review text: The basic ray-tracing algorithm is adapted to take advantage of temporal coherence and to make ray-tracing faster for the production of motion pictures. Temporal coherence can be either image space temporal coherence or object space temporal coherence. Three rendering techniques are described: the first technique is called the image space temporal coherence algorithm, the second technique is called the reprojection algorithm and the third technique is manual touch-up. The algorithms can be combined into a single program. The author presents timing results of an implementation of the reprojection algorithm.
