1. A method for automatically animating lip synchronization and facial expression of three dimensional characters for films, videos, cartoons, and other animation products, comprising:

  • configuring a set of default correspondence rules between a plurality of timed input phonemes or other timed data and a plurality of morph weight sets; and

    specifying a plurality of morph weight set transition rules for specifying durational data for the generation of transitionary curves between said plurality of morph weight sets, allowing for the production of a stream of specified morph weight sets to be processed by a computer animation system for integration with other animation, whereby animated lip synchronization and facial expression of animated characters may be automatically produced.
