摘要：Displaying clouds is one of the important factors in creating images of outdoor scenes by using computer graphics. Methods based on fluid simulations are often used since they can simulate realistic cloud movements and shapes. However, although this approach can create realistic clouds, the resulting shapes and motion depend on many simulation parameters and their initial status. Therefore, it is very difficult to create the clouds of desired shapes. In this paper, we propose a method for generating clouds with shapes that users have specified. The user specifies the multiple shapes of the clouds at several key frames. Then our method automatically adjusts parameters during the simulation in order to generate clouds forming the specified shapes. Using the proposed method, clouds that change into specified shapes can be animated.
