Advanced Rendering in OpenSceneGraph Library
Ondruška, Jiří ; Přibyl, Jaroslav (referee) ; Švub, Miroslav (advisor)
This bachelor's thesis presents OpenSceneGraph library and its use with shaders written in OpenGL Shading Language. First of all it presents the basics of GLSL. Next chapter introduces the basics of OpenSceneGraph library. Following chapters are about different shaders. First is vertex displacement mapping, followed by cartooning and the last one is water surface.

Human Face Mimics
Melicher, Alexander ; Chudý, Peter (referee) ; Jošth, Radovan (advisor)
Bachelor's thesis is concerned with the demonstration of human facial gestures, which has been frequently used in developement of computer games and animated movies. The main brief of work was to create 3D model in open-source graphic software Blender. Subsequently, an application for loading of the created model and displaying the model on the screen was developed using a rendering algorithm. The application allow user to create common facial gestures by simple keyboard control. A technigue for moving the vertices was applied to some delimited areas on the face.

Programmable Shaders in OpenSceneGraph
Czompál, Zsolt ; Španěl, Michal (referee) ; Švub, Miroslav (advisor)
Graphic processors, that are used nowadays, have programmable units called shaders. By programming these units we can achieve better results in graphical applications, than by running the effect or the program on the processor. There are different programming languages for programming these units. In this thesis I have chosen the language GLSL with OpenSceneGraph API. The main point of the following capitols is to demonstrate how do shaders work with OpenSceneGraph, and the implementation of common graphic effects.

Physical Simulation in Graphics Scene
Javorka, Marián ; Herout, Adam (referee) ; Pečiva, Jan (advisor)
This master's thesis deals with physical simulation of cars. Program is implemented in C++ using OpenSceneGraph and Bullet libraries, which are shortly introduced. The application is implemented as simple racing game for one or two players. Using a simple menu, the user can select a car and the weather, which dramatically affects the handling characteristics of vehicles. Setting weather to random is one of the options leading to a dynamic weather changes during the game. The application takes into account collisions among cars and collisions with the terrain and bars on a racing circuit.

Advanced Editor of 3D Scene
Bišof, Martin ; Žák, Pavel (referee) ; Přibyl, Jaroslav (advisor)
This work describes important periods of making application on editing 3D scene. It concerns a program which makes possible visualization of objects and simulation graphic scene. The introduction of this document is dedicated to theorical analysis, which is oriented on objects presentation in computer graphic with detailed orientation on Boundary Representation. The following chapter is about transformations and manipulators. Design part introduces basic problems and apprises with exercise solutions on general level. In the part of the implementation, we find detailed description of actual solution for particular phase of proposal. It states description of advanced camera system and transformation of objects by the help of graphic manipulators. The next chapter discuss implement effects, modifications and solution for graphical user interface.

Comparison of Open Source Rendering Libraries
Záleta, Martin ; Herout, Adam (referee) ; Havel, Jiří (advisor)
The main purpose of this paper is to provide a detailed analysis of some of the major available open source rendering libraries with the emphasis on their notable characteristics, and an in-depth comparison among them with regards to their possible practical use. Specifically, the selected rendering libraries in this paper are the following - OpenSceneGraph, Ogre 3D, Irrlicht Engine, Crystal Space and OpenSG, but a sidenote is given to some of the others as well. Last but not least, self-made examples of their usage are also included, and are meant to demonstrate some of the mentioned characteristics and principles of the analysed libraries.

Algorithms of Level of Detail in OpenSceneGraph
Hupka, Dušan ; Milet, Tomáš (referee) ; Pečiva, Jan (advisor)
Present graphic requires a lot of optimizations of rendering techniques and mathematical calculations. It is caused by increased requirements of scene's visualization. One of scene's optimizing techniques is the Level of detail. This thesis is focused on methods used by LOD in OpenSceneGraph and OpenGL library. Next it will be described how to choose the right level of detail in a scene. Later it will be explained how to simplify 3D models. These techniques will be implemented in converting tool and demonstrating application. Methods for simplify 3D models will be tested for their speed and quality.

Tooth Detection on Jaw 3D Computer Polygonal Model
Filip, Jan ; Šiler, Ondřej (referee) ; Kršek, Přemysl (advisor)
Aim of this bachelor thesis is a proposal and an implementation of a tool for the tooth detection on a 3D computer polygonal jaw model, which will allow to a user to obtain the shape of teeth on the jaw. This tool should to help in the stomatology. In the event of any inaccurary in the detection it will be possible to change certain parameters and methods, by which will be possible to influence the accuracy of detection. Program will import models in the STL format and subsequently will allow to the user to see the result of the detection in a browser. Teeth detection models will be possible to export single or together, in the STL format. The implementation language will be C++, compiler GNU C in distribution MinGW, toolkit to work with the 3D model will MDSTk and primarily its part VectorEntity. For imaging of thr 3D scene will be used OpenSceneGraph toolkit. Application will be developed primarily for MS Windows operating system but thanks to using GNU tools should be portable at the level of source codes to anothers operating systems.
