Virtual Blacksmith
Halamová, Mária ; Vlnas, Michal (referee) ; Milet, Tomáš (advisor)
This thesis deals with creation of an application for demonstration of smithing for virtual reality platforms. The purpose of the application is to present historical smithing craft with the help of modern technologies from the first person's view. The thesis researches realistic simulation methods used in smithing techniques and an appropriate way of visualising a metal object. The application implements a 3D simulation of heating and deformation of forging materials using user-controlled forging tools in virtual reality. Partial heating of the metal is visualized by procedural material. The user experience is enhanced by added audio and haptic feedback. The final application is created in Unity framework and is developed for Oculus Rift virtual reality set.

Visualization of flight data to passengers
Alfery, Vladimír ; Dittrich, Petr (referee) ; Chudý, Peter (advisor)
The goal of the thesis is to enable passengers to see the actual flight information, which the pilot sees from the cockpit. This information is viewable on electronic device connected to the aircraft internal wireless network. Web application which uses CesiumJS library to view terrain is used in order to ensure compatibility with the most nowadays devices with operating system Windows, OS X, iOS and Android.

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.

Use of Head-mounted displays in risk management for machine tools
Jelínek, Martin ; Kotek, Luboš (referee) ; Tůma, Zdeněk (advisor)
This diploma thesis deals with the design and technical possibilities of VR headsets and their application in mechanical engineering, specifically in the field of risk management in machine tools, using experience from other areas and history. The practical part of the thesis comprises a risk analysis carried out on a single selected machine (vertical machining center) by means of checklists and virtual technologies. The risk analysis techniques used are subsequently compared and evaluated. The results are then assessed and a proposal for the use of virtual reality in practice is put forward.

Model visualization in virtual reality
Lukačovič, Samuel ; Lacko, Branislav (referee) ; Hůlka, Tomáš (advisor)
This thesis is dedicated to a term called virtual reality, its history, applications and possible technological adaptations. Subsequently the focus is going to shift towards a type of software called game engine. The function, historical development and various kinds of game engines are going to be closely described. Practical part of the thesis is going to be focused on making of training simulation in virtual reality. During development the unique features of the chosen game engine, thanks to which this game engine is suitable for creating such applications, are going to be used.

Use of Virtual Reality Technology for Monitoring and Visualization of Selected Operational Charakteristics of Machines and Their Analysis
Augste, Jan ; Mostýn, Vladimír (referee) ; Szabó, István (referee) ; Knoflíček, Radek (advisor)
This dissertation deals with the study of the use of virtual technologies for an analysis of operating characteristics of a machine. Operating characteristics of a machine are parameters that determine the usability of the machine to accomplish a certain task in addition to the specified time and under the certain conditions. These include parameters that can be changed based on customer requirements, for example, the table size and the highest spindle speed to the parameters influenced from the start of the machine design such as positioning accuracy, acceleration value in the axes or consumption. The first part sets out general requirements for visualization of information and these are subsequently verified experimentally in the chapter devoted to the time visualization protocol. This thesis presents the original experiments to determine the basic requirements for visualization of a measured quantity, in this case the feed rate. By verifying usability when displaying these properties on the underlying data showing machine position change, the four basic requirements for visual data processing using immerse virtual reality are validated. A deeper insight into the work with data will enable to analyse more complicated relations within a longer period, greater transparency and clearer outputs of analysis.

File Manager in 3D
Martinák, Ondřej ; Sumec, Stanislav (referee) ; Beran, Vítězslav (advisor)
This thesis concentrates on a design of 3D user interface for interaction with a file system. It presents a short description of 3D user interfaces and techniques used for their design and implementation. It also presents a brief description of libraries which might be used for development of virtual reality applications and a description od device which was used for graphical output and an acquisition of informations about user's head movements.

Optimalization for Stereoscopic Visualization
Zelníček, Leoš ; Seeman, Michal (referee) ; Beran, Vítězslav (advisor)
This work envolves basic options of human visual sense, describes matter of depth perception. We analyze binocular vision of humans, its limits, which must be considered, and followed when trying to project stereoscopic pictures. Then, we mention the most common methods of stereoscopic projection, reader is made acquainted with their options, advantages, and difficulties. The biggest part of this work is dedicated to the optimalizations themselves. They are focused on the most effective rendering of 3D scenes using stereoscopic technology. The effort is to make the best stereoscopic engine as possible and to inspect and improve displayed scene, so that the stereoeffect would be the best. Trivisio ARvision-3D HMD was used for testing purposes.

Mathematical modeling of mechanical systems of vehicles
Zháňal, Lubor ; Svída, David (referee) ; Porteš, Petr (advisor)
This thesis deals with design and implementation of the computing system, which would allow interactive simulation of kinematics and dynamics of vehicle mechanical systems or general mechanisms with the help of modern computer technology. In the thesis is described a basic working principle, optimization of numerical simulation parameters, as well as the implementation itself in the form of functional application and its key parts. Described are also possibilities for the use of virtual reality devices in conjunction with visualization of simulation process. Final comparative tests have confirmed the functionality and high performance of the created system.
