OGRE is a popular opensource 3D graphic rendering engine. To improve the efficiency of implementing character animation, standard BVH files should be exploited to reduce the workload of intermediate transformation. The structure functions of the BVH files is used to parse the animation data and the parsed data, which is loaded directly to the memory, and then realtime rendering is implemented in OGRE engine. The experiment results demonstrate that parsed BVH files can successfully drive the model, obtaining vivid and brilliant 3D rendering effect.
