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.
| PX_DEPRECATED PxReal PxTriangleMeshDesc::convexEdgeThreshold |
Range: (0, PX_MAX_F32)
Default: 0.001
| 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
