System and method for performing non-affine deformations

摘要

A method for performing non-affine deformations. The method includes receiving data representing mathematical vectors associated with elements defining an object. The elements are organized in a hierarchy, a different subset of mathematical vectors is associated with one or more elements, and the mathematical vectors within each subset are defined relative to a local coordinate space associated with each element. The method further includes determining that a first non-affine deformer is to be applied to a first set of the elements, and, for each element in the first set, applying the first non-affine deformer to world coordinate space values corresponding to the mathematical vectors within the subset of mathematical vectors associated with the element to generate modified world coordinate space values for the mathematical vectors.
