摘　　要：三维云的模拟技术对飞行仿真系统的研究有着重要的理论和现实意义。本文对云的建模、光照、渲染三个方面进行了分析,根据云的特点,采用基于粒子系统的建模方法,结合纹理映射、光照模型来实现逼真的云层模拟效果。为提高渲染速度,本文采用Impostor技术进行加速绘制。经过试验,在Visual Studio 2010开发平台下,该技术较为真实的模拟了三维云层并满足了实时性要求。The modeling and rendering technology about 3D clouds play an important part in Flight simulation system in theory and practice.This thesis studies the modeling ,the light modeling and rending.According to the features of cumulus clouds, this thesis uses a method based on particle system and combine texture mapping technique and the lighting model of cloud to represent realistic cloud.In order to increase the speed of this render,this thesis uses the Impostor technology to accelerate the speed.The resuh shows that the mothod is effective and can even meet the the requirement of real-time animation on generic PC.
