There seems to be some work at Brown University in distributing >ray-tracing over workstations. The Apollo animation, "A long ray's journey into light", which appeared at SIGGRAPH '85, was made by distributed ray-tracing. Each frame was farmed out to an idle workstation on the net. I believe upwards of 100 machines were used to complete the work. The more humorous statistic was the number of hours in total this took; I seem to recall something like 8 or 10 thousand. The video includes these stats at the end of the film, which was only about 3 minutes in duration! In article <12190@hubcap.clemson.edu> feldy@cs.ucla.edu writes: >R.E. Felderman, E.M. Schooler, L.

I'm sure you had a good reason for this subject's being pub- >lished in JSAC, but that reason is not immediately obvious to me. That particular JSAC happened to be a special issue on Personal Computer Communication. We had come at the problem of parallelism from a communications perspective. Having designed the BBL system to run on a network of idle PC's, the special issue struck us very appropriate.
