摘要：We describe a method of using computer graphics to represent the flow of a river in real-time. As rivers are usually narrow and long, the water surface can be seen in detail only in the near view, but it cannot be seen as clearly from a distance. Therefore, the level of water wave model should be dynamically changed on the basis of the distance from the viewpoint. In the near view, the water wave and the reflection at the riverbank can be seen, but this is impossible from the far view. However, the changes in direction of the wave caused by wind can be seen even in the far view. We also propose a method of generating patterns of waves caused by wind. We applied our method to simulations of a landscape and clarified the behavior of a river in real-time.
