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.

Set of Procedurally Generated Efects
Barvíř, Marek ; Milet, Tomáš (referee) ; Starka, Tomáš (advisor)
This bachelor thesis deals with creation of a library for procedural generated effects. The paper describes techniques used for creating effects such as: laser, electric arc, energetic shot and shield. The result is a demonstration application which uses designed libraries with pre-prepared scene.

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.

Rendering "Small" Plants in 3D Space
Řehánek, Jiří ; Přibyl, Jaroslav (referee) ; Herout, Adam (advisor)
This masters thesis deals with a real-time low vegetation rendering in 3D space. The low vegetation means grass and shrub. At first it looks on a implementation of vegetation in a 3D games that already exist and there investigate characteristics notable while playing and after that it comes to a evaluation of visual qualities. As next will follow design of solution of this problems and description of implementation. In final part will be summary of achieved product.

Performance Evaluation of Graphics Accelerator
Vanek, Juraj ; Jošth, Radovan (referee) ; Herout, Adam (advisor)
This paper deals with possibilities and functions of modern graphic accelerators and with measuring performance under OpenGL interface. Widespread algorithms to render scene in real-time are used. It focuses on how to test every part of accelerator's graphic pipeline as well as measure performance in rendering of advanced effects and theoretical speed at general purpose calculations through graphic processor. This testing is realized by implementing multiple test series and their further evaluation. Final application enables setting of test parameters and outputs a score, by which is possible to judge accelerator's performance in comparison among themselves.

Debugging Tool for Shaders
Konečný, Jiří ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This thesis deals with implementation of a debugging and development tool for GLSL shader programming. In the text, you will find design of the application and it's implementation in Qt library. The thesis also includes performance testing with GLSL shaders. Experiments were focused on commands of application control flow in GLSL and texturing commands used in shaders. In the thesis, you will find explanation of the functionality of some shaders used in OpenGL. Application developed in this thesis, is meant to help with implementation of graphic programs programmed in OpenGL 3.3 or higher.

Light Propagation Volumes
Růžička, Tomáš ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
The aim of master thesis is to describe different calculation of global illumination methods including Light Propagation Volumes. All three steps of LPV calculation are widely described: injection, propagation and rendering. It is also proposed several custom extensions improving graphics quality of this method. Two parts of design and implementation are focused on scene description, rendering system, shadow rendering, implementation of LPV method and proposed extensions. As conclusion, measurement and several images of application are presented, followed by comparison in environment with diffenent parameters, thesis summary with evaluation of achieved results and suggestions of further improvements.

GPU Raytracer for OSG
Kantor, Jiří ; Horváth, Zsolt (referee) ; Starka, Tomáš (advisor)
This work describes creation of a simple raytracer for OpenSceneGraph, which performs its operations on the graphics card. Things, that needed to be done in OpenSceneGraph in order to pass data to the GPU and also several ray-triangle intersection methods, are described in this work.

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.
