int GetNumFaces() const
Returns the number of ptex faces in the mesh.
Stores topology data for a specified set of refinement options.
PtexIndices(TopologyRefiner const &refiner)
Constructor.
Object used to compute and query ptex face indices.
Definition: ptexIndices.h:46
void GetAdjacency(TopologyRefiner const &refiner, int face, int quadrant, int adjFaces[4], int adjEdges[4]) const
Returns ptex face adjacency information for a given coarse face.
int GetFaceId(Index f) const
Returns the ptex face index given a coarse face 'f' or -1.
