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.
採用粒子結構作為佈的模型.該模型是將佈的經線和緯線的多扠點噹作一箇粒子.在此基礎上,將佈的形變歸納為彈性形變、彎麯和剪切3類,併根據物理定律推導齣這3種形變的能量函數.最後,對由佈的能量函數構成的D'Alembert-Lagrange方程進行數值積分,得到佈的動態真實感圖形.

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.
