Research on Motion LOD Technique Based on Motion Capture Data

The motion capture technology by which can obtain perfect reality animation is applied in computer human animation widely,but the number of animation characters is limited because of large data came with motion capture technology. So the goal of simplify of characters in virtual environment is to reduce the cost of rending the characters but not affect the vision representation. Introduced LOD to character animation,classified the motion LOD,presented frame distance which compute with the rotation channels of joints to generate and control different motion LOD models,and analyzed the criterions of LOD model choosing for different motion behavior,our methods achieved good effect both in disperse LOD and progress LOD,motion LOD is the effective method for improving the rending speed and increasing the number of characters.
