Claim One:
1. A computer-implemented method for animating the surface of a body of water, the method comprising: obtaining a wave model used to describe wave surfaces in a body of water, the wave model comprised of a range of wave model frequencies over a given area; defining a primary layer model comprised of a set of primary frequencies, wherein the set of primary frequencies represents a portion of the range of wave frequencies described in the wave model; defining a secondary layer model comprised of a set of secondary frequencies, wherein the set of secondary frequencies includes wave frequencies greater than the set of primary frequencies; defining a tertiary layer model comprised of a set of tertiary frequencies, wherein the set of tertiary frequencies includes wave frequencies greater than the set of secondary frequencies; constructing an optimized wave model by combining the primary, secondary, and tertiary layer models; determining a wave surface point location within the given area; determining a wave height value for the wave surface point location using the optimized wave model; and storing the wave height value associated with the wave surface point location.
