3D Video Browser
Míchal, Vít ; Štancl, Vít (referee) ; Beran, Vítězslav (advisor)
The aim of this project is to design and create application for the visualization of interconnected video data. Visualization takes place in 3D space and seeks to exploit its advantages (such as depth perception). This document contains survey to different categories of spatial user interfaces. In addition, includes three possible designs of user interfaces and control. Implementation details and made usability tests are also described. Application is implemented in C++ using Open Inventor. The document includes evaluation of the results and made tests.

Rendering Complex 3D Scenes
Mrkvička, Tomáš ; Kršek, Přemysl (referee) ; Herout, Adam (advisor)
This thesis deals with representation of large and complex 3D scenes which are usually used by modern computer games. Main aim is design and implementation of data driven rendering system. Proper rendering is directed (driven) by scene description. This description is also designed with respect to scene creators whose typically do not have deep knowledge of programming languages in contrast to game programming developers. First part is focused on design of efficient scene description and its possible applications at scene rendering. Second part is focused on proper system implementation. Finally, consequently important system optimizations are mentioned too.

Development and Implementation of Energy Savings and Energy Management Methodology in an Industrial Enterprise
Dudarev, Ivan ; Demeč, Peter (referee) ; Suchánek, Rostislav (referee) ; Blecha, Petr (advisor)
V současné době se problematika energetických úspor dostává do popředí zájmu jak na úrovni jednotlivých podniků, tak i na úrovni celého státu. Často bývá příčinou sporů ve vědeckých kruzích i mezi odborníky z praxe. Lidstvo tradičně začalo využívat energii z minerálních přírodních zdrojů, které však ve srovnání s obnovitelnými zdroji energie mají omezení. Výzkum a implementace moderních technologií jsou ztíženy otázkou investic a časově omezeny. Proto se evropská strategie energetické bezpečnosti zaměřuje na energetickou účinnost, která je jedním z nejefektivnějších způsobů zlepšení bezpečnosti spotřeby energie. Velké společnosti a podniky jsou jedním z hlavních spotřebitelů energie. Proto je tato vědecká práce zaměřena na problematiku úspor energie a zlepšování energetické účinnosti podniku. Těžiště práce spočívá ve vytvoření a zavedení metodiky pro úsporu energie a managementu hospodaření s energií ve výrobním procesu automobilového podniku. Dále je pro účely této práce vytvořen a popsán způsob vizualizace spotřeby energie v prostředí virtuální reality

Verification of the State of the Real Production Line using Virtual Reality
Tůma, Zdeněk ; Hajduk, Mikuláš (referee) ; Mostýn, Vladimír (referee) ; Knoflíček, Radek (advisor)
The doctoral thesis focuses on the verification of state real work using virtual reality. Working with the theme dealt with more comprehensively, taking into account the sub-process of the production line design. From the assessment of the actual place where the future production line will be locate, through ergonomic, risk and other analysis. Furthermore, energy consumption of production line (electricity, air consumption, etc.) in real process. In analysing the readiness of virtual reality applications were selected for the following work augmented reality. The biggest advantage of augmented reality is the implementation of a virtual model and the opportunity to deal with the analysis in a real environment, which is particularly beneficial in the case of manufacturing companies. For the composition and optimization of the proposed solution was used a system approach. In the first phase of the solution was made analysis the current state of the work, which created requirements for the design of the new production line. This was followed by the preparation phase of construction in 3D, in this case, Autodesk Inventor. In this phase it was appeared to be advantageous to use the application of virtual reality, as in the design process leads to regular approval procedure of the experts team (management, design, quality, etc.), which puts on the readiness of the team high skills requirements. In this phase, the 3D design of the new production line was inserted into the support augmented reality application and outlined several opportunities to deal ergonomic and risk analysis. The proposed solution also follows the deployment in lean production area in the design phase, where it is possible to solve the analysis process using indirect methods of standard time (MOST). The result of the doctoral thesis is the extension options in designing and analysing production lines and machines in multidisciplinary teams. The proposed solution described in the thesis allows to simplification and reduce the overall time and costs of the overall process from design phase of production line to its commissioning.

Utilization of Virtual Reality Technology in Risk Analysis and Safety of Production Machines
Novotný, Tomáš ; Hajduk,, Mikuláš (referee) ; Krutiš, Vladimír (referee) ; Knoflíček, Radek (advisor)
The doctoral thesis introduces a study of possibilities for utilization of virtual reality technology in risk analysis and safety of production machines. The main goal of the thesis is to analyse and examine possible means of integrating visualization and interaction techniques of virtual reality into the risk identification process in the early stage of the production machine life cycle. The proposed work provides a methodological approach to the theoretical implementation of these techniques in the definition of dangerous areas of a machine, identification of sources of possible risks and verification of applied measures built-in in the machine structure. A system approach is used for forming and optimizing the introduced methodological procedures. The solution includes the design of the methodology for effective transfer of 3D design data into immersion virtual reality domain. This enables overcoming existing barriers in exploitation of virtual reality technologies in industrial applications. The next section introduces a procedure of implementation of real tools and equipment in immersion virtual reality domain, including an option for detection of collisions between the real tools and virtual objects. Experimental tests confirm its capability of practical utilization. The impact of the final practical contribution is shown by a decrease in the number of accidents during assembly work, due to its appropriate planning and thanks to training of the personnel on a virtual prototype, carried out already before the manufacturing of the actual machine. The result of the presented doctoral thesis contributes to further qualitative improvement of techniques and methods for preventive increase of safety and reliability of developed machines, particularly of machining centres, which will help increase their competitiveness. The properties of the designed procedures are documented and verified on real industrial cases.

Visualization of the results of vehicle dynamics simulations
Štefanec, Tomáš ; Kučera, Pavel (referee) ; Porteš, Petr (advisor)
The master thesis is focused on creation of a visualization environment that displays a movement of a vehicle. A connection of the virtual reality with Matlab/Simulink and its 3D Animation toolbox is realized. Basic parameters of the vehicle can be easily edited using application created in Matlab. Selected dynamic effects are rendered together with the movement of the vehicle. The visualization is managed by results of the simulation calculations or measurements.
