Description
TessCoord-
Decorating a variable with the
TessCoordbuilt-in decoration will make that variable contain the three-dimensional (u,v,w) barycentric coordinate of the tessellated vertex within the patch. u, v, and w are in the range [0,1] and vary linearly across the primitive being subdivided. For the tessellation modes ofQuadsorIsoLines, the third component is always zero.
