Abstract:Ruqian Lu, academician of Chinese Academy of science, put forward project "full life cycle automation of computer animation generation" in the 1990s. This technology inputs proper story with limited natural language to the computer, and from the beginning to animation generation, every step was completed in the computer assisted. In the animation, how to plan the character path has become the important factor that affects the animation effect. In this paper, a path planning method based on the animation scene planning information in PADL was proposed, in which A* algorithm is used with restricted conditions to create PCAL, finally animation was made by Motion Graph. Experiments showed that the method could automatically generate the path animation that met the specified requirements.
