    摘要: In some embodiments, a given frame or picture may have different shading rates. In one embodiment in some areas of the frame or picture the shading rate may be less than once per pixel and in other places it may be once per pixel. Examples where the shading rate may be reduced include areas where there is motion and camera defocus, areas of peripheral blur, and in general, any case where the visibility is reduced anyway. The shading rate may be changed in a region, such as a shading quad, by changing the size of the region.

    摘要: A graphics pipeline combines the benefits of decoupling sampling with deferred shading. In the rasterization phase, a shading point is computed for each sample. After rasterization is finished, the shading points are sorted to extract coherence and groups of shading points shaded. This enables high sampling rates with efficient reuse of shading, in addition to other unique benefits.

    摘要: 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 whose triangles have been vertex shaded and binned over tiles whose triangles have yet to be vertex shaded and binned. Rasterization of triangles of different tiles can be performed by multiple cores in parallel.
