Shadow Volumes in OpenGL
Salvet, Jan ; Pečiva, Jan (referee) ; Havel, Jiří (advisor)
This thesis is focused on one particular method of shadowing in computer graphics. It not only describes basic theory, but also deals with actual implementation using modern OpenGL. It includes performance tests of several versions of this method using a testing application. The results show clear advantage of computing shadows on graphics card.

Graphics Intro 64kB Using OpenGL
Juránková, Markéta ; Havel, Jiří (referee) ; Herout, Adam (advisor)
The aim of the master's thesis is to create a graphic intro with the limited size of 64kB. Brief history of a demoscene and the graphics library OpenGL is introduced in the following text. The main part of the work is a description of minimal graphics techniques used in a creative process and their further application in the final programme.

Shadow Rendering from Omnidirectional Light Sources
Mikulica, Tomáš ; Kobrtek, Jozef (referee) ; Navrátil, Jan (advisor)
This work discusses the possibilities for shadow rendering from omnidirectional light sources using OpenGL library. In this work the Cube map shadow mapping and the Dual paraboloid shadow mapping algorithms are described. Further more, this work contains the results of a comparison of these two methods in a way of time required for shadow map creation and a comparison of visual quality of resulting shadows.

Fast Visualization of Precise Shadows Using Precomputed Scene Geometry
Mikeš, Tibor ; Milet, Tomáš (referee) ; Pečiva, Jan (advisor)
The aim of this bachelor's thesis is to design and implement an effective method of rendering per-pixel correct hard shadows in scenes with static geometry. The principle of the method is in separate rendering of shadowed and lit surfaces. Whether a triangle is in shadow or not is known prior to its rasterization, which allows the renderer to omit per-fragment shadow calculations. Rendering a scene in this way requires it to be preprocessed. Therefore, two possible ways of preprocessing the scenes are described and implemented as well.

Improvements of Shadow Rendering
Kobrtek, Jozef ; Kozlíková, Barbora (referee) ; Váša, Libor (referee) ; Herout, Adam (advisor)
Táto práca sa zaoberá inkrementálnym zlepšením techniky tieňových telies. V práci sa popisuje vylepšenie vykresľovania z pohľadu robustnosti kde bol navrhnutý nový spôsob deterministického výpočtu siluety na rôznych platformách. Táto technika bola v ďalšom kroku zjednodušená a celý algoritmus tieňových telies implementovaný prostredníctvom hardvérovej teselácie. Ďalej bola navrhnutá metóda akcelerovanej extrakcie siluety z modelu pomocou oktálového stromu. Navrhnuté metódy boli v závere porovnané s aktuálnymi modernými algoritmami s tvrdými všesmerovými tieňmi.

Advanced Techniques Demo Using OpenGL
Buček, Antonín ; Přibyl, Jaroslav (referee) ; Herout, Adam (advisor)
This thesis demonstrates advanced techniques using OpenGL. The work is conceived as a demo without any size restrictions. It focuses on creating 3D world, which consists of inner rooms complex. Some additional interesting objects, lighting and shadows enrich the rooms. Particle systems, which were used to create explosions, smokes and some other particle effects are described in the thesis, too. 3D machine models fight between themselves using laser beams and form the story of the demo. Important part of the work is a movement model which is applied to both models and avatar. Sound track completes the demo.
