Title: Atmospheric Rendering Author: Mgr. Lukáš Hošek Department: Department of Software and Computer Science Education Supervisor: doc. Dr. Alexander Wilkie, Department of Software and Computer Sci- ence Education Abstract: The sky is an important feature of all outdoor scenes. This thesis explores the topic of skydome models - an approach to getting the sky and atmospheric effects integrated into a renderer. We discuss the physics of atmospheric scattering and de- scribe in detail the construction of a first-principles path tracer atmospheric simulator implementation. The presented path tracer is fully spectral and produces polarization data. Finally, we present two different analytic skydome models. These analytic mod- els are highly practical because they can be integrated even into real-time renderers and provide an excellent combination of fidelity and low computational cost. The first model is a simpler version, providing just the skydome spectral radiance. The second model also provides polarization data, after-sunset skies with an accurate modeling of Earth's shadow, aerial perspective and full sphere data. Keywords: computer graphics, rendering, skylight models, atmospheric modeling
