Optimized Ray Tracing
Trojan, Martin ; Polok, Lukáš (referee) ; Zemčík, Pavel (advisor)
This thesis deals with optimization methods for ray tracing. There are discussed several methods of acceleration structures and method for reducing the complexity of calculating intersection with complex objects. Part of the text also deals with the ray tracing method and the concepts associated with this technique. For the purposes of this thesis have been created application, which is implemented ray tracing algorithm using a uniform grid for optimization.

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.

Photorealistic Rendering of 3D Scenes
Vlnas, Michal ; Milet, Tomáš (referee) ; Zemčík, Pavel (advisor)
This thesis proposes a concept of sampling, especially for path tracing like algorithms, for faster convergence of the scene, using a local radiance approximation in the scene with hemispherical harmonics, which allows more effective way of ray casting on the given surface. In the first part, the basics of photorealistic rendering are introduced together with commonly used algorithms for image synthesis. The mathematical apparatus used in this thesis is defined in the second part of the thesis. Subsequently, existing solutions in this area are presented. The following chapter summarizes state-of-the-art methods in this branch. The rest of this thesis is focused on proposal and implementation of already mentioned extension.

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.

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.

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.

High-Quality Shadow Rendering from Complex Light Sources
Navrátil, Jan ; Sochor, Jiří (referee) ; Navrátil, Jan (referee) ; Zemčík, Pavel (advisor)
V interaktivních aplikacích jsou stíny tradičně zobrazovány s pomocí algoritmu založeným na stínových mapách. Nevýhodou toho algoritmu je, že stínová mapa, reprezentovaná texturou, má pouze omezené rozlišení. To může vést k nepěkným vizuálním artefaktům objevujících se na hranách stínů. Tato práce představuje postup, který je založen na vylepšené deformaci textury. To umožní zobrazit scénu obsahující složité světelné zdroje, zredukovat artefakty na hranicích stínů a také vylepšit kvalitu stínů bez ohledu na typu scény a její konfiguraci.
