The paper discusses various aspects of the waved water surface and underwater bottom video representation simulation and also expands on the math models and algorithms of the following related tasks: waved water surface simulation; calculation of reflected and refracted rays directions in 3-D space; underwater caustics (extra illuminated areas) forming; refractive distortion of the bottom view account; reflected skylight addition.

I'm a physicist but I haven't understood in which connection water temperature differentials are here. Gravity waves simulation and geometrical optics only.
