1) Add empty constructor for Poly_Triangulation(),
2) Add Poly_Triangulation::HasGeometry() method to check that triangulation has any geometry.
3) Add possibility to cache bounding box in Poly_Triangulation and use it later in case of empty triangulation.
4) Add Poly_Triangulation::MinMax() to extends input box with bounding box of triangulation.
5) Add Poly_Triangulation::UpdateCachedMinMax() to cache min - max range of this triangulation with bounding box of nodal data.
6) Add virtual Poly_Triangulation::computeBoundingBox() to calculate bounding box of nodal data.
7) Update BRepBndLib::Add/AddOptimal/AddOBB algorithms to check empty triangulation and use cached box in this case.
8) Update BRepGProp::roughBary/surfaceProperties/volumeProperties to skip empty triangulation.
9) Remove additional myBox from RWGltf_GltfLatePrimitiveArray and some hack to save this box as nodes of base Poly_Triangulation.
10) Cache min-max range from JT file during its parsing
Fixed license statements within files BRepGProp_MeshProps.cxx, BRepGProp_MeshProps.hxx,
OSD_ThreadPool.cxx and OSD_ThreadPool.hxx.
Removed non-ASCII char from BRepMesh_ModelHealer.hxx.
New algorithms calculating global properties on mesh data have been added:
- BRepGProp_MeshCinert computes the global properties of polylines represented by a set of points;
- BRepGProp_MeshProps computes the global properties of a surface mesh.
Existing tool BRepGProp now automatically uses new algorithm for triangulation-only faces.
By default, algorithm will use exact geometry objects (surfaces), when it is available (as before the patch);
this behavior can be switched by a new flag UseTriangulation, forcing usage of triangulation instead of exact geometry when both defined.
