Abstract
The basic ray-tracing algorithm is adapted to make ray-tracing faster for the production of motion pictures. Two algorithms are presented. The image space temporal coherence algorithm takes advantage of the fact that motion picture images do not change very much from frame to frame. The reprojection algorithm uses information about the object space saved from the previous frame to accelerate the processing of the current frame. The reprojection algorithm is used when the viewpoint of the current frame is changed by a small amount from the viewpoint of the previous frame.
