If we can capture single person and use it to develop many other motion data, it would be much more efficient in production. In this thesis, we use Motion Capture System that captures a motion as original data, and then add Gaussian noise to the original motion data to make up thousands of new motion data. In a distant view, motions of these thousands of people look the same. For a near view, the skeleton’s size and natural behavior of the creatures will make their motion look different, therefore true and natural scene can be simulated. It he proposed system, we first define the joints of skeleton, and then use these data to capture motion data of actor. Based on motion data, we carefully generate new motion data. The skeleton size of virtual model and original model are different, so we need further positional constrains to fit the virtual model. Finally, we add muscles on the proposed virtual model
