火焰模拟是粒子系统最主要的应用之一。火焰最主要的两个特性是其颜色变化和摇曳的动态效果。本程序基于粒子系统模拟火焰，对于火焰粒子系统中粒子产生、运动、消亡以及火焰渲染的过程进行了实现，并对火焰的强度、宽度、亮度、颜色进行控制和改变。

-Flame particle system simulation is one of the main applications. The two most important characteristics of the flame is its color changes and swaying dynamic effects. The program is based particle system simulation flame, flame particle system for particle generation, motion, and flame extinction rendering process was implemented and flame intensity, width, brightness, color control and change.
