摘要:

本文从海洋学现有的观测和研究成果出发,结合海浪的Gerstner模型,提出一种风力作用下的基于海浪谱的三维Gerstner海浪模型。首先,通过分析Gerstner模型各个参数的随机性,利用海浪谱和方向谱相关公式,获得固定风速下模型各随机参数值,建立固定风速下的海浪模型;然后,在此基础上进一步构造了基于海浪谱的风力模型,模拟了 风力作用下的海浪;最后,采用基于视点的网格拓扑结构,实现了海浪的实时绘制。实验结果表明,该模型不仅能更真实地模拟海浪,还具有较好的交互性。

Abstract:

Starting from the observation and research results of oceanography, combining wttta the 3D Gerstner waves model, we present a Gerstner waves model under wind force based on spectrum. First, on the basis of analyzing all parameters of the Gerstner model, all parameters at a fixed speed can be obtained  from the spectrum, thus the basic ocean waves shape is constructed. Then, a wind model based on the spectrum is established to simulate ocean waves unde achieved. This method not only simulates ocean  waves more truly, but also has better interaction.

Key words: spectrum of ocean waves, gerstner model, ocean waves simulation, wind force model
