3D Game World in OpenGL
Buchta, David ; Lysek, Tomáš (referee) ; Milet, Tomáš (advisor)
Focus of this master's thesis is a study of modern techniques in computer graphics and designing and developing custom application based on which could be developed new game engine. In this thesis are highlighted techniques for creating large terrains, advanced shadows, physically based sky rendering and drawing large set of objects. Finally, performance testing of these modules is performed.

Rendering Using Deep Shadowmaps
Hypský, Jan ; Kobrtek, Jozef (referee) ; Polok, Lukáš (advisor)
In computer graphics is problematic shadow rendering. Applications require to choose the appropriate lighting and shading method with respect to speed and display quality. This work is focused on rendering the shadows and eliminate alias, arising during their creation. For to create shadows will work to implement the methods Shadow Maps and she's extensions variant Deep Shadow Maps. Shadow maps allow to create shadow independently of the scene complexity without treatment alias. Deep shadow maps are able to display shadows along with the removal of alias thereby improve the quality of shading. For lighting scene are used local Lambert lighting models. The resulting application is created with using library OpenGL.

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.

Shadow Rendering through Translucent Materials
Mátl, Roman ; Havel, Jiří (referee) ; Navrátil, Jan (advisor)
This paper describes the calculation of shadows through translucent materials using a method called Colored Stochastic Shadow Maps and its practical implementation in OpenGL libraries. At the beginning of this work a Shadow mapping method is introduced. The next section shortly describes selected ways of dealing with rendering of transparent objects in the scene. This is followed by detailed explanation of the method Colored Stochastic Shadow Maps. The last section describes the implementation of demonstration application in C++ language, evalution of the results and proposal of options to continue the project.

Methods for Soft Shadows Rendering
Ondruška, Jiří ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This thesis discusses two different methods for creating soft shadows. Shadow volumes and shadow mapping, more accurately Variance Soft Shadow Mapping. It presents theory for these shadow algorithms as well as theory for few others which are necessary for understanding. Further it describes how to implement these methods and evaluates these implementations. Shadow volumes are based on creating additional geometry to the scene which serves for specifying region of penumbra. VSSM algorithm is a improved version of classic shadow mapping.

Methods for Alias-Free Shadows Rendering
Posolda, Jan ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This paper concerns aliasing removal methods during the shadow displaying. Method of shadow mapping, its principles, procedure and mainly its drawbacks in the form of aliasing development are described. For the removal of this undesirable phenomenon, several aliasing suppressing methods are described - Percentage Closer Filter, Variance Shadow Map, Convulotion Shadow Map, Exponential Shadow Map a Bilateral Filter. I conclude my work with a proposal and implementation of a demonstrative application, which demonstrates the implemented results adequately. Also, the comparison of individual methods on the basis of their quality and computational demands is included.

Real-Time Illumination of a Scene
Martanovič, Lukáš ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This thesis is focused on describing methods of computation of global illumination of 3D graphics scenes in real-time. First chapter contains brief introduction to the issue of global illumination (GI) computation, as well as quick summarisation of principles of most commonly used GI computation approaches. A method of visibility computing for indirect illumination, taking advantage of Imperfect Shadow Mapping, is introduced next. After closer examination of this method and prerequisite algorithms follows a description of its practical implementation, as well as of the structure of simple demonstrative application. Next chapter then contains testing and brief examination and evaluation of resulting program's behaviour. Finally, a possible method extension by means of virtual point light clustering is proposed.
