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.

Graphics Intro 64kB Using Ray Tracing
Krupa, Martin ; Navrátil, Jan (referee) ; Herout, Adam (advisor)
The object of my bachelor's thesis was to get acquainted with phenomenon of graphics intro with limmited size, to study actual display techniques, which are using real-time ray tracing and make own graphics intro by using these techniques and executable of this intro is limmited to 64kB. The work also briefly introduces history of making graphics intros and reasons for their creation. It contains description of techniques used to create intro and comparation of them. This work also describes own implementation of aplication and its results. Finally there is evaluation of thesis and ways of improvements.

3D Graphics in Web Browser
Kuželová, Ludmila ; Kršek, Přemysl (referee) ; Španěl, Michal (advisor)
The thesis deals with the creation of a three-dimensional virtual view with the use of the new WebGL standard in combination with O3D javascript framework. The result is freely available web application which generates a virtual tour of sent series of photographs. Afterwards, the photographs are processed by the server, which on the basis of found corresponding points creates 3D scene. The application is based on a freeware application Bundler [40] which is used for identifying 3D points in uploaded photographs and related cameras (the places from which the photographs were taken). Bundler outputs are processed by Jetty web server with the use of Java script. At this point, all data required for the creation of a view are gathered. The display of the final result is then realized via HTML5, CSS, WebGL and Javascript using O3D.

Searching for Similar 3D Models
Šťáva, Zdeněk ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This paper deals with searching similar 3D models in a database containing up to thousands of models. It focuses in particular on the comparison of existing descriptors used to describe 3D models and the subsequent evaluation of similarity between models. In particular, the descriptors Rotation Invariant Spherical Harmonics and 3D Zernike Descriptor are compared. It also describes the use of libraries to extract these descriptors and to design of various experiments with these libraries over several object databases. It examines the effect of scale, translation, deformation and rotation of different 3D models on the resulting descriptor and the overall accuracy of both selected methods. These results compare.

Karel 3D - Application for Teaching of Programming
Čoupek, Vojtěch ; Regéciová, Dominika (referee) ; Křivka, Zbyněk (advisor)
The work provides a survey of the tools available for the teachers of Informatics who teach students the basics of programming. The main aim is to create the implementation of Karel pedagogic language inspired by the work of Andrej Blaho and his colleagues for MS-DOS platform. The new web application is introduced that expands the functionality of the original language with variables and includes the up-to-date elements of the user interface, such as block programming, highlighting the language syntax, syntax checking and 3D graphics. The application also provides a set of basic examples for teachers and allows them to create their own tasks.

Endless Cave
Pospíšil, Petr ; Pečiva, Jan (referee) ; Milet, Tomáš (advisor)
The goal of this thesis is to implement an application showing an endless cave. The basis of this cave is simplex noise method. On the noise produced by this function is afterwards applied thresholding. Produced grid of points is used like input for marching tetrahedrons algorithm. This algorithm converts volumetric data to boundary representation. Phong reflection model and Bump mapping were used in the application, too, in order to improve the visual quality. The application is based on OpenGL library. The first part of the technical report contains theoretical description of mentioned methods, the second part contains description of implementation.
