摘　　要：本文对计算机图形学中三维云的建模和绘制技术进行了概述,主要介绍目前比较典型的基于个体生长的云建模技术和基于物理过程的云建模技术。对基于个体生长技术中比较成功的粒子系统模型、变形球模型、体元模型、过程纹理函数模型进行详细分析,并总结了它们的成果与不足,比较了它们的适用范围,为研究三维云可视化技术提供借鉴。The methods of cloud modeling and rendering in computer graphics are summed up. The succeeding and typical genetic technology and physically based technology at present are summarized. The main methods are analyzed based on particle system, meta-ball ,voxel vol- ume ,procedural textures. Have summarized their achievement and deficiency, has compared their scope of application. Offering reference for the visual technology of the three-dimensional cloud ,the development of artificial research of natural phenomena simulation is promoted.
