Ocean Wave Simulation near the Seashore

In order to realize real-time simulation of ocean surface near the seashore, a new modeling method for shallow ocean wave and a level of detail （LOD） scheme are proposed in this paper. This modeling method describes ocean wave by modifying the sine wave, and gets wave direction at any ocean floor position by using wave number decomposition. The LOD scheme is proposed to realize real-time rendering of large-scale ocean surface by simplifying the ocean surface regular mesh based on real-time optimally adapting meshes （ROAM）. Experimental results show that this method can get fast rendering speed and realistic effect.
