Abstract
A system and method for performing tessellation of three-dimensional surface patches performs some tessellation operations using programmable processing units and other tessellation operations using fixed function units with limited precision. (u,v) parameter coordinates for each vertex are computed using fixed function units to offload programmable processing engines. The (u,v) computation is a symmetric operation and is based on integer coordinates of the vertex, tessellation level of detail values, and a spacing mode.
