Clouds play an important role when creating realistic images of outdoor scenes. One of the most effective approaches for synthesizing realistic clouds is to simulate the cloud formation processes based on fluid dynamics. However, the resulting shapes of clouds depend on many simulation parameters. Therefore, it is difficult to adjust those parameters so that the clouds form the desired shapes. This paper presents a new method for controlling the simulation of cloud formation. Although there are various types of clouds, we focus here on cumulus clouds. By using our method, cumulus clouds that change into specified shapes can be animated without repeating simulations using various parameter-values determined by trial and error.
