Technical Reports One important part of character animation is facial animation - often the only vehicle available in a scene for the expressing of emotion. A facial model must be able to supply the visual cues associated with such emotions as fear, happiness, surprise, etc. The level of expressiveness of the model is directly related to the resolution of the model and the ability to control the individual facial features. Any model produced must therefore have enough identifiable control points to produce a recognisable human face with adequate flexibility.
Standard high accuracy Stereo Photogrammetry techniques as well as rough right angle "orthographic" projection techniques were used to digitise a human face. The results of the two methods are compared in the light of the requirements above.
The facial model produced is used for research in character animation at Curtin University of Technology.
It is shown that a high quality facial model with the required level of expressiveness can be digitised at a relatively low cost in terms of resources and time.
