Import motion capture data which have the matching skeleton with character is often used in preset scene in character animation synthesis now. However

this method could not afford the demand of multiple topological skeleton structures and the changing scene in real time. In view of the above questions

this paper proposes a new algorithm of retargeting motion capture data to skeleton model with multiple arbitrary topologies and adopts intelligent character model based on the real time three dimensional path-planning algorithm

integrating with the method of using voice user interface instead of graphical user interface to implement verity movement of virtue character in a dynamical three dimensional scene. The result demonstrates that slick and interactive animations can be synthesized by the proposed method. The method downs the cost of animation synthesis by improving the reuse rate of motion data and can be used widely in human-computer interaction domain by satisfying the need of synthesis of character animation in varied three dimensional virtual scenes.
