Oh, forgot to mention... All the articulated animation was done using the graphics card. Not raytraced. Its, what do you call it, OLE? That was done while the CPU was doing the raytraced scenes in the background. Again this was to get the thing done. The two different methods, of course, look very different on screen. Principal photography took 4 months. The voices took a long time to find. It was previewed at a film-school and the lack of comprehension was so great that 10 mins more was filmed and new voice-overs added to make it easier to follow.
