基于频谱的湍流函数海浪仿真

针对海浪仿真的物理模型都非常复杂，还没有简单的方法来实时描述动态海浪．文中提出一种可以实时描述深水动态海浪的简单方法，通过真实的海浪频谱控制三维次摆线，产生海浪模型之后叠加j维湍流函数来描述细节．这种方法建立的海浪模型在频域非常接近于真实的海浪频谱，在时域中可以得到比较真实的海浪形状．

Simulation of ocean wave using a spectrum-based turbulence function

Until now, the physical models for simulation of ocean wave are all very complicated. No simple method is available that can describe the ocean wave dynamically on real-time. In this paper, a simple approach was proposed to describe the wave dynamically in deep water. The wave model was generated by using real frequency spectrum of ocean wave to control the 3-D trochoids. Then a 3-D turbulence function was superposed on it to describe the second level of details. Since the synthesized ocean wave spectrum approaches a real ocean wave spectrum, real water waves can be obtained in the time domain.
