虚拟战场中车尾扬尘的实时仿真方法

基于扬尘现象的物理模型和粒子系统的基本原理,给出了一种车尾扬尘特效的快速实时生成算法.首先建立适用的扬尘粒子系统模型,再通过OpenGL的纹理映射、融合功能等技术对模型进行渲染,特别是从实时性角度入手对传统粒子系统进行改进,最终成功地运用到基于WTK平台创建的某型装甲车辆视景仿真系统的复杂地形中,在实时性和逼真度方面均获得了较好的效果.

Real-time Simulation of Dust Behavior in Virtual Battlefield

In this paper,a method is proposed to realize real-time simulation of dust behavior,which is based on the physical model of the dust behavior and the principle of particle system.First,define an applicable dust behavior particle system,next draw the system by OpenGL functions such as texture mapping and blending,especially,improve the real-time performance of the traditional particle system.Finally,the result shows the vivid appearance, and also meets the real-time requirement of the system when the method is applied to the complex terrain in the armored car vision simulation system developed on the platform of WTK.
