Compositing Digital Images Thomas Porter, Tom Duff July 1984 Most computer graphics pictures have been computed all at once, so that the rendering program takes care of all computations relating to the overlap of objects. There are several applications, however, where elements must be rendered separately, relying on compositing techniques for the anti-aliased accumulation of the full image.

Distributed Ray Tracing Robert L. Cook, Thomas Porter, Loren Carpenter July 1984 Ray tracing is one of the most elegant techniques in computer graphics. Many phenomena that are difficult or impossible with other techniques are simple with ray tracing, including shadows, reflections, and refracted light. Ray directions, however, have been determined precisely, and this had limited the capabilities of ray tracing. By ... more Paper (PDF) Available in the Proceedings of SIGGRAPH 1984 |
