Volumetric Clouds
Barvíř, Marek ; Matýšek, Michal (referee) ; Starka, Tomáš (advisor)
This master thesis deals with creation of library for volumetric clouds. The paper describes specific techniques for creation and rendering volumetric clouds as clouds and atmospheric scattering. For rendering this type of effects we have to cover theory for participating media.

Terrain LoD Algorithm Implementation
Radil, Přemek ; Pečiva, Jan (referee) ; Bartoň, Radek (advisor)
This thesis discusses implementation of LoD terrain visualization algorithm Seamless Patches for GPU-Based Terrain Rendering as extension for Coin3D library. It presents procedures which this algorithm uses for displaying large terrain datasets. Entire terrain is composed of patches that are stored in patch hierarchy. Patch hierarchy is traversed during runtime to generate active patches based on observer's position. Each patch consists of predefined tiles and connection strips so it doesn't need to store any geometry. During render of tiles and strips, displacement shader is applied. This thesis also evaluates results achieved in sample application and suggests some modifications to further increase algorithm performance.

Generating Procedural Textures in Shader
Veverka, Pavel ; Navrátil, Jan (referee) ; Polok, Lukáš (advisor)
This work deals with procedural texture generation using programmable graphics pipeline in OpenGL. It describes basics of OpenGL operation and programmable shading. The main contribution is the analysis of methods used for generating procedural textures using various algorithms and noise functions, with focus on Perlin noise. The examples of procedural texture shaders are demonstrated by a C++ application, displaying 3D model of Božetěchova building.

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.

Graphics Demo Employing Procedural Textures
Drevický, Dušan ; Matýšek, Michal (referee) ; Polok, Lukáš (advisor)
This thesis deals with the design and implementation of a size-limited 64 kB graphics demo. Procedural generation is used for the definition of structure and appearance of realistic natural terrain. The terrain is described by a heightmap based on noise functions described in this work. Rendering utilizes the ray marching method and is done in real time. All parts of the implementation described in this work were created exclusively within the fragment shader of the GPU.

Visualization of Tactile and Aural Sensations
Lukš, Roman ; Zachariáš, Michal (referee) ; Polok, Lukáš (advisor)
The purpose of this thesis is to design and implement visualization of aural and tactile sensations in the real-time. Sensations are to replace vision in simple 2D platform game. Visualizations are implemented on GPU. Vizualization of aural sensations implement computationally lightweight explicit method. Vizualization of tactile sensations are implemented as the animated lines. OpenGL is used to draw graphic output. Functional game prototype with vizualization of these two sensations is the output of this thesis.

Graphics Intro 64kB Using OpenGL
Marek, Jan ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
This bachelor's thesis deals with the creation of a graphics intro with a limited size. It deals with methods used for its creation. The thesis describes methods used for reduction of size of executable files. Among them for example the use of prcedural generation and the use of exe packers. The created graphics intro has a size smaller than 64 kB.

Graphics Intro 64kB Using OpenGL
Sykala, Filip ; Polok, Lukáš (referee) ; Herout, Adam (advisor)
Master's Thesis is about the techniques of creating a small executable program with size limited to 64kB. Describes one of the possible ways to use OpenGL for such purposes. With more detail describe the rigid body simulation, creating shaders, dynamic generating of texture and make music in intro scene applications. Presents using of WinApi to create windows, V2 synthetizer for sound and GLSL language for creating shaders. Everything is demonstratively created under Windows.

Graphics Intro 64kB Using OpenGL
Bobuľa, Matej ; Milet, Tomáš (referee) ; Matýšek, Michal (advisor)
This bachelor thesis deals with the problem of creating an OpenGL Graphical Intro with size limited to 64kB. It describes different techniques and methods used to create such intro. These methods are: procedural generation of terrain, procedural generation of textures, lighting, animation and particle systems. It also deals with size-reduction methods such as compiler configuration and file compression. The result of the intro is a stroll in the night on a volcanic island. Created graphics intro in its size does not exceed the given limit of 64kB.

Vertex/Pixel Shaders in Realtime Rendering
Ligmajer, Jiří ; Havel, Jiří (referee) ; Švub, Miroslav (advisor)
My bachelor's thesis is about vertex and pixel shaders. It is engaged in evolution, funcionality and usage of shaders in realtime graphics. This bachelor's thesis also includes tutorials, that are describing theory and implementation of three realtime rendering techniques, which were chosen by me. Results of my realtime techniques are evaluated at the end of my book.
