It gives the better result for the game and animation project. But this kind of system has some problems and there‘s still no enough solution to help the 3D users to take care of it. One of the main issues is the retarget system. The animators have to open the second 3D application to receive the Motion capture streaming data for activating their own characters. This cost memories and the users have to spend time for the second application training. And the other main problem is the proportion. If the computer model has different proportions from the animator, then their body segments will intersects to each other easily. For example, some cartoon characters have special figure, like long arms and a large head. The geometry of hands and head will intersect to each other many times. This could take animators into nightmare when they retarget the Motion Capture data to their cartoon characters. The thesis tries to solve the proportion problem from the special characters like cartoon. We try to combine the collision detection with LOD methods to solve the problem. We use the Low polygon model to detect the collision, and high polygon used to do other interacts like sliding or Stop follow. In this paper will see the calibration demonstration of our solution.
