变形传递（ Deformation Transfer ）是将源网格的变形传递到目标网格上，使目标网格具有与源网格相似的变形。本文通过构造具有源网格的拓扑结构且与目标网格有相似的几何外形的中间网格，建立源网格与目标网格三角形之间的对应关系，对应的三角形具有相同的变形梯度，将源网格的变形传递到目标网格上。-Deformation transfer (Deformation Transfer) is the source of the grid will be passed to the target grid deformation, the target and the source mesh grid has a similar deformation. By topology mesh structure having a source and target grid and have similar geometry in the middle grid, establishing correspondence between the source and the target mesh triangle mesh between the corresponding triangle has the same deformation gradient, the source grid deformation is transmitted to the target grid.
