Imitation of breaking waves in coastal zone using 2D profiles

摘要

This paper is dedicated to the imitation of breaking waves in a coastal zone (the zone where wave height is comparable with the depth). The method proposed is aimed at virtual reality applications. It should imitate quite complicated processes of wave transformation, destruction and further propagation; splashes and foam phenomena. At the same time, it has to satisfy computer performance restrictions in real time applications. The paper describes the method of 3D wave shape reconstruction based on 2D profiles, modification to the simulation method in 2D that allows continuing simulation after wave breaking and proposes an algorithm of splashes and foam imitation. The result of this method - real-time simulation of complex phenomenon of breaking wave. The paper contains the algorithm description, performance measurements of its software implementation and 3D waves screenshots.
