Study of Modeling Technology of 3D Virtual Teacher in Virtual Learning Environment

At present, the lack of emotion is very serious in E-Learning. The most learning platforms can´t imitate teaching behavior of the real teacher, and can´t provide the emotional communication between teachers and students, so students are easy to lose learning interest. In 3D virtual learning environment based on virtual reality, a 3D virtual teacher can imitate the figure, action, facial expression and teaching behavior of the real teacher, which enrich emotional experience, arouse learning interest and promote creative thinking of students. The modeling technology of 3D virtual teacher is discussed in this paper.
