摘　　要：现有的火焰合成算法多数都是基于粒子系统,其主要缺点是运算量大。本文先用少量粒子勾勒火焰的外轮廓线,再用纹理绘制的方法填充火焰纹理。这样既利用了粒子系统形成轮廓线的真实感,又避免大量的粒子状态运算,并能体现动态火焰纹理的一致性和连续性。Most of existing methods for synthesizing fire image are based on particle system,a main drawback of which is heavy computation. This paper uses particle to draw outline of the fire and fill the fire body with texture taken from realistic fire video. Advantages of this method are that realistic outlines of fire body can be achieved while avoiding large computation involved in ordinary particle system,and dynamics and coherence are well presented in the fire series.

关 键 词：噪声函数 粒子系统 纹理绘制 动态纹理 一致性和连续性
