| 摘 要： | 传统的自由变形方法通过计算控制晶格来变形,不适用于精确变形的情况。针对此问题,提出一种基于多不动点约束的网格模型局部编辑算法,该算法通过多个不动点的合理配置设定多种复杂的约束条件,实现网格模型的局部编辑,进而精确的变形模型。实验表明算法计算代价低,可实现精确变形。

| Abstract: | 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. |
