With the practical ocean surface and many random aspects of ocean surface, two practical ocean wave algorithms are presented, one of which is based on summing up large numbers of sine waves with amplitudes, and the other is based on the above-mentioned method with the Fast Fourier Transforms (FFTs) and a spatial spectrum function equation,which is applied to build a fairly realistic nonlinear waves. Finally, the results of ocean wave simulation are given.
