Interactive applets supporting teaching digital image processing
Křivánek, Jiří ; Mangová, Marie (referee) ; Rajmic, Pavel (advisor)
This thesis deals with the creation of applications for support of education computer graphics. The aim is to create a simple application which will show the functioning of the various methods. I implemented convolution methods for image filtering, dithering engaged in the distribution errors, bit planes that show each bit plane image, gamma correction to lighten or darken the image and procedural textures. All these methods are created in the form of Java applets.

Real-Time Volumetric Terrain Rendering
Koblížek, Aleš ; Kobrtek, Jozef (referee) ; Matýšek, Michal (advisor)
Tato práce popisuje způsob implementace volumetrického terénu s důrazem na modifikovatelnost v reálném čase. Použitá datová struktura je bitové pole - materiál terénu není potřeba ukládat, takže pro uložení každého vzorku stačí jeden bit. Textura je odvozována na základě sklonu terénu. Vizualizace se provádí převodem na povrchovou reprezentaci pomocí algoritmu pochodující kostky a následným zobrazením polygonové sítě pomocí vykreslovacího řetězce. Terén i textura jsou generovány procedurálně. Pro rozrušení poměrně pravidelného povrchu je použit displacement mapping a teselace. Jemnější detaily jsou získány pomocí bump mappingu. Pro dynamické stíny je použit shadow mapping.

Graphics Intro 64kB Using OpenGL
Burkot, Martin ; Polok, Lukáš (referee) ; Herout, Adam (advisor)
This thesis deals with the creation of minimal graphics intro. Intro size is not extending 64kB. The base of the intro is procedurally generated terrain supplemented with procedural vegetation and texture representing clouds. It also has terrain texture and imported 3D models. As background music is music playing.

Graphics Demo Employing Procedural Textures
Drevický, Dušan ; Matýšek, Michal (referee) ; Polok, Lukáš (advisor)
This thesis deals with the design and implementation of a size-limited 64 kB graphics demo. Procedural generation is used for the definition of structure and appearance of realistic natural terrain. The terrain is described by a heightmap based on noise functions described in this work. Rendering utilizes the ray marching method and is done in real time. All parts of the implementation described in this work were created exclusively within the fragment shader of the GPU.

Procedurally Generated Landscape in Fragment Shader
Leitner, Denis ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
This thesis deals with rendering of procedurally generated landscape without the use of input geometry or textures. It describes techniques for generation and realistic rendering of natural outdoor scenes. These techniques include terrain generation and realistic atmosphere and cloud rendering. Thesis also describes the use of raymarching for terrain and shadow rendering and realistic lighting for terrain which includes ambient and indirect light approximation.

Game in a Shader
Ivanecký, Ján ; Milet, Tomáš (referee) ; Polok, Lukáš (advisor)
This thesis deals with design and implementation of a simple strategic game using OpenGL, whose game logic is realized by the graphics card and rendering is realized by the graphics card in one shader. It also contains introduction to OpenGL, overview of techniques used for generating procedural textures and overview of rendering methods based on Ray Casting.

Procedural Texture Generator
Doroshenko, Ilya ; Karas, Matej (referee) ; Milet, Tomáš (advisor)
Textures are an essential part of modern 2D and 3D rendering. The most prominent texturing techniques are Texture Mapping and Procedural Generation. Both techniques have their set of demands on computational resources. Procedural generation provides rich detail resolution without memory consumption, but also requires processing power. Texture Mapping is quick to process, but images, that the texture consists of are using a lot of space in memory and have finite resolution and sets of complications around algorithms that try to overcome that problem. This thesis discusses techniques of texture generation their interchangeability and applications. Result is an extensible application, that can produce texture maps from algorithms and can export algorithms to be used in procedural shading techniques.

Minimal Representation of the Božetěchova Complex
Piovarči, Rastislav ; Kajan, Rudolf (referee) ; Vlček, Adam (advisor)
The goal of this thesis is to briefly familiarize the reader with damoscene phenomena as a foundation for creation of minimalistic application, which it implements. Then it explains the process of designing and implementation of minimalistic application which displays the Božetechova complex. The aim of this interactive application is to reproduce the Božetěchova complex in the best possible quality using a restricted size binary file. It uses means like procedural textures on the bases of Perlin noise, or multilevel comprimation and instantiating of model geometry to achieve this goal.
