Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for backface culling for guard band clipping primitives. A graphics processor may identify at least one backface primitive in a set of primitives that extends beyond at least one guard band, where the at least one backface primitive is identified based on a set of fixed point coordinates. The graphics processor may cull the at least one backface primitive. The graphics processor may transmit an indication of the culled at least one backface primitive.
