Abstract
The determination of the final posed position is optimized by tracking the changes in animation variables associated with the sequence of deformers over two or more poses. The earliest deformer of the sequence affected by a changed animation variable is designated the cached deformer, and the input to this deformer is stored for future use. For a subsequent pose, the animation variables changed from the previous pose are identified, and the earliest deformer of the sequence affected by these changed animation variables is compared with the cached deformer. If the earliest deformer affected is the cached deformer or is to be processed after the cached deformer, the final posed position of the control point can be determined from the stored intermediate value of the control point, rather than from the initial position of the control point.
