摘　　要：采用风噪声作为基本模型,模拟海面波动态运动过程。海面波的高度受到海面波平面运动方向的函数影响。海面波的运动可表示成平面的两个方向的函数,这两个函数控制着海面波的高度。海面波在某一时间点截面的高度表示成风噪声函数,再通过主函数的形式把这两个函数对海面波高度的影响进行统一,并采用人工参与的遗传算法对仿真效果进行优化。仿真时采用动画帧的形式形成时间片,产生用户满意的三维海面波动态效果。In this paper, a method to simulate sea water surface waves 3D dynamics based on a wind noise model is addressed. The sea water surface waves motion height is varied by some special functions moving along the sea water horizontal direction. The sea water surface waves may be represented by the two directions functions, which can mainly determine its motion height. At a randoln time, sea water surface waves motion height may be represented by a wind noise model. In addition, the effect of these two functions by the main function may be integrated. Especially, .the optimization measures should be adopted with a genetic algorithm and human interference. In actual simulation, the time slice can be generated by the corresponding animation frames. Finally, the dynamics simulation can meet user＇s demand.
