一种结合骨架驱动的Laplacian网格变形方法

A Method of Laplacian Mesh Deformation Combined with Skeleton Subspace

为了解决骨架方法在网格变形中容易丢失细节的问题,同时为了便于Laplacian网格变形中控制点的选取,本文结合网格简化和微分坐标技术,提出一种通过骨架驱动来保持细节特征的网格变形方法。首先建立原始输入网格的简化模型与骨架节点,通过操纵骨架点对简化模型进行变形,变形后产生的顶点作为原始网格的Laplacian变换中的控制点,最后利用这些自动生成的控制点对原始模型进行Laplacian变形。从实验结果看,效果良好。

To deal with the problem of losing details in mesh deformation with skeleton subspace,and relieve the workload of selecting control points in Laplacian mesh deformation,the paper presents an integrated method of mesh deformation by using mesh simplification and Laplacian coordinates. We first construct the simplified mesh and its skeleton points of original model,then deform the simplified mesh by manipulating the skeleton points,and assign all vertices as control points from the deformed simplified mesh,finally,deform the original mesh by Laplacian deformation with all these points. The examples show that this method usually gives better results.
