Local deformation of mesh model based on restriction of multiple fixed points
基于多不动点约束的网格模型局部编辑

The traditional free-form deformation methods by using control lattices are not suit for precise control of deformation. In order to solve this problem, a local deformation of mesh model based on restriction of multiple fixed points method was proposed, in which many complex restriction conditions were managed by using appropriate settings of fixed points and exact partial deformation model was obtained. Experimental results show that this algorithm can achieve exact deformation with low calculation cost.
