Generating Body Surface Deformation Using Level Set Method

摘要

Recently skeletal motion data is obtained from the motion capture and is used for movie and sports. The movie production does not need the skeletal motion data but the body surface data. It is difficult to generate body surface data from only skeletal motion data because muscle deforms according to the skeletal motion. Muscle deformation occurs with arm and leg joint rotation. In this paper, we visualize body surface deformation based on the deformation mechanism that is applicable to human motion according to anatomy based modeling. We propose the method generating body surface by covering the skeletal muscles using a thin film based on the level set method. We demonstrate the effectiveness of the system through the generation of the movement of a body builder by using the proposed system.
