| 采用粒子结构作为布的模型.该模型是将布的经线和纬线的多叉点当作一个粒子.在此基础上,将布的形变归纳为弹性形变、弯曲和剪切3类,并根据物理定律推导出这3种形变的能量函数.最后,对由布的能量函数构成的D'Alembert-Lagrange方程进行数值积分,得到布的动态真实感图形. |

| Abstract: |
| In this paper, cloth is modeled as a collection of particles that conceptually represents the crossing points of wrap and weft threads in a plain weave. Based on this model, the deformation of cloth is decomposed into stretch and repel, bend, and shear. And energy functions of the three kind of deformation are deduced by physical rules. Finally, dynamic realistic cloth graphs are obtained by integrating D'Alembert-Lagrange equation. |
