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.

Complex Scene Rendering on Mobile Devices
Matýšek, Michal ; Polok, Lukáš (referee) ; Kajan, Rudolf (advisor)
This thesis presents optimization techniques for efficient rendering of complex scenes on mobile devices. The introductory part of the text describes Unity game engine and the topic of mobile game development using this tool. Then follows a presentation of important optimization principles and methods for terrain rendering, large scale rendering of animated objects, rendering of animated water surfaces and of other elements in the scenes. The described methods include both general principles of optimization and specific optimization approaches based on the features of Unity game engine. The implementation of presented methods is described and used in practice in the context of mobile strategy game development.

Methods for Alias-Free Shadows Rendering
Posolda, Jan ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This paper concerns aliasing removal methods during the shadow displaying. Method of shadow mapping, its principles, procedure and mainly its drawbacks in the form of aliasing development are described. For the removal of this undesirable phenomenon, several aliasing suppressing methods are described - Percentage Closer Filter, Variance Shadow Map, Convulotion Shadow Map, Exponential Shadow Map a Bilateral Filter. I conclude my work with a proposal and implementation of a demonstrative application, which demonstrates the implemented results adequately. Also, the comparison of individual methods on the basis of their quality and computational demands is included.

Doom-Style Game
Rakus, Roman ; Vyskočil, Michal (referee) ; Pečiva, Jan (advisor)
Usage of effects in computer games is huge. Emphasis is put on the nicest pictures for the lowest price. The newest graphical adapters and technologies are used. In this thesis is described and implemented procedure how to create some effects such as particle systems, per-pixel lighting, normal bump mapping and fake volumetric lines with usage of OpenSceneGraph, shaders and others.

Advanced Rendering Techniques in OpenGL 2.0
Salajka, Vojtěch ; Havel, Jiří (referee) ; Švub, Miroslav (advisor)
This thesis deals with the interactive computer graphics on programmable hardware. The usage of shaders for creation of graphic effects is demonstrated by examples. It is explained how to use OpenGL library and GLSL language for their implementation. A new 3D model format was developed for the purposes of the examples.

Shader Demonstration Using OpenSceneGraph and QT Libraries
Harman, Peter ; Bartoň, Radek (referee) ; Švub, Miroslav (advisor)
Assignment of this work is to zoom in the work with vertex and fragment processor for users. Programs for these processors are called vertex and fragment shaders. They may be written in a various programming languages intended for them (HLSL, Cg...), however in the work is going to be discussed OpenGL Shading Language (GLSL). There are going to be demonstrated this techniques of advanced rendering: Phong shading, Blinn-Phong shading Lambert illumination, Gouraud shading Later on is going to be described work with library OpenSceneGraph, as a library based on OpenGL and its integration with library for generating user's interface. The result is going to be a multiplatform application demonstrating connection between QT and OpenSpaceGraph libraries with integrated tutorial describing whole process of implementation. Theoretical background is going to be included as well.

Physically Based Shading
Matěj, Šimon ; Lysek, Tomáš (referee) ; Starka, Tomáš (advisor)
This thesis deals with imaging of materials in computer graphics, using rendering methods based on physical properties of these materials. Physical principles of light propagation and its interactions with objects are analyzed, several rendering methods based on these principles are described and then analyzed for suitability in implementations. Some of these methods are demonstrated in application.

Graphics Scene Visualization Using OGRE Library
Ondrejíček, Marián ; Navrátil, Jan (referee) ; Pečiva, Jan (advisor)
The goal of this thesis is to investigate the possibilities of the OGRE visualization library and to implement an application which utilizes both simple and advanced OGRE features. Furhtermore there are explained basics of creating effects using Cg language and connecting them with OGRE library. The Bullet library which is often used in visualization applications for physics calculations is analyzed as well. The second part describes implementation of the demo application. In the end, the results are discussed, including possibilities of future development.

Vertex and Pixel Shaders OpenGL Visualisation of Medical 3D Image Data
Vaďura, Jiří ; Španěl, Michal (referee) ; Kršek, Přemysl (advisor)
This thesis deals with accelerated 3D rendering of medical data, e.g. computed tomography, using a graphics processor and OpenGL library. Raw data slices are send to graphic memory and rendered by a ray-casting algorithm. The goal of this project is high quality visual output and full user interaction at the same time. Multiple rendering modes are avaiable to the user: MIP, X-Ray simulation and realistic shading.

Visualization of 3D data in biomedical applications
Karzel, Michal ; Harabiš, Vratislav (referee) ; Štohanzlová, Petra (advisor)
This thesis describes the basic principle of optical coherence tomography and prepro- cessing of the measured raw data. Preprocessing is focused mainly on noise filtration, removing artifacts, normalization, conversion and compression of raw data. In this way preprocessed data is saved in a *. PFRG file as ”preprocessed fringe data”. Those pre- processed data will be visualised by simply software, which support three methods of visualisation. Volume data represented by voxels. Reconstruction of volume by marching cube algorithm. Cuts through volume along X, Y and Z axis.
