- Add helper to create shell with all faces reversed
- Test FaceRef stores REVERSED orientation for all faces
- Test ParentExplorer reports shell as parent for reversed faces
- Test Reconstruct produces valid face definitions
- Test shell reconstruction preserves REVERSED face orientations
- Unify test fixture names to BRepGraph_ReverseTest
- Kept TopoDS definition data local while storing root
and compound placements on graph references.
- Preserved located triangulation and polygon-on-triangulation
data during population.
- Preserved degenerate natural boundary edges and cleared
full-graph state consistently in Perform().
- Kept original TopoDS shape lookup bindings valid
across population and compaction.
- Rebuilt compacted compounds in two passes so nested
compound references keep their local placement.
- Added focused regression coverage for located meshes,
nested compounds, shape lookup, compaction, degenerate boundaries, and reset behavior.
- The Strtod() function used a shared static Bigint memory pool
(private_mem, pmem_next, TI0) without synchronization.
- When multiple threads called Strtod() concurrently (e.g. parallel
BRep reading), the pool was corrupted causing random mis-parses
of numeric values.
- Fix: declare private_mem, pmem_next and TI0 as thread_local so
each thread gets its own independent memory pool and freelist.
- Added Standard_Strtod_Test.cxx with parallel correctness tests
using OSD_Parallel::For.
- Added BRepTools_Test.cxx with integration tests for parallel
BRep file reading.
- Redesign seam detection/pairing to be connectivity-derived (`SeamPair()` walks sibling coedges on the same face with opposite orientations), with seam halves now present in wire `CoEdgeRefIds` to match TopoDS iteration.
- Move geometric continuity storage/round-trip to `BRepGraph_LayerRegularity` (including seam continuity), updating populate/reconstruct/editor APIs accordingly.
- Add/adjust GTests to cover seam ordering, seam symmetry, layer regularity behavior, and split/compact/reconstruct interactions under the new model.
- Replace various `Size()` calls with `Extent()`/`Length()` (int-returning) when passing element counts into `Message_ProgressScope`.
- Make “unsupported id type” fallbacks explicit in `BRepGraphInc_Storage` visitors to avoid MSVC control-path warnings.
- Minor warning-focused cleanups (loop variable rename in a test, use of `BRepGraph_NodeId::Invalid()`, removal of duplicated `Standard_EXPORT`).
- Replaced many direct field writes in tests with `EditorView` typed setters and `GenOps::RemoveRef`, and updated mutation-gen tests to use `MarkDirty()`.
- Added incremental reverse-index bind/unbind helpers in `BRepGraphInc_ReverseIndex` and updated editor operations to maintain the reverse index without full rebuilds in many cases.
- Extended `BRepGraph_Copy`/`BRepGraph_Transform` to `CopyNode`/`TransformNode`, adding optional mesh-copy/transform support and new coverage tests.
- Replace `BRepGraph_Builder::Perform()` with `BRepGraph_Builder::Add()` and introduce `BRepGraph::Clear()` as the rebuild boundary.
- Refactor product/occurrence editing APIs (e.g., `AddAssembly` → `CreateEmptyProduct`, `AddOccurrence` → `LinkProducts`, occurrence mutation via `Editor().Occurrences()`).
- Update a large set of GTests and inline docs to use the new lifecycle and API names.
- Removed multiple legacy DRAW test scripts and several QABugs DRAW command implementations.
- Added new GTest suites covering the migrated regressions in ModelingData/ModelingAlgorithms/FoundationClasses/DataExchange/ApplicationFramework.
- Updated multiple `FILES.cmake` lists to compile/link the new tests; introduced an additional `STEPControl_Writer::SetShapeFixParameters()` overload.
- Migrated node/ref/rep ID types and many count-returning APIs from `int` to `uint32_t`/`size_t` (history indices), updating iterators and bounds checks accordingly.
- Reworked numerous loops from raw integer indexing to typed-id iteration (`Start()`, `IsValid()`, range-for) across core code and tests.
- Expanded compaction test coverage (incl. bounding-box preservation assertion), plus clearer assertions/messages.
- Migrate NCollection map/sequence/array size APIs from int to size_t; Size() returns size_t, Length() remains the int accessor; int overloads delegate through NbBucketsFromInt() with a negative-input guard.
- Add NCollection_LinearVector: contiguous flat-buffer dynamic array with Standard::Reallocate-based growth for trivial types and move-construction for non-trivial types.
- Rewrite NCollection_DynamicArray on top of LinearVector<T*>; switch to power-of-two block sizing with precomputed shift/mask.
- Rework NCollection_BaseMap iterator with a forward findFirst() helper (no negative-bucket arithmetic); unify ReSize/BeginResize/EndResize on size_t.
- Enable thread-safe fast path in NCollection_IncAllocator via std::shared_mutex + CAS bump allocation on atomic AvailableSize; exclusive lock is taken only for new-block allocation and list reordering.
- Remove NCollection_BasePointerVector (superseded by NCollection_LinearVector).
- Remove NCollection_BaseMap::Statistics (unused).
- Add <cstddef> include in NCollection_Primes.hxx so size_t resolves on clean builds.
- Document iterator invalidation contract on NCollection_LinearVector.
- Unify BRepGraph programmatic mutation behind EditorView: delete BuilderView (2648+552 lines); EditorView (3186+930 lines) and EditorView_Mut.cxx own both structural creation (Add*/Remove*) and field-level RAII-scoped mutation (Mut*()) with automatic OwnGen and SubtreeGen propagation.
- Add BRepGraph_MeshCache and BRepGraph_MeshView: two-tier mesh storage separating algorithm-derived caches from persistent (definition) triangulations; freshness is keyed on FaceDef.OwnGen; cache writes do not mutate the model.
- Document the MeshCache invalidation contract in BRepGraph_MeshCache.hxx (which mutations bump Face.OwnGen and how markRepModified closes the loop for Surface/Triangulation reps).
- Add BRepGraph_RefsIterator (generic flat ref scan with RefTraits dispatch) and BRepGraph_ReverseIterator (typed parent-traversal wrappers over reverse-index vectors).
- Rework RefId entity model: replace inline refs with typed RefId vectors; add OccurrenceRef and Kind::Occurrence=7; BRepGraphInc_WireExplorer now requires a VertexRefLookup.
- Rename layers for consistency: BRepGraph_ParamLayer to BRepGraph_LayerParam, BRepGraph_RegularityLayer to BRepGraph_LayerRegularity; rename BRepGraphInc_Usage to BRepGraphInc_Instance.
- Replace RootNodeIds() with RootProductIds() returning product roots only.
- Update BRepGraph and BRepGraphInc READMEs; fix stale RootNodeIds reference.
- Sweep Size() to Length() renames across ~200 callers in TKG2d, TKG3d, TKMath, TKMesh, TKBO, TKOffset, TKShHealing, TKTopAlgo, TKBRep, TKService, TKV3d, TKOpenGl, TKMeshVS, TKDE*, TKXCAF, TKXSBase, TKLCAF, TKStd, and Draw harness.
- Add GTest coverage for new containers and the BRepGraph overhaul: NCollection_DynamicArray_Test, NCollection_LinearVector_Test, BRepGraph_Fuzz_Test, BRepGraph_Iterator_Test, BRepGraph_LayerIterator_Test, BRepGraph_MeshCache_Test, BRepGraph_MutGuard_Test, BRepGraph_ReplaceVertex_Test, BRepGraph_ReverseIterator_Test, BRepGraph_ScenarioMatrix_Test, BRepGraph_TypedIdDispatch_Test, BRepGraph_WireExplorer_Test.
Implement new representation of topology and BRep into OCCT.
New foundation represent 2 levels:
BRepGraph - public interfaces which making the topology graph representation
BRepGraphInc - internal structure which represent topology as an incident tables.
The foundation provides basic logic for conversion from TopoDS_Shape to BRepGraph and back.
The foundation provides the iteration and exploring interfaces to travel in both directions on any level of topology.
The internal id type of inc tables is 'int', which is not for long term and can be updated, better to use typed id aliases, even for the iterations, they provide all necessary operators.
The access to the BRepGraph is done using multiple View classes available by methods from main class.
The extensions on graphs is possible with 'Layer' and 'Cache', where first is persistent, second - temporary,
Some basic operations on graph also provided for compact, analyze and copy.
- Deleted GeomProp_Surface, GeomProp_SurfaceAnalysisTools, GeomProp_SurfaceOfExtrusion, GeomProp_SurfaceOfRevolution, and GeomProp_Torus classes along with their implementation files.
- Removed references to the GeomProp module from the CMake package configuration.
Normalize method separator lines across the codebase to exactly
100 characters (// followed by 98 = signs) matching the project
coding standard.
Translate remaining French comments to English in ModelingData
packages (TKBRep, TKG2d, TKG3d, TKGeomBase) and FoundationClasses.
Add [[nodiscard]] attribute to Copy() methods on Geom_Geometry,
Geom2d_Geometry, Geom_Transformation, and Geom2d_Transformation
to prevent accidental discard of returned handles.
Fix typo in AppDef_Variational::Dump() debug output: "Nombre of
3d par multipoint" -> "Number of 3d per multipoint".
Update .github/copilot-instructions.md separator examples to match
the corrected convention.
Replace two-step initialization (default constructor + Initialize) with
direct construction for 8 non-copyable/non-movable property and grid
evaluator classes. Objects are now always in a valid state after construction.
Refactored classes:
- GeomProp_Curve, GeomProp_Surface (TKG3d)
- Geom2dProp_Curve (TKG2d)
- BRepProp_Curve, BRepProp_Surface (TKBRep)
- GeomGridEval_Curve, GeomGridEval_Surface (TKG3d)
- Geom2dGridEval_Curve (TKG2d)
Changes per class:
- Remove default constructor and IsInitialized() method.
- Add constructors matching each former Initialize overload.
- Rename Initialize to protected initialization method for internal
and derived class use.
All callers updated across production code (Extrema, BndLib,
IntCurveSurface, IntPatch, HLRBRep, GeomGridEval derived classes)
and test files to use constructor-based initialization.
Add new BRepProp package to TKBRep as a thin wrapper over GeomProp:: free
functions for computing local differential properties of BRep edges and faces
without exceptions. Replaces the legacy BRepLProp macro-based (.gxx) pattern.
New package BRepProp (TKBRep) provides:
- BRepProp_Curve: Local curve property evaluator for BRep edges.
Delegates derivative computation to BRepAdaptor_Curve and passes results
to GeomProp::ComputeTangent, ComputeCurvature, ComputeNormal,
ComputeCentreOfCurvature. Three Initialize overloads: from TopoDS_Edge
(owning), from BRepAdaptor_Curve reference (non-owning), and from
occ::handle<BRepAdaptor_Curve> (shared ownership). Includes static
Continuity() methods for regularity analysis at curve junctions
(replaces BRepLProp::Continuity).
- BRepProp_Surface: Local surface property evaluator for BRep faces.
Delegates derivative computation to BRepAdaptor_Surface and passes results
to GeomProp::ComputeSurfaceNormal, ComputeSurfaceCurvatures,
ComputeMeanGaussian. Same three Initialize overloads as BRepProp_Curve.
Key design decisions:
- No variant dispatch needed: BRepAdaptor_Curve/Surface handle geometry-type
dispatch internally via virtual methods, so BRepProp is a thin wrapper
calling adaptor D1/D2/D3 then GeomProp:: free functions.
- Ownership pattern: occ::handle for owning case + raw const pointer for
non-owning case, consistent with GeomProp_Curve/Surface.
- Returns result structs with IsDefined flags instead of throwing exceptions.
18 GTests: 11 unit tests (line, circle, box, cylinder, sphere) and
7 cross-validation tests against BRepLProp_CLProps/BRepLProp_SLProps.
