Human Facial Anatomy and Expressions, and how they can be Realistically Represented using Computer Graphics
Facial animation is the most important part of character animation, and realistic and natural expression of emotions is one of the most important parts of animating a believable character. This, however, is also one of the most challenging aspects of animating a character. The human face is one of the most interesting and intricate parts of the human body. We can detect even the subtlest change of expression within the face, and its familiarity allows us to recognise one face out of a sea of hundreds that we come into contact with every day. In order to successfully animate facial expressions and emotion, a thorough understanding of the human facial muscular structure and how expressions are formed is necessary.
