Abstract

This disclosure describes a device configured to generate a primitive visibility stream that indicates whether respective primitives of a set of primitives are visible when rendered and to generate, based on the primitive visibility stream, a draw call visibility stream that indicates whether respective draw calls for rendering the set of primitives include instructions for rendering visible primitives of the set of primitives. Based on the draw call visibility stream indicating that a respective draw call does not include instructions for rendering visible primitives, the device is further configured to drop the respective draw call. Based on the draw call visibility stream indicating that the respective draw call includes instructions for rendering visible primitives, the device is further configured to execute the respective draw call.
