Abstract :
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.
