Abstract: 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.

Abstract: The problem of generating high quality images with a rendering pipeline based on decoupled sampling may be addressed by generating non-extrapolated shading locations and by determining improved texture filtering footprints. This may be accomplished by performing shading at the center of a bounding box that bounds mapped shading samples.

Abstract: Depth of field may be rasterized by culling half-space regions on a lens from which a triangle to be rendered is not visible. Then, inside tests are only performed on the remaining unculled half-space regions. Separating planes between the triangle to be rendered and the tile being processed can be used to define the half-space regions.
