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.
- Added automated migration scripts for handle syntax, standard types, and macros
- Deprecated legacy `Standard_*` types and macros in favor of native C++ equivalents
- Introduced modern `occ` namespace with template-based type checking helpers
- Enhanced NCollection macros to support variadic arguments for complex template types- Added automated migration scripts for handle syntax, standard types, and macros

Majority of functions now simply call same functions from std namespace.
Functions that duplicate std namespace functionality are declared
deprecated.
Calls of deprecated functions are replaced with std functions calls.
Reorganizing structure to have Module/TK/Package/FILES structure.
New structure reflect the structure inside IDE.
Migrate FILES, PACKAGES, EXTRLIB to CMake version to handle changes on updates.
No changes were done to installation layout, all installation result keep as before.
The migration was done using python script, see PR, which refactor automatically the structure.
Updated doc generation to have valid path to modules, toolkits and packages.
In case of PR into new version, IR-790 can be used as a target for the previous version.
