A method of real-time human motion retargeting for 3D terrain adaption

It is difficult to genarate the adapting 3D terrain animation of a virtual role which is controled by motion capture. This paper presents a technique for real-time human motion retargeting on 3D terrain. First, the method based on geometry scaling was used to generate an intermediate skelton. Then a novel terrain adaption method was used to correct the positions of the intermediate skeleton´s root node and end effectors dynamically. According to the motion trajectory law of human´s center of mass, the terrain adaption method phased to calculate the terrain height increment. Finally, The contraints of target skelteton are determined by using the configuration of intermediate skelton, and an inverse kinematics slover is used to generate the final configuration of target skeleton. The results show that the retargeting motion is realistic, and this method can satisfy the real-time requireme- nts in virtual environment, even the condition of the 3D terrain height is modified interactively.
