摘　　要：自然景物的模拟一直是计算机图形学中的热门研究课题,文章深入研究和分析了沙尘暴发生时沙尘的形态及运动状态,以Microsoft Vc++6.0编译环境为开发平台,基于OpenGL图形库,采用粒子系统模拟沙尘颗粒的运动,采用雾函数模拟朦胧的环境,完成了沙尘暴场景的模拟,其模拟效果逼真。Simulations of natural scenes have always been a hot research topic in computer graphics. This topic is studied and analyzed the shape and motion state of dust when the sandstorm occurs. It is adopted particle system to simulate the motion of sand particle and fog function to simulate dim environment, thus fulfilled the completion of dust storm simulation. The sandstorm simulation system is based on VC ＋ ＋ 6.0 build environment, OpenGL graphics library and has a realistic effect.
