Abstract

In this paper we tackle the issue of 3D mesh deformation when hard constraints of warping are imposed by user or application. First, we propose a review of the most salient methods existent in the technical literature. Then we retain for a more detailed analysis only some variants of Laplacian coordinates and Radial Basis Functions techniques that allow fine local movements of vertices and respect a set of constraints. We evaluate the selected techniques in terms of quality deformation, computational efficiency and displacement accuracy. The best results are obtained for the CTPS C2a continuous radial basis function closely followed by CP C2 function.

具有硬约束的网格变形
在本文中,我们解决了当用户或应用程序施加硬约束时三维网格变形的问题。首先,我们对技术文献中存在的最突出的方法进行了回顾。然后,我们保留更详细的分析,只有一些变体的拉普拉斯坐标和径向基函数技术,允许精细的局部运动的顶点和尊重一组约束。我们在质量变形、计算效率和位移精度方面对所选技术进行了评估。以CTPS C2a连续径向基函数效果最好,其次为CP C2函数。
