Cut` can report success with no solid in either direction. + +## 11. Risks and limits + +1. **The sign convention** is the likeliest silent error. It is mitigated by the check against + `_cell_leaf`. +2. **The clip-inside-the-box rule** is the likeliest acceleration error. It is mitigated by the + twins. +3. **The range bound is conservative.** Nearly tangent halfspaces stay undecided for many levels, + which costs boxes but never correctness. +4. **`Capacity` comes from OCCT**, not from the shipped solid. +5. **Geant4 has no direct equivalent.** A pure union of cells with all-interior halfspaces maps to + `G4MultiUnion`. The general case, with complemented halfspaces, needs a `G4VSolid` subclass + mirroring this class. +6. **Boundary-gap declines stay declined.** These are parts whose convex pieces are not cells of + the carrier arrangement. Splitting at every carrier crossing would fix them. This class makes + the resulting larger cell counts affordable. diff --git a/Detectors/CADSupport/doc/reference/Roadmap.md b/Detectors/CADSupport/doc/reference/Roadmap.md new file mode 100644 index 0000000000000..0b44637a1b859 --- /dev/null +++ b/Detectors/CADSupport/doc/reference/Roadmap.md @@ -0,0 +1,97 @@ +# Roadmap — deferred work + +This is the list of work that has been decided on but deferred.

It waits because a looser safety + costs extra transport steps, which only a transport-level measurement can price. +- **Safety caching.** A per-thread cache of recent safety answers would combine with the above. + It waits on that measurement too. +- **Per-candidate trim cost.** Once the BVH has pruned, `Contains` spends most of its time in the + trim test, winding and `Curve2D::closestPoint` on B-spline polylines. The options are an exact + Bézier-clipping point-in-trim, or cover boxes subdivided in the trim domain so each candidate + carries a shorter wire. It waits because the cover boxes already cut the candidate count; the + per-candidate cost is next. +- **Optional Embree BVH engine.** It waits on Embree entering the software stack. The BVH should + sit behind an interface thin enough to swap the engine, and Embree must stay optional because + the SIMD situation differs on aarch64. +- **Ahead-of-time specialised kernels.** A converted geometry is static, so the converter could + emit per-part code with constants folded and no virtual dispatch. It waits until exact + shared-edge trims give the inner loops a small closed form. Templates over patch archetypes are + the cheaper first step. +- **A device (GPU) port of `O2FlatCSG`.** The data are already PODs in four arrays and the BVH + traversal uses an explicit stack. The remaining work is fixed-size scratch arrays instead of + `thread_local` vectors, a device BVH traversal, and a float or mixed-precision + `EvalHalfspace`. It waits on a decision about which kernel mix a device port should optimise. +- **A device port of `O2BVHSurfaceSolid`.** It needs a rewrite of the representation: the + virtual `BoundedSurface` hierarchy flattened to a tagged POD, pooled trim curves, and a + fixed-capacity hit buffer. It waits behind the `O2FlatCSG` port. + +## Coverage + +- **Free-form surfaces.** Genuine B-spline carriers are the largest remaining coverage gap. The + work is an iterative ray/surface intersector: Bézier clipping, or a BVH of Bézier sub-patches + with Newton refinement. Its benefit over a fine mesh is small, so it must be weighed against the + tessellated fallback before it is started. +- **Non-iso trims on recognised quadrics.** A NURBS face recognised as a quadric is refused when a + boundary edge is a slanted or curved cut in the recognised frame. Fixing this needs a numeric + re-fit of that edge in (phi, h). +- **Torus recognition** in the surface recogniser. The CSG path's Tier 0 already recognises tori. +- **Exact shared-edge trims.** Both faces of a shared edge should derive their trims from one object + per `TopoDS_Edge`. That removes the one-sided trim sliver and makes the rim band exact. + Sidecar v3 already carries the edge identity for the closure verdict. +- **Exact arrangement cells for trims.** This is a research-grade route to parts that neither + tier represents today. +- **The default decomposition cell budget.** `--max-cells` raises it per run. Before moving the + default, the decomposition time at higher budgets has to be measured over the deep-boolean parts. +- **Boundary-gap declines.** Splitting at every carrier crossing instead of at trusted concave edges + would convert them. It is a change to `decompose.py` with its own risk. +- **Direct `TGeoShape` → `O2FlatCSG` emitter.** It would give one flat device representation for a + whole geometry. Primitives map by template. A `TGeoCompositeShape` maps by pushing complements + down into DNF, which blows up unless redundant bounding halfspaces of subtracted tools are dropped + and empty cells are pruned with `HalfspaceRange`. The conjecture that drilled holes collapse to a + single halfspace is unverified. +- **Pcon, Pgon and Xtru round-trip bench.** Pick specimens from the Run 3 geometry, export them + with `O2_TGeoToCAD.py`, convert them back, and score the result against the source `TGeoShape`. + +## Meshing + +- **Separate linear and angular precision.** `--mesh-prec` sets both the linear and the angular + deflection, and in practice the angular one dominates. It waits on a per-volume precision + scheme, which the next item needs anyway. +- **Precision by physics relevance.** Linear deflection would be set per volume from the distance + to the interaction point or from |η|. Two cautions apply. Mesh validity is not monotone in + precision, so each volume has to be validated on its own. For far-field volumes, the acceptance + criterion should be the capacity error rather than the chordal deviation. +- **Mesh healing.** A mesh can be invalid, not just inaccurate, and chordal accuracy does not + detect that. + +## Navigation and assemblies + +- **Assembly-level transport under `TGeoNavigator`.** `assemblyOracle.py` exists; the navigator + side and a leak counter do not. It waits for the Geant integration test, which exercises the + whole geometry. +- **A face-adjacency lookup for CAD-native geometry.** Adjacent CAD parts share faces explicitly, + which could replace the per-step search among siblings with a lookup. It is unmeasured. +- **Carving with an assembly daughter.** `--carve-mothers` cannot subtract an assembly daughter. + The fix is to fuse its placed leaves into the cutter. Some mothers also fail to carve when their + daughters consume them completely. +- **A `TGeoOCCTSolid`.** OCCT itself as a shape, either as the fallback of last resort or as an + in-process oracle. It waits on checks of OCCT's thread safety and of the memory cost of resident + B-reps. +- **Overlap repair at the STEP level.** It is mechanically possible with `BRepAlgoAPI_Cut`, but + which part yields is a modelling decision per assembly. It has low priority because + `TGeoNavigator` tolerates overlaps. +- **Parity on non-manifold input.** Such parts are reported `NonManifold` and answered by vote. + The open decision is whether to reject them at `CloseShape`. + +## Tools + +- **Live event display.** Run o2-sim in service mode with warm workers and tap MCStepLogger or the + O2HitMerger channel.

It draws: + +- bulk points in the inflated box; +- points within a band of the reference surface; +- points the reference calls inside; +- rays from outside points, half of them aimed at random interior points so that + `DistFromOutside` hit rates stay meaningful; +- rays from inside points. + +**Validation** compares each representation with the reference. Every disagreement is sorted into +one of four bins: + +- within the reference's own band (for the mesh, the chord sagitta); +- a missed surface (a wall missed or tunnelled through; this is never excused); +- unexplained; +- no verdict (the oracle declined). + +The worst offenders are printed with their point and direction, so each one can be reproduced. +`Safety` is checked only against its contract, 0 ≤ safety ≤ true distance, and never compared +between two shapes. + +**Timing** runs each kernel over the same sample order for every representation. A checksum of the +results stops the compiler from removing the calls. The output is ns/call and the ratio between +representations. The run also reports primitive counts, `CloseShape` time and BVH candidate counts. + +**Reliability** of each surface solid is printed per part as a `navigation:` line, and in the JSON +under `navigation`: the reliability state, whether the part is navigable, and the rim and edge +counts. Unnavigable parts are listed again at the end. An accuracy figure for a part that is not +navigable describes an incomplete solid. + +## 4.

Mismatches within the band are + expected. +- **Compare against `O2Tessellated`, never `TGeoTessellated`.** The ROOT class does not implement + navigation and falls back to its bounding box. +- **The `_Loop` cross-check is the correctness guard that does not involve the mesh.** The BVH and + loop paths minimise over the same hits, so any difference is a traversal bug. +- **Seeds are fixed.** A number that cannot be reproduced exactly is not a measurement. +- **Look at the per-part numbers.** The spread between parts is wide, so a median alone hides it. + +## 5.

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. A rim sampled at 24 per turn turns by 15° per vertex. | + +## 4. Solid constants (`O2BVHSurfaceSolid`) + +| constant | value | reason | +| --- | --- | --- | +| `kSurfacePointTolerance` | 1e-11 cm | Distance to its patch within which `GetPointsOnSegments` accepts a projected point. | +| `kDistanceRayTolerance` | −kRayTolerance | Distance queries accept hits from just behind the origin, so that a crossing at the origin is not lost. | +| box-distance guard | ×(1 − 1e-12) | Scales the squared point-to-box distance down, three orders above its rounding error, so it stays a lower bound. | +| anchor seed | d·(1 + 1e-12) + 1e-10 cm | Inflates the upper bound taken from the safety anchors. 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. IO, assembly, overlap-check, harness and flat-CSG constants + +| constant | where | value | reason | +| --- | --- | --- | --- | +| `kSidecarV1FallbackTolerance` | `O2SurfaceSolidIO.cxx` | 1e-6 cm | Model tolerance assumed for a version-1 sidecar. It is the extractor precision; the reader warns when it uses it. | +| `kBoxTolerance` | `O2BVHAssembly.cxx` | 1e-3 cm | Daughter box widening. 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`. That is what makes +/// this instrument runnable on a model whose meshing does not fit in memory. + +#include "RepresentationBench.h" +#include "XRayTransport.h" + +#include "CADSupport/O2SolidHarness.h" +#include "CADSupport/O2BVHSurfaceSolid.h" +#include "DetectorsBase/O2Tessellated.h" +#include "CADSupport/O2FlatCSG.h" +#include "CADSupport/O2SurfaceSolidIO.h" + +#include "TGeoBBox.h" +#include "TGeoManager.h" +#include "TGeoMaterial.h" +#include "TGeoMatrix.h" +#include "TGeoMedium.h" +#include "TGeoNavigator.h" +#include "TGeoNode.h" +#include "TGeoSphere.h" +#include "TGeoTube.h" +#include "TGeoVolume.h" + +#include + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +using json = nlohmann::json; +using namespace o2::cad; +using namespace o2::cad::harness; +using namespace o2::cad::xray; +using namespace o2::cad::bench; +using o2::base::O2Tessellated; + +namespace +{ + +// The xrays_/crossings_ JSON contract shared with Detectors/CADSupport/validation/xrayOracle.py.

For each generated vertex, one of +eight decay channels (combinations of the two transitions' internal-conversion/gamma +modes) is sampled according to branching fractions derived from the transition energies +and internal conversion coefficients (ICC), then the corresponding conversion +electrons/Auger electrons/fluorescence photons ([KrDecayTable](include/TPCSimulation/GeneratorKrDecay.h)) +are emitted as primary tracks. + +Transition energies and ICC values are read at runtime from the installed Geant4 +photon-evaporation data file, `$G4LEVELGAMMADATA/z36.a83` (the environment variable is +set automatically by Geant4's own setup, inherited by any O2 session). If the variable +is unset or the file cannot be parsed, hardcoded fallback values from +`PhotonEvaporation5.7/z36.a83` are used instead and a warning is printed. + +The number of decays generated per event defaults to 1000 and can be overridden via the +`KR_N_PER_EVENT` environment variable. + +## Usage + +`GeneratorKrDecay` is used as an `o2-sim` external generator, via the thin macro +[macro/krGenerator.C](macro/krGenerator.C). `fileName` must resolve to that macro; `$O2path` +below is the path to your O2 source checkout: + +```shell +export KR_N_PER_EVENT=5000 # decays per event; defaults to 1000 if unset +o2-sim -g external -m TPC -n 100 \ + --configKeyValues "GeneratorExternal.fileName=$O2path/Detectors/TPC/simulation/macro/krGenerator.C;GeneratorExternal.funcName=krGenerator();TPCDetParam.UseGeant4Edep=1" +``` + +To change Geant4-related parameters (e.g. `StepFunction`, fluorescence, Auger cascade), +add `G4.configMacroFile=` to `--configKeyValues`. + +`TPCDetParam.UseGeant4Edep=1` is required: it switches `Detector::ProcessHits()` to use Geant4's +own energy deposit directly instead of the default Bethe-Bloch/NA49 sampling, which is what +correctly resolves the Kr-83m decay channels into their discrete energy peaks. diff --git a/Detectors/TPC/simulation/include/TPCSimulation/Detector.h b/Detectors/TPC/simulation/include/TPCSimulation/Detector.h index 507ba992e2715..10ff59360374c 100644 --- a/Detectors/TPC/simulation/include/TPCSimulation/Detector.h +++ b/Detectors/TPC/simulation/include/TPCSimulation/Detector.h @@ -146,6 +146,8 @@ class Detector : public o2::base::DetImpl void PostTrack() override { ; } void PreTrack() override { ; } + void SetSpecialPhysicsCuts() override; + void SetGeoFileName(const TString file) { mGeoFileName = file; } const TString& GetGeoFileName() const { return mGeoFileName; } diff --git a/Detectors/TPC/simulation/include/TPCSimulation/GeneratorKrDecay.h b/Detectors/TPC/simulation/include/TPCSimulation/GeneratorKrDecay.h new file mode 100644 index 0000000000000..3e6c0cca6a3cf --- /dev/null +++ b/Detectors/TPC/simulation/include/TPCSimulation/GeneratorKrDecay.h @@ -0,0 +1,99 @@ +// 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. + +/// \file GeneratorKrDecay.h +/// \brief Generator for 83mKr decays, for TPC gain-map calibration simulation +/// \author Ankur Yadav + +#ifndef ALICEO2_TPC_GeneratorKrDecay_H_ +#define ALICEO2_TPC_GeneratorKrDecay_H_ + +#include "Generators/Generator.h" +#include +#include +#include + +namespace o2::tpc +{ + +/// Table of 83mKr internal-conversion/gamma decay channels and their +/// branching fractions, derived at runtime from Geant4's level/gamma data +/// (falls back to hardcoded PhotonEvaporation5.7/z36.a83 values if +/// unavailable).

The rows straddle the stave frame origin, so a stave placed on the barrel circle is tangent at its own centre: every row-to-row radial step in the barrel — inside a stave and between neighbours — is then the same `rowRadialStagger`, in every layer. + +**End-of-stave card** — one readout PCB per stave (`constants::OT::eosCard`), mounted past the last module at the outer z end, coplanar with the two rows: a 120 × 80 mm, 1.5 mm board carrying four copper planes spread symmetrically through the thickness, the remainder FR4. The copper is what sets the card material budget: at the default 122 µm per plane the card is **4.0 % x/X₀** for a track crossing it perpendicularly (copper 3.40 %, FR4 0.60 %). It is tunable through `TRKBase.otEosCardCuThickness`, which changes only the copper/FR4 split inside the fixed 1.5 mm envelope, so the card dimensions and the layer envelopes stay put and only the radiation length moves. The cards reach |z| ≈ 141 cm, just short of the OT barrel service disk, which places them at |η| ≈ 1.84–1.88 on the innermost OT layer and |η| ≈ 1.27–1.32 on the outermost — inside the tracking acceptance, so they matter for forward-disk performance. + +**Barrel** — each layer is built in **four parts**: two z-half-barrels (±η), each split azimuthally into two 180° halves. Both η half-barrels are cut on the **same vertical plane** (x = 0), so the region where the vertical beam-pipe supports run is free of staves over the whole barrel (the supports themselves are not in the geometry). Neighbouring staves overlap (≥ 1 mm active double-coverage); at the cut plane the two azimuthal halves instead leave a gap wide enough for the separation wall plus `barrelWallClearance` on each side. The stave count is the smallest even number that still meets the required overlap at the layer radius, so the OT radii (440, 615, 793 mm) are chosen at the top of a stave-count band, giving 30/42/54 staves per ring with 1.5-1.9 mm of overlap. The cooling pipe faces the larger radius on the inner two OT layers and the smaller radius on the flipped outer layer. + +**Separation walls** — the quarter barrels are closed on every side but the one carrying the end-of-stave cards (`TRKServices::createOTBarrelWalls`, `kPeacockv1` + `kSimplifiedRealistic`): radially by the ML/OT and outer carbon shells, azimuthally by a rectangular carbon fibre wall in the cut plane, and at mid-rapidity by a half disk at z = 0, one per quarter barrel. + +Both walls run **continuously** from one shell to the other: each OT layer envelope is a tube with a slot cut along the vertical cut plane *and* one at z = 0 (`TGeoCompositeShape`), so the walls pass through the layers instead of being interrupted by them, and what is left of each envelope is the four quarter barrels. The slots clear the walls by `barrelWallSlotMargin`; the staves stay `barrelWallClearance` away from them. + +Only the outer shell is load bearing, so it is the only 4 mm wall; the ML/OT shell is 2 mm and the side panels and mid-rapidity disks default to 2 mm via `TRKBase.otBarrelWallThickness`. + +The OT services (cables/cooling bundles, cold plates) are built by `TRKServices` for all layouts via `TRKBase.layoutSRV`. + + diff --git a/Detectors/Upgrades/ALICE3/TRK/base/CMakeLists.txt b/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/CMakeLists.txt similarity index 100% rename from Detectors/Upgrades/ALICE3/TRK/base/CMakeLists.txt rename to Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/CMakeLists.txt diff --git a/Detectors/Upgrades/ALICE3/TRK/base/include/TRKBase/AlmiraParam.h b/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/include/TRKBase/AlmiraParam.h similarity index 94% rename from Detectors/Upgrades/ALICE3/TRK/base/include/TRKBase/AlmiraParam.h rename to Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/include/TRKBase/AlmiraParam.h index 9929a14c4e39c..53d4792f7c2a5 100644 --- a/Detectors/Upgrades/ALICE3/TRK/base/include/TRKBase/AlmiraParam.h +++ b/Detectors/Upgrades/ALICE3/TRKFT3/TRK/base/include/TRKBase/AlmiraParam.h @@ -25,7 +25,8 @@ namespace trk { struct AlmiraParam : public o2::conf::ConfigurableParamHelper { - static constexpr size_t kNLayers = constants::VD::petal::nLayers + constants::ML::nLayers + constants::OT::nLayers;
