Algorithm Acceleration on Larrabee Platform
Veselý, Ivo ; Seeman, Michal (referee) ; Zemčík, Pavel (advisor)
Intel Larrabee is one of the first of fully programmable graphical architectures. Thesis describes this many-core architecture by hardware implementation and programmer's model point of view. Larrabee bets on many complete in-order cores, built over x86 instruction set. Cores contains four hardware threads, each with it's own register file, and new vector processing unit. Vector processing unit together with instruction set extension rapidly increases system performance. New cache modes helps to increase throughput even when irregular data structures. This architecture is not focused only on computer graphics nor image processing, but all parallel tasks. Second part of this text deals with hologram synthesis. Specifically, it brings two new methods for patch of point light sources generation with concrete radiation.

Languages and Compilers in Computer Games
Hranáč, Jan ; Zuzaňák, Jiří (referee) ; Zemčík, Pavel (advisor)
This project deals with usage of programming languages and compilers in computer games. Purpose of this project is to give young people motivation for programming, which isn't always done by usual work in Pascal at high school. This idea was applied on a developed computer game with has a few integrated languages which can be used for creation of the game's content (adventures, campaigns and objects in them). This computer game was based on a RPG desk game Dragon's Lair (a Czech equivalent of D&D) from ALTAR(TM) publishing company.

Estimation of Object Parameters from Images
Přibyl, Bronislav ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
Rapid expansion of communication technologies in last decade caused increased volume of information which is beeing generated and shared by people and organisations. It is permanently harder to identify relevant content today because of absence of tools and techniques which may support mass information management. As today's media have rather multimedial character image information is even more important. This project describes software for automatic estimation of predefined object parameters from images. A C++ implementation of this algorithm is also described.

Optimized Ray Tracing
Brich, Radek ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
Goal of this work is to write an optimized program for visualization of 3D scenes using ray tracing method. First, the theory of ray tracing together with particular techniques are presented. Next part focuses on different approaches to accelerate the algorithm. These are space partitioning structures, fast ray-triangle intersection technique and possibilities to parallelize the whole ray tracing method. A standalone chapter addresses the design and implementation of the ray tracing program.

Optical Field Calculations in GP-GPU
Srnec, Erik ; Polok, Lukáš (referee) ; Zemčík, Pavel (advisor)
This work describes a relatively new technique designed to write highly parallel programs, that name is OpenCL. It is intended for both GPU and CPU and other parallel processors. Libraries used by the processor architecture, which includes a large number of small cores. These cores are not as comprehensive as conventional processors and is therefore suitable for calculations, which are many and they are simple. It is this property could, under certain conditions, accelerate the calculation of the hologram, namely the calculation of the optical field. While the calculation itself is simple, but the amount of processed data is large and therefore slow. The work also contain the basic concepts of explanation of optical and digital holography.

Analysis of General Polygon Boolean Operation Algorithms
Daněk, Tomáš ; Zemčík, Pavel (referee) ; Beran, Vítězslav (advisor)
This thesis deals with general polygon boolean operation algorithms. Boolean operations are e.g. intersection, union or difference. A general polygon can be e.g. a selfinterecting polygon with inner hole. Clipping of polygons against a rectangular window is probably the most familiar boolean operation on polygons. At first, basic definitions are listed. Then the principles of a selected set of boolean operation algorithms are reviewed. Finally, a complex comparison of the algorithms is undertaken. Performance as well as the ability to handle degenerate cases are tested. The output of this thesis is an overall evaluation of algorithm properties and a dynamic library that contains the implementation of all of the tested algorithms.

Visualization and Modelling of Molecules and Crystalles
Bubník, Václav ; Chudý, Robert (referee) ; Zemčík, Pavel (advisor)
Aplikace pro vizualizaci a modelování molekul nejsou dosud příliš poznamenány současným hardware vyvinutým pro potřeby počítačových her. Cílem projektu je navrhnout intuitivní rozhraní s novými widgety specializovanými na atomové struktury a vizualizací využívající moderní hardware grafických karet. Důležitou částí je také dosažení vysoké přesnosti modelování, obvykle dostupné pouze u profesionálních CAD programů.

Development of 3D Applications in Blender
Opletal, Martin ; Láník, Aleš (referee) ; Zemčík, Pavel (advisor)
Thesis is focused on evaluation of available tools for 3D application development. In one selected tool (Blender) is created computer game. This game demonstrates Blender's capabilities. The process of creating is recorded in a case study for the possible purposes of own complex games development.

Online Business Cards Generator
Turic, Matúš ; Zemčík, Pavel (referee) ; Beran, Vítězslav (advisor)
Vizitky jsou stále nedílnou součástí marketingu. Vizitka představuje snadný způsob výměny základních kontaktních informací mezi jednotlivci. Tato bakalářská práce se zabýva popisem a tvorbou webové aplikace, pomocí níž si bude každý moci vytvořit vlastní vizitku podle předem připravených šablon. Výsledkem webové aplikace je PDF soubor s vytvořenými vizitkami.
