摘　　要：近年来,自然景物的模拟一直是计算机图形学中最具挑战性的问题之一。作为自然景物模拟的重要内容,对流水、波浪的模拟正日益引起人们的关注。现有的模拟方法要么从流体力学方程组出发,去求解复杂的Navier-Stokes方程,要么根据波浪的形状,去构造具体的波形函数。本文从海洋学现有的观测和研究成果出发,利用海浪频谱和方向谱的相关公式,实现了基于海浪谱的波浪造型及显示。实践证明该方法可以快速有效的模拟波浪。In recent years, simulating natural phenomena has always been one of the most challenging tasks in computer graphics. As one of its most important parts, simulating water and wave has been given more and more attention. Some existing methods try to solve complex Navier-Stokes equations, and some others try to construct special functions to model the shape of water waves individually. This paper presents a method of wave simulation based on ocean wave spectrums, using the observation and research results of oceanography, such as frequency spectrums and directional spectrums of ocean wave. Our results show that the method is efficient and effective in wave simulation.
