粒子系统是一套新颖特殊的构造、绘制景物的方法。首先介绍

了粒子系统描述物体的过程，以及对粒子属性和生命周期的表达、控制原理，同

时简单地比较了正反向纹理映射方法的优缺点。分析了结合粒子系统和纹理映射

对火焰模拟的过程，以及在对火焰模拟实践中，为求达到实时性和真实感效果要

注意控制的因素。最后给出了作者已经实现了的模拟效果图。-Particle system is a new special construction, drawing landscape approach. Particle system first introduced the process describe the objects, as well as particle properties and expression of the life cycle, control theory, while a simple comparison of the pros and cons to the texture mapping methods advantages and disadvantages. Analyzed the combination of particle systems, and texture mapping of the flame simulation process, as well as in the fire simulation in practice, in order to achieve real-time and realistic effects would not pay attention to controlling factors. Finally, the author has achieved the simulation results Fig.
