We've modelled open-ocean waves in OpenScene, the stealth used in the
upcoming STOW exercise. The approach is fairly straightforward: model
the ocean as a gride and the surface spectra as the sum of sine
waves. Every frame calculate the amplitude at each point in the
grid. Animate vertices using pfCycleBuffers.

Of course, the details are more involved (e.g., dealing with level of
detail in the surface grid while maintaining a tri-strippable
surface.)
