Clouds play an important role in enhancing the realism of outdoor scenes in computer graphics (CG). Realistic cloud generation is a challenging task, which entails processes such as modeling, photorealistic rendering and simulation of the clouds. To these ends, several techniques have been proposed within the CG community in the last 4 decades with one or more of the above stated focuses. The growth of modern hardware has also enabled development of techniques that can achieve cloud display and animation at interactive frame rates. In this survey, we review the prominent work in the domain and also summarize the evolution of the research over the time.

计算机图形学中云的建模、渲染和动画研究

云在增强计算机图形 (CG) 中户外场景的真实感方面发挥着重要作用。逼真的云生成是一项具有挑战性的任务，它涉及建模、逼真渲染和云模拟等过程。为了这些目的，在过去的 4 年里，CG 社区中提出了几种技术，重点是上述一个或多个。现代硬件的发展也促进了能够以交互式帧速率实现云显示和动画的技术的发展。在本次调查中，我们回顾了该领域的杰出工作，并总结了研究随时间的演变。
