基于GPU和粒子系统的三维火焰模拟

基于粒子系统的火焰模拟是可视化仿真中的一个重要环节。目前，一些火焰模拟方法中的不足之处在于粒子计算时间长、渲染效果不真实等。基于粒子系统提出了一种三维火焰模拟算法，并利用GPU加以实现。其基本思想是运用物理动力学原理分析现实生活中的火焰运动，构建出火焰粒子系统模型并实现火焰的三维效果。实验表明，用该方法模拟火焰效果比较真实、速度快，在PC上可以得到令人满意的效果。

Three-dimension Flame Simulation based on GPU and Particle System

Flame simulation on the particle system is the important part of visual environment.At present,some flame simulation methods are confronted with the shortcomings such as time consume and low reality in image.This paper,presents a simulation method of three-dimension flame based on particle system,and is realized by GPU.The basic idea of the method is that the flame movement in the true life was analyzed by physics dynamics,then flame particle system model was constructed and 3D effect of flame was implement...
