requires 1-based indexing (returns immediately when Index < 1).
This bug caused the first PCurve to be skipped, potentially leading to
incorrect edge gluing results in ShapeUpgrade_UnifySameDomain.
Changed: for (int aCurveIndex = 0;; ...) -> for (int aCurveIndex = 1;; ...)

Modernized and refactored the polynomial root-finding implementation
with improved numerical stability and modern C++ practices.
Key changes:

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.
Cleans up the BRepClass3d_SolidExplorer class by removing the
unused Bnd_Box member and associated code,
including preprocessor directives and function definitions.
The isVertexInsidePolygon method uses the winding number algorithm,
which computes cumulative angles from the test point to polygon vertices.
For a point inside a polygon, this sum should be ±2π.
The gp_Vec2d::Angle method uses an inverted sign convention where
CCW rotation gives negative angles. For CCW polygons, the total angle
is -2π, but the original check only accepted +2π.
Changed the condition from:
std::abs(Angle2PI - aTotalAng) > Precision::Angular()
to:
std::abs(std::abs(aTotalAng) - Angle2PI) > Precision::Angular()
This correctly handles both CCW (-2π) and CW (+2π) polygon orientations.
Replace custom HLRAlgo_PolyData::Box struct with standard Bnd_Box class
to leverage its built-in update functionality and reduce code duplication.
Changes:
- Remove HLRAlgo_PolyData::Box struct definition
- Update UpdateGlobalMinMax methods to use Bnd_Box::Update()
- Simplify bounding box computation logic using Bnd_Box methods
- Use C++17 structured bindings with Bnd_Box::Get()
- Added a default constructor to CSLib_Class2d for creating empty classifiers.
- Implemented move constructor and move assignment operator to optimize resource management.
- Updated IntTools_FClass2d and BRepTopAdaptor_FClass2d to utilize the new move semantics, eliminating unnecessary dynamic memory allocations.
- Replaced deprecated pointer-based storage with NCollection_Sequence for better memory management.
- Removed the obsolete BRepTopAdaptor_SeqOfPtr class to streamline the codebase.
BRep_Tool::CurveOnSurface expects Index >= 1, but the loop started
from ii = 0, resulting in a wasted iteration that always returned
a null pointer.
