摘　　要：变形传递是将已有模型上的变形传递到目标模型上,使目标模型能呈现出与源模型相似的变形效果.该文在Sumner等人提出的基于三角网格上的变形传递的基础上,实现了将源网格多种不同的变形传递到同一目标网格上的混合变形传递.在这个过程中提出了两种方法,一是直接将源网格多个部分不同的动作混合传递到目标网格,另一种是先将源网格进行动作融合,再将混合动作传递给目标网格.本文采用在分块时使各部分在边界处具有重叠的三角形和在能量方程中增加边界处的光滑项两种方法,最后得到了光滑的混合变形传递结果.Deformation Transfer is a technique which applies the deformation exhibited by a source mesh onto a different target mesh and makes it act like the one before. Based on the method proposed by Sumner in 2004, we successfully transfer the deformation on different parts of different source meshes to a same target mesh. To achieve this goal, we put forward two different ways- one is to directly transfer different deformation from different parts to the target, and the other is to blend different source poses firstly, then to do the Deformation Transfer. In each process, we propose two methods to get the smooth deformation along the deformation boundary, one is to re-divide the target mesh and make different parts own some same triangles on the deformation boundary, and the other is to add the smooth energy for the triangles on the boundary.
