Generating action data for the animation of characters

Action data for the animation of characters is generated in a computer animation system. Body part positions for a selected character are positioned in response to body part positions captured from performance data. The positions and orientations of body parts are identified for a generic actor in response to a performance in combination with a bio-mechanical model. As a separate stage of processing, positions and orientations of body parts for a character are identified in response to the position and orientation of body parts for the generic actor in combination with a bio-mechanical model. Registration data for the performance associates body parts of the performance and body parts of the generic actor. Similar registration data for the character associates body parts in the generic actor with body parts of the character. In this way, using the generic actor model, it is possible to combine any performance data that has been registered to the generic actor with any character definitions that have been associated to a similar generic actor.
