Abstract

Techniques are described that can delay or even prevent use of memory to store triangles associated with tiles as well as processing resources associated with vertex shading and binning triangles. The techniques can also provide better load balancing among a set of cores, and hence provide better performance. A bounding volume is generated to represent a geometry group. Culling takes place to determine whether a geometry group is to have triangles rendered. Vertex shading and association of triangles with tiles can be performed across multiple cores in parallel. Processing resources are allocated for rasterizing tiles that have been vertex shaded and binned triangles over tiles that have yet to be vertex shaded and binned triangles. Rasterization of triangles of different tiles can be performed by multiple cores in parallel.
