		unsigned char	numElements
	)

inline

Constructor

Parameters

farDesc	Patch type descriptor
maxValence	Highest vertex valence in the primitive
subPatch	Index of the triangulated sub-patch for the given transition pattern. Transition patches need to be split into multiple sub-patches in order to be rendered with hardware tessellation.
numElements	The size of the vertex and varying data per-vertex (in floats)
