Abstract

In this paper, we describe the practical application of several empirically-based, directional ocean wave spectra for use in the Fourier synthesis of animated ocean height fields. We use the Texel MARSEN ARSLOE (TMA) empirical model for the non-directional component of the wave spectrum, and compare a selection of empirically-based directional spreading functions. Additionally, we introduce a novel, normalized parameter called "swell" which modifies the directional spreading to produce wavelength-dependent elongation of waves into parallel wave trains.

This paper builds upon the spectral ocean synthesis techniques popularized for computer graphics in Jerry Tessendorf's popular SIGGRAPH Course, "Simulating Ocean Water" and the accompanying course notes. The advancement of our spectra over the spectrum described by Tessendorf is that it readily gives plausible, attractive results for a wide range of wind speeds, ocean depths, and other physical parameters, without requiring artists to manually adjust gain and filter parameters to compensate for model inaccuracies. Our "swell" parameter additionally provides an intuitive interface for smoothly varying between choppy seas due to local storms and swells from distant weather events.
