摘　　要：为了重用已有动画资源,提出一种基于均值坐标的三维动画传输方法.首先使用标记点在源网格和相应的目标网格间建立映射,然后采用均值坐标,根据源网格的动画来变形相应的目标网格.该方法不需要源网格和目标网格有相同的顶点数和三角面片数,也不需要有类似的拓扑信息.To promote the efficient reuse of existing animation resources, an approach for transferring 3D animation from a source mesh to a target mesh based on mean value coordinates is proposed. It first builds a constrained mapping between the source and the target meshes with a small set of markers, then deforms the target mesh adhering to the deformations of the source mesh by means of mean value coordinates. We make significant improvements over previous approaches, in particular, our approach no longer requires the source and target meshes to have the same topology and can transfer the deformation both efficiently and faithfully.
