一种基于GPU的火焰实时模拟算法
|
摘要
针对国内外目前学术界的3种主要火焰模拟方法所存在的问题,提出了一种基于GPU的火焰实时模拟算法,本方法有机地结合了粒子系统方法和基于数学物理的方法,能够同时满足计算机图形学一直以来孜孜以求的"实时性"与"真实性"两大目标.通过实验仿真得出结论:火焰模拟结果显示能够达到每秒60帧,符合实时模拟的要求,能够得到更加接近于真实状态的火焰动画,尤其是细节更为清晰.
Aiming at the problems existing in the current three main flame simulation methods in academia at home and abroad,a flame real-time simulation algorithm based on GPU was proposed. This method combined organically the particle system method and the mathematical physics method. Satisfying the two goals of "realtime"and "authenticity"that computer graphics have been pursuing for a long time,we have reached the conclusion through experiments,the flame simulation results could reach 60 frames per second,which meet the requirements of real-time simulation,and could get closer to the reality. The state of the flame animation,especially the details was more clear.
