Abstract
Improvements in the graphics processing pipeline that allow multiple pipelines to cooperate to render a single frame are disclosed. Two approaches are provided. In a first approach, world-space pipelines for the different graphics processing pipelines process all work for draw calls received from a central processing unit (CPU). In a second approach, the world-space pipelines divide up the work. Work that is divided is synchronized and redistributed at various points in the world-space pipeline. In either approach, the triangles output by the world-space pipelines are distributed to the screen-space pipelines based on the portions of the render surface overlapped by the triangles. Triangles are rendered by screen-space pipelines associated with the render surface portions overlapped by those triangles.
