Abstract
A system and method for generating images of three-dimensional objects. The system includes one or more tracing processors, and one or more shading processors. Each of the tracing processors may be configured to (a) perform a first set of computations on a corresponding group of primary rays emanating from a viewpoint resulting in a ray tree and a set of one or more light trees for each primary ray of the corresponding group, (b) transfer the ray trees and associated light trees to one of the shading processors, and (c) repeat (a) and (b). Each of the shading processors may be configured to (d) receive ray trees and associated light trees from one of the tracing processors, (e) perform a second set of computations on the received ray trees and associated light trees to determine pixel color values, and (f) repeat (d) and (e) a plurality of times.
