摘　　要：三维云的模拟可以大大提高飞行模拟器视景的逼真度,粒子系统又是模拟三维云的有效方法。介绍了三维视景中模拟三维云的几种常用方法,分析了OpenGVS中仿真云的局限性以及粒子系统模拟三维云的优点,在分析粒子系统的基础上,提出了一种在OpenGVS中基于灰度图约束的模拟三维云的方法,利用该算法,通过恰当选择粒子数量和粒子模型可以在取得逼真效果的同时满足视景系统实时性的要求。最后给出了在OpenGVS中的实现方法。To simulate 3D cloud will improve the real degree of flight simulator visual scene greatly, and particle system is a powerful way to simulate 3D cloud. This paper introduces several 3D cloud simulation methods,analyses the localization of cloud simulation in OpenGVS and the strongpoint of the 3D cloud simulation base on particle system. It presents a method based on restriction of gray image to simulate 3 D cloud in OpenGVS. With proper particle model and particle quantity, the algorithm produce realistic effect and meet the need of the realtime processing of visual scene. Finally
