Realistic Rendering of Atmospheric Phenomena
 Sabela, Ondřej ; Karas, Matej (referee) ; Vlnas, Michal (advisor)
The aim of this thesis is to develop a GPU accelerated computer program which is able to simulate light scattering in the Earth's atmosphere and clouds using the simplest possible combination of various realistic rendering techniques. A detailed explanation of the physical and phenomenological background of the basic characteristics of both solid and translucent materials is included. Physically based rendering methods which are able to simulate such phenomena are presented along with several optimizations, including precomputation and lookup tables, with a focus on functional fidelity to real-world principles. The presented solution is based on data from real-world microphysical measurements. The resulting outdoor scene images can be used as background environment maps in 3D modelling and design software. The open source code can also serve as a starting point for describing the implementation of the presented rendering techniques.
