In C++, delete/delete[] on nullptr and free(NULL) are guaranteed no-ops.
This removes redundant null-check guards before these calls across 39
files, reducing code noise without behavioral change. Also simplifies
map value cleanup in BRepClass3d_SolidExplorer by using iterator
reference instead of redundant hash lookups.
Introduce always-populated weight arrays in BSpline/Bezier curve and surface
classes using non-owning views over a static unit-weights buffer. Migrate
~100 callers across the codebase from deprecated copy-out APIs to direct
const-reference array access. Fix a long-standing typo bug in Hermit.cxx.
Infrastructure (BSplCLib, BSplSLib):
- Add BSplCLib::UnitWeights(n) returning a non-owning NCollection_Array1
view over a compile-time-initialized static array of 2049 ones; falls
back to heap allocation for larger sizes.
- Add BSplCLib::MaxUnitWeightsSize() (constexpr 2049) and
BSplCLib::UnitWeightsData() exposing the raw pointer for BSplSLib.
- Add BSplSLib::UnitWeights(nU, nV) returning a non-owning
NCollection_Array2 view when nU*nV <= 2049, heap-allocated otherwise.
Always-populated myWeights (Geom/Geom2d curve and surface classes):
- myWeights is now always sized to match poles count.
Non-rational: non-owning view via UnitWeights (zero allocation).
Rational: owning array with actual weight values.
- Add WeightsArray() returning const NCollection_Array1<double>& (curves)
or const NCollection_Array2<double>& (surfaces) that is always valid.
- Update all constructors, copy constructors, and restructuring operations
(IncreaseDegree, InsertKnots, RemoveKnot, Segment, SetPeriodic,
SetOrigin, SetNotPeriodic, ExchangeUV, etc.) to maintain the invariant.
- SetWeight: copies non-owning view to owned array before mutation when
transitioning to rational; assigns UnitWeights when becoming non-rational.
- Remove myRational derivation from myWeights.Size() in updateKnots();
rationality is now tracked explicitly via the myRational flag only.
- Fix Geom2d_BSplineCurve::InsertPoleAfter missing myRational update
after inserting a weighted pole.
- Fix Geom_BSplineCurve::DumpJson stale myWeights.Size() > 0 guard
(changed to myRational, matching all other classes).
Caller migration to direct array access (~100 files):
- Replace deprecated copy-out pattern (allocate temp + call Foo(temp))
with const-reference access for Poles(), Knots(), Multiplicities(),
UKnots(), VKnots(), UMultiplicities(), VMultiplicities(),
KnotSequence(), UKnotSequence(), VKnotSequence().
- Replace Weights() null-pointer patterns with WeightsArray() const-ref
or *Weights() dereference where null check is still appropriate.
- Affected modules: GeomConvert, Geom2dConvert, GeomLib, GeomFill,
ProjLib, ShapeUpgrade, ShapeCustom, ShapeConstruct, ShapeAnalysis,
ShapeAlgo, BRepLib, BRepGProp, HLRBRep, ChFi3d, ChFiKPart, BlendFunc,
FairCurve, IntTools, TopOpeBRepTool, TopOpeBRepBuild, LocOpe,
BRepOffset, Adaptor3d, GeomAdaptor, Geom2dAdaptor, BndLib, Extrema,
DrawTrSurf, GeometryTest, GeomliteTest, SWDRAW, QABugs,
GeomToIGES, IGESToBRep, GeomToStep, StdPrs.
Bug fix in Hermit.cxx (PolyTest, both 3D and 2D overloads):
- Fix typo: "Pole0 < 3" changed to "Pole0 < Pole3" — was comparing
a double variable against the integer literal 3 instead of the
variable Pole3 holding the endpoint weight value.
- Fix logic: "if (boucle == 1)" changed to "else if (boucle == 1)"
to make the boucle==1 and boucle==2 branches mutually exclusive.
- Add explanatory comments on BSplCLib::D1 calls that intentionally
pass weight values as scalar "poles" to evaluate the weight function.
NCollection_PackedMapAlgo migration (TDataStd, QABugs):
- Replace deprecated member functions (IsSubset, Subtraction, Subtract,
Unite, Intersect, IsEqual) with NCollection_PackedMapAlgo free functions.
GTests:
- New BSplCLib_Test.cxx: 5 tests for UnitWeights API.
- New BSplSLib_Test.cxx: 5 tests for surface UnitWeights API.
- New Hermit_Test.cxx: 11 tests for Hermit::Solution (3D/2D) and
Hermit::Solutionbis covering uniform, distinct, high-ratio, reversed,
symmetric weights and positive-poles invariant.
- Add WeightsArray tests to Geom_BSplineCurve_Test, Geom_BezierCurve_Test,
Geom_BSplineSurface_Test, Geom_BezierSurface_Test (2 tests each)
verifying const-ref return, non-owning for non-rational, owning for
rational.

Completed the migration of IntCurveSurface_ThePolyhedronOfHInter and
HLRBRep_ThePolyhedronOfInterCSurf to fully utilize shared template
functions in IntCurveSurface_PolyhedronUtils.pxx.
The original commit fff55ee5fc introduced the .pxx template pattern but
only migrated 4 functions, leaving significant code duplication between
the two polyhedron implementations
Changes:
- Extended IntCurveSurface_PolyhedronUtils.pxx with 15 additional
template functions: AllocateArrays, Destroy, NbTriangles, NbPoints,
Triangle, TriConnex, PlaneEquation, Contain, FillBounding, IsOnBound,
ComputeMaxDeflection, ComputeMaxBorderDeflection,
SetDeflectionOverEstimation, Parameters, Point (3 overloads)
- Refactored both .cxx files to delegate all logic to PolyUtils namespace
This aligns the Polyhedron classes with other properly migrated classes
(Polygon, Inter, QuadricCurveExactInter) where the Utils.pxx contains
all shared logic and .cxx files are minimal wrappers.
Modernized curve/surface intersection algorithms by replacing preprocessor-based
generic programming (.gxx macros) with C++ templates (.pxx headers):
IntCurveSurface package (TKGeomAlgo):
- Introduced IntCurveSurface_Inter.pxx with callback-based template functions
for intersection algorithms, replacing IntCurveSurface_Inter.gxx
- Created IntCurveSurface_InterUtils.pxx with utility template functions for
surface decomposition, UV clamping, and quadric intersection handling
- Added IntCurveSurface_PolygonUtils.pxx for polygon construction utilities
- Added IntCurveSurface_PolyhedronUtils.pxx for polyhedron construction utilities
- Added IntCurveSurface_QuadricCurveExactInterUtils.pxx for exact quadric
intersection computations
- Converted standalone implementation files from macro instantiation (_0.cxx)
to direct template usage (.cxx)
- Removed obsolete .gxx and .lxx files
HLRBRep package (TKHLR):
- Updated HLRBRep_InterCSurf to use new IntCurveSurface template utilities
- Converted HLRBRep polygon, polyhedron, and intersection classes to use
modern template instantiation pattern
- Removed legacy macro-based instantiation files (_0.cxx)
This refactoring improves code maintainability, enables better IDE support
and debugging, and aligns with modern C++ practices while preserving
the existing API and functionality.
- Replacing preprocessor-based generic programming with C++ templates
- Converting inline implementation files (`.lxx`) to inline definitions within header files
- Removing legacy instantiation files (`_0.cxx`)

deprecated.

- Replacement of hardcoded direction values throughout the codebase
- Added `noexcept` to transformation and mirroring methods across all 2D geometry classes
- Added `constexpr` to trivial getters, setters, and simple computational methods where applicable

- Convert several functions to constexpr where safe to allow compile-time evaluation.
- Initialize members via initializer lists for several GTrsf/GTrsf2d/Mat/etc constructors.
- Add noexcept to transformation/serialization helpers and small utilities where appropriate.
This enables better compile-time optimizations and safer noexcept semantics across TKMath gp primitives.
- Removal of self-referencing includes where files include themselves
- Elimination of duplicate include statements within the same file
- Cleanup of redundant includes in conditional compilation blocks

Used regex in src folder:
