Two-level binning using delayed attribute shading

Abstract

An Accelerated Processing Unit (APU)[114] is configured to perform one or more attribute shading operations in the fragment shader[358]. For this purpose, the APU includes a processor core[116] configured to assemble one or more primitives from the generated vertex shading data[315]. The processor core culls one or more primitives to produce a set of residual primitives and identifies the primitives of the set of residual primitives that are visible in the bin. The processor core then provides the fragment shader with data[335] that identifies the visible primitives in the bin. Based on the data that identifies the visible primitives in the bin, the fragment shader generates attribute shading data[345] for each visible primitive in the bin.
