Detailed Description

Represents piece of ModelData_PolyVertexSet using set of indices.

Full ModelData_PolyVertexSet is a mesh representation for a body produced by ModelAlgo_BRepMesher. Usually it's a mesh for the entire body. If the body has multiple appearances (colors), then a mesher generates a poly vertex set for each region with a single appearance, therefore this poly vertex set is a mesh for one of these regions. If a single ModelData_PolyVertexSet is needed for a multicolored body (with consistent indexing for all subshapes) you can set SaveAppearances flag to false in ModelAlgo_BrepMesher.

This class represents a result of meshing a BRep shape and can be produced by ModelData_BRepToPolyAssociations class. It can represent the following types of geometry depending on the type of the input shape:

In case of ModelData_Face, it will represent a set of triangles from PolyVertexSet (which will have ModelData_IndexedTriangleSet type) IndexArray would contain triangle indices from this ModelData_IndexedTriangleSet.
In case of ModelData_Edge, it will represent a polyline. PVS can have a type of ModelData_IndexedTriangleSet or ModelData_PolyLineSet, IndexArray would contain vertex indices (in order) for this polyline.
In case of ModelData_Vertex, it will represent a point. IndexArray would coontain vertex indices in ModelData_PolyVertexSet.
