Coastal Landform Generation Based on Particle Method and Mathematical Geography

Abstract

This paper propose a coastal terrain generation method based on a particle method and mathematical geography. The terrain generation is one of the important topic for computer graphics field and we focus on the coastal landform generation. In order to simulate the generation of coast, we have to consider a ocean wave. Most of previous terrain generation methods adopted simple water flow simulations to calculate the erosion, while it is difficult to accurately simulate the ocean wave because of its scale and its complex flow. Our method uses a low dimensional particle method to calculate the movement of the ocean wave and mathematical geography to simulate the change of terrain due to the wave. As a result, we archived a fast terrain generation for rock and sand coast.
