My role on this show was more tool designer than production artist. Although I did produce a few shots, my biggest contribution was to develop the look and technique for the transition from "bad future world" to "good future world", playing off the bubble theme found elsewhere in the movie. I based the technique on some boolean CSG functions embedded in Renderman, but seldom used. I also worked in Houdini to construct an easy to use smokestack smoke generator. The rendering technique involved using about 100 metaballs, and their animation was based on path animation along a triplet of splines, which proved to be much more responsive and directable than gas simulations.
