Al is a fat dude with clothes stretched taut. So they decided to model the creases and folds for certain poses, then use shape interpolation between the changes in position. All the animators had to do was animate the model and the clothes would follow. They have tons of geometry in this film. Two of the most geometrically complex scenes take place in a downtown area and in an airport.
Downtown is extra heavy.
Every block had 10 trees or more, every tree has thousands of leaves, every car has one or two people, and every person has thousands of hairs. None of it is fake, it's all geometry, once you move the camera, even a little, the trained eye knows something is wrong. To the see the picture of Al, visit Computer Graphics World To create toy story, the studio used 366 objects, in Toy story 2, there are approximately 1200 models that range in size from a pencil to an airport. They paid great attention to details that makes them almost exactly real. For example, the dust on Wheezy's , a toy penguin, shelf is created carefully.
