Descriptor class for PxTriangleMesh.
Note that this class is derived from PxSimpleTriangleMesh which contains the members that describe the basic mesh. The mesh data is *copied* when an PxTriangleMesh object is created from this descriptor. After the call the user may discard the triangle data.
| PxTypedStridedData<PxMaterialTableIndex> PxTriangleMeshDesc::materialIndices |
Optional pointer to first material index, or NULL. There are PxSimpleTriangleMesh::numTriangles indices in total. Caller may add materialIndexStride bytes to the pointer to access the next triangle.
When a triangle mesh collides with another object, a material is required at the collision point. If materialIndices is NULL, then the material of the PxShape instance is used. Otherwise, if the point of contact is on a triangle with index i, then the material index is determined as: PxMaterialTableIndex index = *(PxMaterialTableIndex *)(((PxU8*)materialIndices) + materialIndexStride * i);
If the contact point falls on a vertex or an edge, a triangle adjacent to the vertex or edge is selected, and its index used to look up a material. The selection is arbitrary but consistent over time.
Default: NULL
