Rendering Biliard Balls Using Distributed Ray Tracing
Krivda, Marian ; Juránek, Roman (referee) ; Herout, Adam (advisor)
This thesis is concerned in the method of realistic rendering using a distributed raytracing. This method simulates various visual effects and generates high realistic 2D images. The work analyses the problem and explains principles of solution related to this technique. There is also descriprion of the method of simple reytracing which provides a basis for the distributed raytracing. A part of work is specialized for optimalization of distributed raytracing.

Distributed Ray Tracing in Reasonable Time
Slovák, Radek ; Polok, Lukáš (referee) ; Herout, Adam (advisor)
This thesis deals with the method of distributed ray tracing focusing on optimalization of this method. The method uses simulation of some attributes of light by distributing rays of lights and it produces high quality and partly realistic images. The price for realitic effects is the high computational complexity of the method. The thesis analysis the theory connected with these aspects. A large part describes optimalizations of this method, i.e. searching for the nearest triangle intersection using kd-trees, quasi random sampling with faster convergence, the use of SSE instruction set and fast ray - triangle intersection. These optimalizations brought a noticable speed - up. The thesis includes description of implementation of these techniques. The implementation itself emphasises the practical usability including generating some advanced animations and universal description of objects.

Distributed Ray Tracing
Slovák, Radek ; Jošth, Radovan (referee) ; Herout, Adam (advisor)
This project describes method for global display of distributed ray tracing. The method generates high quality and realistic two-dimensional images from mathematical specification of scene. The methods for solution of this issue are presented and analyzed. Integral part of this method - conventional ray tracing - is also presented.

Rendering of Voxel-Based Scenes Using Real-Time Ray Tracing
Menšík, Jakub ; Milet, Tomáš (referee) ; Matýšek, Michal (advisor)
The aim of this work was to create a program to visualize voxel scenes in real time using ray tracing. It included the study of various methods of such a rendering with a focus on shadows. The solution was created using Unity engine and experimental packages Unity Jobs and Burst. The thesis presents multiple ray tracing passes and SVGF technique, that is used to turn a noisy input into full edge-preserving image. The final program is able to render hard shadows, soft shadows, and ambient occlusion at speed of fifty frames per second.

Programmable Shaders in OpenGL
Radil, Přemek ; Havel, Jiří (referee) ; Švub, Miroslav (advisor)
OpenGL is mostly used in video games, computer aided designs, virtual reality, flight simulations or scientific visualisations. This bachelors thesis puts mind to production of shaders written in OpenGL Shading Language and their attachment to OpenGL aplications. Its objective is to describe methods of creating depth of field, glow and soft shadows effects and to provide tutorial about these methods. First chapters informs about OpenGL and associated library OpenGL Utility Toolkit and illustrates some common procedures necessary to achieve hereinbefore mentioned effects. Last chapters dwells directly on shaders creating these effects.

Shadow Mapping: Shadow Filtering in OpenGL
Maresz, Šimon ; Polok, Lukáš (referee) ; Kobrtek, Jozef (advisor)
This thesis deals with filtration of shadow rendering in 3D scene with a focus on quality of rendered shadows. As part of this work was to create a sample application that implements the chosen algorithms that modifies the Shadow Mapping algorithm to render softer and more realistic shadows. The program was created in the integrated development environment Microsoft Visual Studio 2010 in C++. At the beginning the algorithms are explained for rendering of shadows. The conclusion is then engaged in testing and comparing of achieved results.
