Abstract

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 to be rendered. The merge engine merges the part image from its associated rendering engine with the part image provided by a prior merge engine and provides the merged part image to a next merge engine. One or more merge engines are designated the output merge engines and these output merge engines output a merged part image that is (a portion of) the ultimate output of the image generator, the full rendered image. Each merge engine performs its merge process on the pixels it has from its rendering engine and from its prior neighbor merge engine, in a pipelined manner and without necessarily waiting for all of the pixels of the part image or the merged part image.
