织物动感模拟的研究与实现

Research and Application in Dynamic Cloth Animation

织物的动感模拟是虚拟现实、计算机动画以及3D游戏等领域中的一个热点问题。为了实现织物动感模拟的实时性和真实感,选用质点-弹簧模型进行物理建模。然而,质点-弹簧模型在应用中存在过度拉伸的问题,针对这个现象进行了处理,提出采用平滑过度的方法来解决此类问题。同时,提出了一种风力模拟算法,简化了运算,增强了织物在风中运动的显示效果。实验证明,这些方法使织物动感模拟达到了较强的实时性和真实感。

Cloth dynamic simulation is an active area in the fields of virtual reality,computer animation and 3D game. To achieve real-time and vivid effect in dynamic cloth animation,this paper adopts mass-spring model,but it has the ＂super elastic＂ effect.This paper gives a method to avoid this effect,and proposes a smooth adjustment method to settle this problem.In the same time,this paper proposes a wind power simulation algorithm to improve the computing efficiency and display effect in dynamic cloth animation.Experiment results demonstrate that those approaches arrive at real-time and vivid effect.
