Those models which are used in movies or games generally belong to animatable models, which usually have skeletons in order to let artists to edit the models’ motion easily. Actually, generating animatable models and editing the motions cost a lot of time comparing with the whole production pipeline. Therefore we want to propose a new and good algorithm to generate 3D geometric model’s skeleton quickly and retarget the motion, skeleton, or binding weight to another similar 3D model. Many research groups also pay much attention to this topic.三維模型骨幹動態模型動作移轉skeletonanimatable modelmotion retargeting
