Last year I posted some excerpts to P3D from *IRIS Universe*, a professional
magazine from SGI which had a detailed description of the process in their
Spring '96 issue number 35. A remarkable team effort developed about 4
minutes of computer simulation using some remarkable tools. 

One of the final tools was a *HiPPI (Hi Performance Parallel Interface)
network of eight Silicon Graphics workstations boasting 84 CPU's.* The
rendered images, lots of them, were *scanned onto film on a Solitaire film
recorder. Each frame of the computer animations was computed at 4096 by 3002
pixel resoltuion to accommodate the IMAX motion picture frame, the largest
format in the world (about three times the area of normal 70 millimeter
film, or about 10 times the area of standard 35 millimeter film).* This was
done from about 60 Gigabytes of data.

The article used the title *Cosmic Voyage* but the animation results were
used in the movie *L5, First City in Space*.
