Rendering Planetary Atmospheres in Real-Time
 Elek, Oskár ; Maršálek, Lukáš (referee) ; Kmoch, Petr (advisor)
In the field of photorealistic rendering of physical phenomena, the rendering of atmospheric light scattering takes a very important place. Realtime rendering of sky and atmosphere in general is essential for all outdoor computer games, various simulators, virtual worlds or even for animated movies. It is a very difficult task, but thanks to the advancement of dedicated graphics hardware we can reach it today. In my thesis I present an accurate and fast method for real-time rendering of planetary atmospheres. This is achieved by precomputing complex single-scattering equations into a set of lookup tables. The correct atmospheric colour values are then fetched from these in the fragment shader. The presented method is then implemented in a program that is capable of rendering realistic atmosphere in hundreds of FPS.
