Abstract: Methods, devices, and systems for rendering primitives in a frame. During a visibility pass, state packets are processed to determine a register state, and the register state is stored in a memory device. During a rendering pass, the state packets are discarded and the register state is read from the memory device. In some implementations, a graphics pipeline is configured during the visibility pass based on the register state determined by processing the state packets, and the graphics pipeline is configured during the rendering pass based on the register state read from the memory device. In some implementations, replay control packets, draw packets, and the state packets, from a packet stream, are processed during the visibility pass; the draw packets are modified based on visibility information determined during the visibility pass; and the replay control packets and draw packets are processed, during the rendering pass.

Abstract: Techniques for performing rendering operations are disclosed herein. The techniques include in a coarse binning pass, generating a sorted set of draw calls, based on geometry processed through a world space pipeline and vertex indices obtained from an input assembler.

Abstract: A graphics pipeline includes a tessellator stage having a sub-patch distributor and a plurality of tessellators. The sub-patch distributor divides an input patch into a plurality of sub-primitive groups, with the primitive group limit governing the maximum permissible size for a given group of sub-primitives to be assigned to a tessellator. The sub-patch distributor recursively identifies a plurality of regions of the input patch, with the size and number of primitives of each region based on the specified primitive group limit. The sub-patch distributor assigns different regions to different sub-patch groups and distributes the sub-patch groups among the plurality of tessellators.
