Making of video


1) Steve Buscemi had voice acting in two innovative CGI movies in 2001 (other is Final Fantasy: The Spirits Within).

2) Pixar created a new fur simulation program called Fizt (short for "physics tool"). After a shot with Sulley had been animated, the Simulation department took the data for the shot and added his fur. Fizt allowed the fur to react in a natural way. When Sulley moved, the fur would automatically react to his movements, taking into account the effects of wind and gravity as well. Almost 3 million hairs for Sulley was done.

3) The Fizt program also controlled movement on Boo's clothing, which provided another breakthrough. The deceptively simple-sounding task of animating cloth was also a challenge to animate because of the hundreds of creases and wrinkles that automatically occurred in the clothing when the wearer moved. It also meant solving the complex problem of how to keep cloth untangled – that is, how to keep it from passing through itself when parts of it intersect. Fizt applied the same system to Boo's clothes as to Sulley's fur. Boo would first be animated shirtless; the Simulation department then used Fizt to apply the shirt over Boo's body, and when she moved, her clothes would react to her movements in a natural manner.

4) The render farm for Monsters, Inc. was made up of 3500 Sun Microsystems processors, compared with 1400 for Toy Story 2 and only 200 for Toy Story.
