基于质点弹簧模型的实时布料模拟
|
摘要
随着计算机图形学和图形学硬件技术的发展,虚拟仿真中的布料模拟逐渐成为研究热点。随着虚拟仿真技术在电子游戏中的应用逐渐增多,用户对虚拟现实中布料模拟技术的要求也逐渐增加,在追求布料真实感的同时还强调实时性。在对布料进行模拟时,首先根据布料的物理特性构建弹簧质点模型,然后使用时间积分对模型质点弹簧进行计算。为了提高求解效率,采用预计算处理数据,求解隐式积分对模型进行求解,以模拟出布料真实感且达到实时效果。
With the development of computer graphics and graphics hardware technology,the cloth simulation in virtual simulation has become a research hotspot. With the increasing application of virtual simulation technology in the electronic game,the requirement of the cloth simulation technology in the virtual reality is gradually increasing,while the real-time is also emphasized. In the simulation of the cloth,the spring particle model is constructed according to the physical properties of the cloth,then the time integral is used to calculate the model particle spring,In order to improve the efficiency of solution,the implicit integral is used to solve the model in order to simulate the real sense of cloth and achieve real-time effect.
