Methods and apparatus for visibility stream management

Abstract:

The present disclosure relates to methods and apparatus for graphics processing. In some aspects, the apparatus can determine a plurality of sub-primitives corresponding to one or more primitives in an image. The apparatus can also determine visibility information for each of the sub-primitives. The visibility information can include information regarding whether the sub-primitive is visible. Further, the apparatus can identify one or more of the sub-primitives as visible based on the visibility information. The apparatus can also determine a sub-primitive visibility stream including the sub-primitives identified as visible. Additionally, the apparatus can render at least one of the sub-primitives identified as visible in the sub-primitive visibility stream. The apparatus can also identify at least one of the sub-primitives as not visible based on the determined visibility information. Moreover, the apparatus can determine to skip rendering the at least one of the sub-primitives identified as not visible.
