摘要： 背景：在生成户外场景的真实感画面时，云彩扮演重要角色，云的真实感合成与显示也一直是计算机图形学的重要研究课题之一。为此，需要构建真实感云彩的模型，开发相应的绘制和动画仿真算法，对云的形状和外观进行控制来获得特定的视觉效果。
方法：本文采取逆设计方法进行云的视觉模拟：基于云的二维轮廓线生成其三维形状信息来控制云的形状；利用真实云彩的照片找到合成云的真实图像的最佳参数来优化云的颜色。
关键词： 云;  程序建模;  基于图像的建模;  流体模拟;  反馈控制;  遗传算法    
Abstract: Clouds play an important role when synthesizing realistic images of outdoor scenes. The realistic display of clouds is therefore one of the important research topics in computer graphics. In order to display realistic clouds, we need methods for modeling, rendering, and animating clouds realistically. It is also important to control the shapes and appearances of clouds to create certain visual effects. In this paper, we explain our efforts and research results to meet such requirements, together with related researches on the visual simulation of clouds.
Key words: Clouds    Procedural modeling    Image-based modeling    Fluid simulation    Feedback control    Genetic algorithms
