Abstract: This thesis focuses on the development of an easy to use real-time 3D human facial expression and animation system driven entirely by Facial Action Coding System developed by psychologists Paul Ekman and Wallace Frieson in 1977 [1]. The Waters muscle based facial model [2] has been used and extended to allow the user to calibrate the facial deformations illustrated by examples images of each AU in [3]. This becomes the basis of the facial expression creation. Our facial model is then animated in a physics-based manner by use of muscle contractions that in turn cause deformations on the facial geometry; the simulation is efficient enough to be rendered real-time on current PC hardware. Keywords: Facial animation, Facial Expression, Computer Graphics, Facial Action Coding System (FACS), Action Units (AUs), Muscle models, Low- Bandwidth teleconferencing.
