Abstract

By far the most challenging aspect of a photoreal actor is the creation of a digital face that can stand up to close scrutiny. The human face is an extremely complex biomechanical system that is very difficult to model. Human skin has unique reflectance properties that are challenging to simulate accurately. Moreover the face can convey subtle emotions through minute motions. We do not know the control mechanism of these motions. All these issues combine to make the human face one of the most challenging object to model using computer graphics.
