Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., GPU. The apparatus may obtain an indication of a set of primitives for a draw call operation. The apparatus may also identify a subset of primitives in the set of primitives, each of the subset of primitives including a primitive portion that is outside of a viewing frustum for the draw call operation, and the primitive portion corresponding to less than all of each of the subset of primitives. Further, the apparatus may calculate an area of each of the subset of primitives including the primitive portion that is outside of the viewing frustum. The apparatus may also perform, or refrain from performing, a clipping operation for each of the subset of primitives based on the area of each of the subset of primitives being less than or greater than an area threshold.

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.
