基于弹簧质点模型的三维布料仿真

3D Fabric Simulation Based on Spring Particle Model

随着游戏、动画、工业等商业领域的快速发展,较多研究者尝试使用计算机模拟真实世界物体形变,其中布料仿真是物体形变研究中的热点和重点。文章是基于欧拉显式积分和Verlet积分在布料模拟中的研究和实现。文章通过对比两种不同积分算法的研究,表明欧拉显式积分所获取的效果更具有真实性,但会出现超弹性现象,而Verlet积分所获取的效果具有稳定性,但存在失真性。当两种算法在布料模拟中的质点数较多时,文章采用通用图形处理器(General-Purpose computing on Graphics Processing Units,GPGPU)计算来弥补算法的不足。

With the rapid development of commercial fields such as games,animation and industry,many researchers use computers to simulate the deformation of objects in the real world.Fabric simulation is a heat topic and key points in the research of object deformation.This paper is based on Euler explicit integral and Verlet integral in fabric simulation research and implementation.By comparing the research results of two different integration algorithms,it is shown that the effect obtained by Euler's explicit integration is more authenticity,but there will be hyperelasticity phenomenon:the effect obtained by Verlet integration has stability and also has inauthenticity.When the number of particles of the two algorithms is large in fabric simulation.Therefore,the paper uses General-Purpose computing on Graphics Processing Units(GPGPU)to make up for the shortcomings of the above two algorithms.
