Abstract

See full text

In accordance with some embodiments, domain shader and/or tessellator operations can be eliminated when they are redundant. By using a corner cache, a check can determine whether a given corner, be it a vertex or a quadrilateral corner, has already been evaluated in the domain shader and/or tessellator and if so, the result of the previous operation can be reused instead of performing unnecessary invocations that may increase power consumption or reduce speed.
