一个基于粒子系统的战场火焰模型及其实现

A Model of Battlefield Flame Based on Particle System in Virtual Environment

作为虚拟战场中特殊效应的一部分，火焰和爆炸效果在整个系统中有着重要的作用。生成具有真实感火焰生成的重要步骤是建立相关的模型。本文介绍了一个基于粒子系统的战场火焰模型，该模型引入了随机过程，能够大大减少计算机的工作量，从而增加实时性，并能获得不同精细程度的火焰。最后给出了算法的实现结果。

As an important part of the so-called special effects in the virtual battlefield, the flame and explosive effects play a key role in the overall system performance. The crucial step toward realistic dynamic flame is to establish its proper model. This paper introduces a model of battlefield flame based on the particle system and presents its realization algorithm and corresponding result of real-time rendering.
