Graphics Intro 64kB Using OpenGL
Meixner, Ivo ; Vlnas, Michal (referee) ; Milet, Tomáš (advisor)
Cílem této práce byla implementace a popis grafického intra pomocí OpenGL, s velikostí spustitelného souboru do 64 KiB. Vzniklý program vykresluje 3D animaci imitující přírodní prostředí pomocí kombinace různých technik do jedné scény. Intro bylo implementováno pro spouštění na Microsoft Windows s využitím simplexního šumu, L-systémů a mnoha shaderových programů napsaných v GLSL, včetně compute shaderu pro zpracování instrukcí L-systémů. Výsledná velikost spustitelného souboru je nižší než 8 KiB. Tento program je schopen vykreslovat jednoduchou scénu na styl přírodního prostředí s hornatým terénem, řídkou vegetací, vodními plochami odrážejícími okolní scénu a oblohou měnící se v průběhu dne.

Simulation of Water Waves in Real-Time
Pilch, Martin ; Polok, Lukáš (referee) ; Herout, Adam (advisor)
Task of this thesis is creation of real-time simulation of the water waves. It is implemented on Mac OS X platform using OpenGL. This thesis is based on height map surface. Heigh map is computed by suming of sinusoids with complex, time-based amplitudes. Fast Fourier transformation, Phillips spectrum and gauss random generator are used to solve this problem. The thesis is also implemented on iOS platform and optimized to run on mobile devices thanks to using programmable graphic pipeline and other drawing and computing optimizations.

3D Volume Rendering Data Visualization
Kazík, Jiří ; Švub, Miroslav (referee) ; Kršek, Přemysl (advisor)
Theoretical part of this project is focused on rendering of volumetric data. It compares and appraise individual methods and thus readers get a good basic knowledge of commonnest causes of problems. Texture Mapped Volume Rendering and Volume Ray-casting methods are described in detail and the latter method is used in implementation of graphic system designed in this thesis. Secondary goals of this work are usage of less powerful hardware for volume-rendering, methods of optimization and dynamic change of output quality.

Physics Simulation for Pinball Game
Čermák, Jakub ; Polok, Lukáš (referee) ; Zachariáš, Michal (advisor)
The objective of this work is to create a library for physical simulation and using the library to create a game of pinball, on which you can test functionality of the library. Problems that appeared during the creation of the library, are described in this paper along with their solutions. In particular, tunneling, detection and results of collisions. Subsequent optimization solutions to these problems for our specific library. Of no smaller importance are principles which reduce the requirements of the final simulation. Among the most important ones are the correct choice of limits, detection of rolling and sleep of slowly moving dynamic objects.

Visualization of Large Graphic Data
Ďurica, Peter ; Chlubna, Tomáš (referee) ; Vlnas, Michal (advisor)
This thesis solves visualization of large, specific and specialized graphic data used in science field like point clouds, heat-map on objects in scene or harmonic functions on hemisphere. The work uses the Python language for rendering scenes and the GLSL language for the implementation of heat maps and harmonic functions. The final program can render scenes from Mitsuba renderer with thousands of points in real-time. Heatmaps have 2 types of rendering and that are per pixel and per vertex on objects. Harmonic functions have different quality options for performance control. The main benefit is easier scene analysis thanks to visualization of large data of specific type in real time.

Simple Game Engine
Štefáček, Michal ; Vlnas, Michal (referee) ; Starka, Tomáš (advisor)
Použití herního enginu značně urychluje proces vývoje her. Za posledních několik desetiletí vzniklo množství zdarma použitelných herních enginů, z nichž některé mají volně dostupný zdrojový kód. Cílem této práce je pochopení procesu vývoje takovéhoto softwaru. Pro zúžení rozsahu se projekt primárně zaměřuje na vývoj 2D her.

GLSL Based Engine
Šlesár, Michal ; Karas, Matej (referee) ; Milet, Tomáš (advisor)
Creating a graphical application running on a GPU typically involves configuring the GPU, creating and configuring the required objects, and then implementing the application's behavior itself. The aim of this work is to create a tool that would automate this configuration using the OpenGL application interface. As a result, the user would not have to waste time configuring and could quickly create and prototype graphics applications. In addition, the created tool adds new functionality to the application that is not native or supported on the GPU, such as working with a mouse and keyboard.

Light Field Particle Effects
Škvařil, Jan ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
The goal of this thesis is to propose and implement a method combining light field and particle effects. Particles are rendered as billboards and their textures are created with synthetic light field, which is dynamically generated at runtime. Particles can also use several of these textures at the same time. The thesis also includes several implemented scenes demonstrating various functionality and measurements comparing proposed method with standard 3D rendering techniques.

Terrain Generation and Adjustement
Oplatek, Tomáš ; Matýšek, Michal (referee) ; Starka, Tomáš (advisor)
The goal of this thesis was to create an application, which allows the end user to generate any area on earth as a 3D map, which they could look at and get to know, before they set out on a journey there. The application was developed as a desktop application in the C++ language with the use of OpenGL to render the result and Qt framework for user interface. Added value of this application is, that it allows to set for example the density of vegetation, so that small paths, that are usually hidden are visible and it provides real paths even in lesser known areas.

Collision Detection in Computer Graphics
Stupka, Filip ; Starka, Tomáš (referee) ; Pečiva, Jan (advisor)
This thesis is focused on the problem of collision detection between math defined primitive models and also on triangle networks that form complex polygonal models. Simulation of collision detection is very complex topic from performance standpoint and even though multiple methods that solve these problems do exist, in most cases they are too slow to be any useful and therefore it is encouraged to find optimizations and alternate solutions. In order to be able to work with collision simulation we need to understand discrete and continuous movement techniques and we need to be able to predict behavior of certain objects. This thesis therefore is based on game engine development, optimizations and implementation of collision detection algorithms.
