Modeling and Simulation of Shallow Ocean Wave Based on Small Amplitude Wave Theory

A new model for shallow ocean wave simulation was proposed based on small amplitude wave theory.This model got shallow ocean wave with peaked crest and curled shape by modifying small amplitude wave.After analyzing the movement characteristics of shallow ocean wave,a calculation method was given about wave altitude and wave numbers. Then,a wave direction calculating method based on phase decomposition and accumulation was proposed for solving the wave refraction under any shallow ocean floor conditions.Simulation results show that the methods can get fast rendering speed and realistic effect,which can be applied in real-time visual scene simulation.
