Ring Discretization of the Wave Spectrum for Sea Surface Simulation

Although interactive computer-generated ocean scenes based on real wave spectra are impressively realistic, they usually don't exhibit the original sea state's statistical properties. This might be unacceptable for applications in which the sea surface height field's correctness is important, such as 3D ship simulators for training professionals. Researchers have developed a discretization of the wave spectrum that obtains a sea state statistically more equivalent to the original. This method can also improve the scene's visual realism and real-time performance.
