| 摘 要： | 基于物理规律的计算机动画一直是图形学领域的研究热点，将一种新的动力学分析方法数值流形法引入到计算机动画领域中，利用数值流形法建立连续与非连续变形体的统一物理模型，仿真了一个逐渐展开的卷曲橡皮条、一个小球落到一堆可变形正方块上，以及一个球经过旋转的齿轮的情形。仿真结果显示，该模型可以处理多变形体的大位移和大变形，也可以处理变形体中裂隙的张开和滑移。

| Abstract: | Physics-based animation has always been an issue of computer graphics. A new numerical computing method named Numerical Manifold Method is firstly introduced into the area of computer animation. A general mechanical model is developed by making use of the advantage of numerical manifold method. It is simulated that an elastic object is being unfolded, a ball collapses into a square consisting of several little elastic blocks, and an elastic ball is pulled through rigid running gears. Simulation results show that the mechanical model has the potential advantage on multi-deformable objects simulation and the creation and spread of the joints. |
