Abstract:
1. A method for presenting three-dimensional computer graphics images using multiple graphics processing units, comprising the steps of: (1) allocating three-dimensional computer graphics data to rectangular subvolumes that define a scene such that said allocated three-dimensional computer graphics data corresponds to a portion of the scene that lies within the rectangular subvolumes to which the multiple graphics processing units have been assigned; (2) rendering, by the multiple graphics processing units, said allocated three-dimensional computer graphics data; (3) combining said rendered three-dimensional computer graphics data, thereby producing a three-dimensional computer graphics image; and (4) selecting one of presenting a first set of said combined three-dimensional computer graphics data and combining, at a second stage image combiner, the first set of said combined three-dimensional computer graphics data received directly from a first first stage image combiner with a second set of said combined three-dimensional computer graphics data received directly from a second first stage image combiner.
