The correct color of water and bottom refraction is one of the most important parts of realistic visual water simulation. The paper is devoted to the real time rendering of scenes with shallow water when the bottom is visible. It covers the model of light transport at the water surface and through the water medium that allows us to calculate spectral intensity of light at the surface; the human...
