Saturn's ring Système makes the planet one of the most beautiful objects in the solar Système. It was difficult to reflect it's beauty by computer simulation, but after a lot of experiments on cutting edge of modern 3D technologyies we have reached the target of really photo-realistic simulated animation of this spectacular scene. Ring's shadows, incredible cosmic sunrises, atmospheric refraction and many other features makes the each single frame of endless smooth animation comparable with best NASA photos!
