1. A method for creating posed computer-generated models, the method comprising: receiving, at one or more computer systems, information specifying a first set of one or more poses associated with a model; receiving, at the one or more computer systems, information specifying a second set of one or more poses associated with the model; generating, with one or more processors associated with the one or more computer systems, a plurality of weights configured to control a rotation deformer, a squash and stretch deformer, or a specialized deformer based on the first set of poses associated with the model; storing, in a storage device associated with the one or more computer system, each weight in the plurality of weights in association with a corresponding pose in the first set of poses associated with the model; determining, with the one or more processors associated with the one or more computer systems, at least one weight in the stored plurality of weights configured to control a rotation deformer, a squash and stretch deformer, or a specialized deformer to approximate at least one pose in the second set of poses associated with the model; and generating, with the one or more processors associated with the one or more computer systems, information configured for posing the model based on the determined at least one weight; wherein generating, with the one or more processors associated with the one or more computer systems, the plurality of weights comprises averaging a first weight configured to control a rotation deformer or a similarly specialized deformer determined from a selected training pose in the first set of poses associated with the model based on at least a first angle associated with the training pose and a second weight configured to control a rotation deformer or a similarly specialized deformer determined from the training pose based on at least at least a second angle associated with the training pose.
