Original Abstract Submitted
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.
