Abstract: With the rapid development of computer graphics and the animation industry, it becomes an important way to produce animation works by using computer to realize motion editing and retargeting and build the character motion library for reuse. This paper introduces a character motion trajectory extraction and retargeting method. This method can realize the reuse of the character motion by recording the motion trajectory of a character’s end joint, using certain normalization rules to extract the trajectory and build a character motion library, and retargeting to another character by a CCD IK solver. It proves that such method is ideal.

Key words: motion retargeting, motion trajectory, inverse kinematics
