对海浪波面位移模型的建模方法进行了研究,利用Phillips谱分析方法,建立了受风场和海底地形等因素影响下的海浪波面位移模型,提出了2D FFT的优化方法,提高了计算机的执行效率,解决了海浪数字仿真中的动态数据生成问题,并最终实现了不同分辨率海浪模块的拼接和渲染。
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.
