It is course 16, titled ``Parallel Processing and Advanced Architectures in Computer Graphics.'' Unfortuantely, they are not generally available in libraries, and once they run out of conference copies, thats it as far as I know. Talk to someone at ACM SIGGRAPH for order info and more details. I don't have an address handy. It covers lots of stuff, from scanline rendering to radiosity, and has several good tidbits on Parallel Architectures for ray tracing. It talks about the Meiko Computing Surface, the Connection Machine, and the AT&T Pixel Machine, as well as others. Mostly just brief blurbs, but the appropriate references are there as well. For the AT&T Pixel Machine, check out the proceedings of ACM SIGGRAPH 89, pages 69-79. B -- Brian Corrie (bcorrie@csr.uvic.ca) Under the most rigorously controlled conditions of pressure, temperature, volume, humidity and other variables, the organism will do as it damn well pleases. Sounds like some of the code I have written...... 8-)
