| Abstract: | In this paper, the formulation method for ocean wave surface displacement model is studied, and Phillips spectrum analysis method is used to establish the ocean wave surface displacement model affected by the wind field, seabed terrain and other factors. Moreover, the optimization method for 2D FFT isproposed to improve the computer execution efficiency and solve the problem with dynamic data generation in the digital ocean wave emulation, and the paste-up and rendering of ocean wave modules with different resolutions are finally realized. |
