the functions are just the ones from school, just many of them summed up and in different scales ;-)

oh, and the foam is actually an illusion. in thin layers (like in the wave crowns) the light gets reflected/refracted multiple times in the same region, which leads to a more random light diffusion in those regions. i was surprised myself by that effect! ...that doesn't mean real waves cannot have foam additionally ;-)
