Abstract
A system and method for generating a three-dimensional image is provided. An embodiment of the present invention includes calculating the ambient occlusion at a vertex in multiple, independent stages. Determining the global AO at the vertex may be performed using a first technique. Determining the local AO at the vertex may be performed using a second technique. The total AO can be found as a function of the local AO and global AO.
