Abstract

In Computer Graphics, it is always a challenge research issue for the virtual actor (avatar) to have the ability of visual perception and response to the virtual world. However, expressions of his/her avatar play an important role in virtual environment when facing the events. In this paper, we present a new approach of interactive model between avatar expressions and virtual world. The virtual character is considered as an agent, firstly, avatar recognizes the 3D object in the environment and calculates the orientation of the 3D models, so that avatar percepts the surrounding; According to the IF-ACTION rule-base, avatar can express its expression. Expressions of individuals can be simulated by expression clone and face 3D model reconstruction based on facial muscular model. Experimental results show that the approaches we present can be realized, and the results also show the high prospect of our method.
