Three-dimensional computer animation can be very useful in presenting weather forecast on TV channels. However, generation of the animation for weather forecast using general-purpose tools might be difficult and time-consuming since this kind of animation requires special visual effects and various animatable parameters. Furthermore, the animation is to be generated by ordinary users with no training in animation. In this paper, we present a three-dimensional computer animation system specifically designed for presenting weather forecast. The system is designed and implemented using object-oriented techniques that are very helpful for computer animation and motion abstraction. The animation system also incorporates multiresolution modeling and paging of huge terrains for fast rendering.
