Fascinating factoid: Numbers of hours required to produce one on-screen frame in two decade-apart animated Pixar flicks:
- 1995 (Toy Story): 2 hours
- 2005 (Cars): 15 hours
The kicker, of course, is that there has been at least a 300x improvement in computer performance in the intervening decade. Animators, however, care naught for that, and just keep adding complexity per frame and soaking up the CPU cycles.
