Methods of Realistic Rendering
Veselý, Ivo ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
This thesis deals with possibility of operation of realistic graphics on commonly used technical equipment. There are discussed methods of realistic rendering for the purposes of the thesis. Especially the method of Ray tracing. The acceleration techniques and abstractions of reality are explained. They are necessary for real-time running such a time-consuming system. The bounding volume hierarchy is hardly discussed. A part of the text is also focused on additional techniques for scene building and for material characteristics of models. There is a section focused on lighting models because of lighting lets us to see things. Great part of thesis is focused on techniques of connecting standard rendering methods and details computed independently at software. On the other hand there are mentioned alternative techniques that are considered as possible future move.

Ray-tracing Using IPP Library
Kukla, Michal ; Havel, Jiří (referee) ; Hradiš, Michal (advisor)
Master thesis is dealing with design and implementation of ray-tracing and path-tracing using IPP library. Theoretical part discusses current trends in acceleration of selected algorithms and also possibilities of parallelization. Design of ray-tracing and path-tracing algorithm and form of parallelization are described in proposal. This part also discusses implementation of adaptive sampling and importance sampling with Monte Carlo method to accelerate path-tracing algorithm. Next part is dealing with particular steps in implementation of selected rendering methods regarding IPP library. Implementation of network interface using Boost library is also discussed. At the end, implemented methods are subjected to performance and quality test. Final product of this thesis is server aplication capable of handling multiple connections which provides visualisation and client application which implements ray-tracing and path-tracing.

Realistic Rendering of a Building with Varying Lighting Conditions
Navrátil, Jan ; Seeman, Michal (referee) ; Herout, Adam (advisor)
This paper is focused on realistic rendering of interior environments with varying lighting conditions. It proposes methods of setting properties of light sources to achieve a specific scene appearence. It mainly works with light comming from a sky and sun to the scene and describes this light in relation to weather conditions, time of day and overcast factor. The goal is creating easily configurable system in which a single parameter change leads to significant change of lighting conditions. All these changes should be presented in a short video.

Parallelization of Ray Tracing
Čižek, Martin ; Juránek, Roman (referee) ; Herout, Adam (advisor)
Ray tracing is widely used technique for realistic rendering of computer scenes. Its major drawback is time needed to compute the image, therefore it's usually parallelized. This thesis describes parallelization and ray tracing in general. It explains the possibility of how can be ray tracing parallelized as well as it defines the problems which may occur during the process. The result is parallel rendering application which uses selected ray tracing software and measurement of how successful this application is.
