摘　　要：提出了一种改进的立体云模拟方法。它建立在Gardner的椭球模型基础之上,对其在模型的使用和模型填充方面作了改进和扩展。根据此模型建立的立体云模拟系统能够模拟出单朵云、积云、云海等不同的立体云现象,并且能够实现立体云的穿越,弥补了Gardner方法的不足。同时,给出了一些云彩生成过程中有关动态控制的关键问题和难点的解决方法。An improved simulation method on 3D clouds was proposed. It was based on Gardner＇s ellipse model which was improved and extended in model use and its filling. The simulation system based on the method could simulate different phenomena such as single cloud, cumulus or cloud sea, and realize 3D clouds traversing. Thus, the deficiency in Gardner＇s method was made up. Meanwhile, some solution was given on the key problems and difficulty met in dynamic control of the cloud generation.
