Alan Heirich, Laurent Moll, Mark Shand, Albert Tam, Robert W Horst: Parallel pipelined merge engines. Hewlett Packard Development Company, June 22, 2004: US06753878 (99 worldwide citation)

An image generator is organized into a plurality of rendering engines, each of which renders an image of a part scene and provides the part image to a merge engine associated with that rendering engine. The image is a part image in that it usually contains less than all of the objects in the image t ...
