Facial animation using muscles to control the mimic articulation of phonemes
This master thesis describes an approach to facial animation using the muscle feature of Autodesk Maya. The skeletal, muscular and skin anatomy of the human head is abstracted from nature. The muscular structure is modelled to act as a highly reusable interface between any skull and skin model. The muscle actions are based on the Facial Action Coding System and are implemented using weights painted on the skin mesh. By combining several muscle actions it is possible to animate facial expressions, e.g. emotions or phonemes. By animating the mimic articulation of several visemes, the accuracy, usability and performance of the developed approach is determined.
