Detailed Description

Object used to compute and query ptex face indices.

Given a refiner, constructing a PtexIndices object builds the mapping from coarse faces to ptex ids. Once built, the object can be used to query the mapping.

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.

Parameters

refiner	refiner used to build this PtexIndices object.
face	coarse face index
quadrant	quadrant index if 'face' is not a quad (the local ptex sub-face index). Must be less than the number of face vertices.
adjFaces	ptex face indices of adjacent faces
adjEdges	ptex edge indices of adjacent faces

f

)

const
