Patent ID: 8587581

Claim:
A method for rendering primitives in parallel, the method comprising: receiving primitives in a first order, the primitives encoded as a list of vertex indices; distributing the primitives for parallel processing in object-space by one or more processing entities to produce multiple streams, each stream including object-space processed primitive descriptors that represent individual primitives; routing the multiple streams of object-space processed primitive descriptors based on screen-space positions to produce a first stream of processed primitive descriptors representing primitives that intersect a first portion of a screen and a second stream of processed primitive descriptors representing primitives that intersect a second portion of the screen; reordering the object-space processed primitive descriptors in the first stream to match the first order, producing a reordered first stream of object-space processed primitive descriptors; reordering the object-space processed primitive descriptors in the second stream to match the first order, producing a reordered second stream of object-space processed primitive descriptors; and rasterizing the primitives that intersect the first portion of the screen, and are represented by the first stream of object-space processed primitive descriptors, and the primitives that intersect the second portion of the screen, and are represented by the second stream of object-space processed primitive descriptors, in parallel to produce rasterized pixels of an image.
