1) Extend Poly_Triangulation by mesh purpose, possibility to be cleared and late-load deferred data interfaces.
2) Update BRep_TFace to store list of triangulations istead of single one. And also active one. Update getter and setter of single triangulation and add new methods to interaction with whole triangulations list.
3) Update BRep_Tool to get single triangulation of face according to the input mesh purpose or whole triangulations list.
4) Update BRep_Builder to make face by not only single triangulation but whole triangulations list with specified active one.
5) Add new methods to BRepTools to interact with shape triangulations (Load/Unload/Activate/LoadAll/UnloadAllTriangulation(s))
6) Add new 'tlateload'command for shape to load/unload/activate triangulations.
7) Update 'trinfo' command by '-lods' options to print detailaed information about LODs of this shape
8) Support empty triangulations by selection. Use bounding box selection in this case.
9) Add new 'outdisplist' option to XDispaly command to print list of displayed objects to output variable but not to theDI
10) Add new '-noecho' option to vdisplay command to skip printing of displayed objects to theDI
11) Create new RWMesh_TriangulationSource as mesh data wrapper for delayed triangulation loading.
12) Create new RWMesh_TriangulationReader as base interface for reading primitive array from the buffer.
13) Cache nodes/triangles number defined in glTF file
14) Use RWMesh_TriangulationSource class as base of RWGltf_GltfLatePrimitiveArray one and RWMesh_TriangulationReader class as base of RWGltf_TriangulationReader one
15) Add possibilty to support of LODs by glTF reader. It is possible to skip data loading and load them later
16) Add new '-skiplateloading' (to skip triangulation loading), '-keeplate' (to keep information about deferred storage to load/unload triangulation later),
'-toprintdebuginfo' (to print additional debug information) options to ReadGltf command
17) Add new test of glTF late loading
Introduced NCollection_AliasedArray collection defining a general byte array
to be aliased as array of elements of mutable type.
Poly_ArrayOfNodes specializes this interface for collecting 2d/3d points with single/double precision.
Poly_Triangulation relies on this new class for definition of 3D nodes and UV coordinates
using gp_Pnt and gp_Pnt2d by default as before.
RWGltf_CafReader now fills in triangulation using single precision by default (as stored in the file).
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
Information about normals are stored in BinOCAF, XmlOCAF, BRep and BBRep (in case of triangulation-only Faces).
Versions of formats have been changed (11 for TDocStd, 4 for BRep Shape and 3 for Binary BRep Shape)
theWithNormals parameter added to BRepTools::Write()
IsWithNormals()/SetWithNormals() function added to BRepTools_ShapeSet
-normals/-noNormals option added to StoreTriangulation DRAW command
-normals/-noNormals option added to writebrep DRAW command
Tests for writing to brep/binary brep/BinXCaf/XmlXCaf added
Test for StoreTriangulation options -normals/-noNormals added
- Provide DumpJson for geometrical, ocaf and visualization classes;
- Change depth parameter of DumpJson (constant is not obligate here)
- Introduce a new macro for transient objects to be called as the first row in DumpJson: OCCT_DUMP_TRANSIENT_CLASS_BEGIN. We need not put the class name in the macro, using get_type_name of Standard_Transient for it.
- change implementation of OCCT_DUMP_CLASS_BEGIN and OCCT_DUMP_TRANSIENT_CLASS_BEGIN. It is not an sentry more and it does not create a new hierarchy level. It appends a new row into the output stream: "className": <className>
- OCCT_DUMP_* does not require semicolon
- class header is included first in source files of TDataStd, TDocStd, TCAFDoc
NCollection_Array1 now provides method Resize() for re-allocating array to new bounds.
Added Move Constructor and Move Assignment operator.
Added empty constructor defining array of zero size.
Poly_Triangulation, dropped duplicating fields myNbNodes and myNbTriangles.
Removed unused file Poly_Triangulation.lxx.
Use std::move within NCollection_Array1::operator=() [fix for 0028470]
Macro NO_CXX_EXCEPTION was removed from code.
Method Raise() was replaced by explicit throw statement.
Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer.
Method Standard_Failure::Caught() is deprecated now.
Eliminated empty constructors.
Updated samples.
Eliminate empty method ChangeValue from NCollection_Map class.
Removed not operable methods from NCollection classes.
* The possibility to copy mesh is implemented. It may be enabled by copyMesh flag, by default it is disabled.
* Poly_Triangulation::Copy() method is added.
* The mesh is copied if and only if copyMesh flag is true.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":

- All packages are converted to nocdlpack
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
