Modeling 3D avatar is very useful in e-learning software, a believable 3D avatar can have complex facial expression, and how to construct complex facial expression is a very interesting topic. The concept of emotion vector is presented. Emotion state of a 3D avatar can be transformed to an emotion vector that is calculated by basic emotion vector. The concept of expression vector is established, expression can be transformed to expression vector that is calculated by basic expression vector. Emotion mapping is set up from emotion vector space to expression vector space. A preliminary experiment is carried on microcomputer.
