ABSTRACT:
Methods and apparatus are disclosed for automatically generating features of computer animated objects that are represented by a skeleton surrounded by an envelope. An animator may modify the shape of the envelope for a particular configuration of the object's skeleton ("pose"). These envelope modifications for these poses are stored. When an animator desires to create a new pose, the stored modifications for previous poses are blended together, based upon the difference between each pose and the new pose, to automatically generate a modified envelope shape for the new pose. When satisfied with a particular envelope shape for a pose, the animator may store the modification in the database and the modification may then be used for subsequent poses.
