Character animation is an important research field of computer animation and virtual reality technology. In recent years, along with the animation production and the movie special effect industry vigorous development, as well as the modern medicine to the surgery simulation unceasingly thorough research. Animation for the physical reality of the increasingly demanding. Therefore, the design and production of character animation has received the attention of a large number of researchers and developed into a multidisciplinary and technical integrated field, it based on computer graphics and involves design of image processing technology, motion control principles, video technology, art, visual psychology, robotics, artificial intelligence, etc... The core of this paper is the composition method of character animation. It introduces the composition method of different character animation, how to produce the animation with high reality and accord with motion law. And make a comparison of the methods, find out the advantages and disadvantages, combined with the actual needs, the future in-depth research direction and issues.
