摘　　要：以第29届北京奥运会开幕式文艺演出中纸张变形仿真为需求背景,提出一种基于过程控制的纸张变形建模方法。在一定近似逼近以及先验知识指导下,该方法根据某一时刻各顶点的空间位置间接确定纸张各边的空间姿态;根据各边的空间姿态确定纸张的最终形态;通过控制点的运动过程控制纸张变形的过程,最终实现了纸张变形过程的可控性。该方法具有可控性高、实时性好、真实感强、实现简单等优点。To meet the requirements of the simulation of the 29th Beijing Olympic Games,a modeling method for paper deformation was proposed.It is based on procedure control.With the use of some pre-acquired knowledge and approximations,it＇s feasible to get the paper＇s four edges by the positions of its vertex.Furthermore,the posture of the paper can also be singled out by its four edges.Then it＇s comfortable to control the process of the deformation by controlling the movements of four vertices.It is amazing to use this method to simulate the paper＇s deformation,by which high speed,easy control,and good result can be obtained.
