碩士 === 國立臺灣大學 === 資訊管理學研究所 === 94 === To edit or create the animation of a 3D character model has always been an important but time-consuming task, since the animator usually needs to set up the character''s skeleton, paint its binding weights, and adjust its key-poses. Therefore, systems and algorithms have been proposed to improve the animating pipeline in both efficiency and quality concern. Hence, we propose an animation transfer system in this thesis to take a well-edited character animation as the input. Then, the system can transfer the skeleton, binding weights, and other attributes of the given character model to another static model with only few corresponding feature points specified. The transferring process is based on a mapping between the space around two character meshes. In this thesis, the mapping is called consistent volume parameterization, which inherits consistent surface parameterization. With this method, the skeleton, binding weights, and other attributes transferred by our system are nicely generated and ready to be edited. Hence, the animator can start to create a skeleton-driven animation for the new character model without any prior setting. Moreover, our system is also capable of cloning a skeleton-driven animation to several other character models which can be used in a crowd animation.
