| 摘 要： | 提出一种基于插值细分造型的织物模拟算法.通过对织物物理和几何属性分析,构造出一个带约束的几何模型,在改进的四点插值细分造型基础上,通过动态细分网格并结合曲面优化调整以达到高效模拟柔性织物自然行为的目的.克服了以往仿真方法中求解物理模型复杂、模拟过程难以控制的缺陷,简化了计算模型,提高了计算效率.最后,以织物模拟为例说明该算法的实现.

| Abstract: | A general algorithm based on interpolate subdivision surface to simulate stationary flexible cloth is presented. It offers a geometrical model of constraints by combining physical characteristic with geometrical characteristic. And 4_point interpolation subdivision scheme is introduced into optimization process, so predigesting model and improving simulation speed. It is avoided to complex computing of foregoing cloth_modeling techniques and hard controlling to simulation process. In the end, a cloth modeling is given to illuminate in detail the algorithm. |
