英文摘要：

The technique of automatic simplification is introduced into the traditional method of space time optimization and physical constraints are firstly combined with the traditional method of path transformation. So the physical reality of the resultant motion is ensured and the convergence of the optimization process is speeded up. The algorithm contains 5 stages： model simplification, motion simplification, path editing, motion synthesis and motion recovery. Experiments shows that by using the algorithm human motion can be mapped successfully from the old path to the new path.
