OpenSubdiv/opensubdiv/far/subdivisionTablesFactory.h
Nathan Litke b7a763853c Added the CATMARK_RESTRICTED_VERT_VERTEX_A, CATMARK_RESTRICTED_VERT_VERTEX_B1, and CATMARK_RESTRICTED_VERT_VERTEX_B2 kernels which compute vertices resulting from the refinement of a smooth or (fully) sharp vertex.
* CATMARK_RESTRICTED_VERT_VERTEX_A handles k_Crease and k_Corner rules
* CATMARK_RESTRICTED_VERT_VERTEX_B1 handles regular k_Smooth and k_Dart rules
* CATMARK_RESTRICTED_VERT_VERTEX_B2 handles irregular k_Smooth and k_Dart rules
