This thesis is focused on interaction with object in 3D environment. For detection of user is used the Microsoft Kinect device. Interaction is based on touchless control which is inspirated by reality.  Behaviour of designed solution is researched in experiments and some application is created for demonstration of functionality.

The main topic of this thesis is to create a simulator for educational purposes, which is able to simulate the traffic situations and to control the compliance of traffic regulations. Modern game engine Unity 3D and development of simulator in C # for this engine are introduced within this thesis. Creating a simulator or computer game in general, imposes multiple requirements in different disciplines, and therefore, this work deals with themes such as the creation of 3D models, work with audio content, design of virtual city model, etc.

Purpose of this thesis is to introduce reader to 3D parametric construction tools and their application with dynamic geometry. Project introduces basic concepts of parametric construction in computer geometry, summary of the state of the art, description of selected parametric geometry software, evaluation of its features and design of 3D parametric geometry library for use in computer graphics followed by implementation of said library and user interface application for evaluation.

This work deals with description and design of application for generating 3D building models from floor plans and their publication on the Internet. First chapter describes methods used for floor plans creation. Next part describes how are foor plans transformed into three-dimensional model. Following chapters describes implementation details concerning application used for creation of building floor plan and three-dimensional model generation. Work also covers implementation of web based application for viewing models in web browser. Final chapters sums up results and limitations of described solution. There are also discussed possible extensions of current project.

This master's thesis describes the visualization of program flow of executable files on Microsoft Windows platform. In theoretical part it describes the PE EXE file format and instruction format. In following chapters there are described current methods of malware analysis, especially the analysis of program flow. Then there are introduced current malware visualization methods and tools for 3D data visualization. The main objective is design and implementation of 3D visualization of jumps in executable files. The result is the visualization tool, which helps to identify different samples of malware from the normal code.

This text was written as part of a master's thesis. It describes development of an automatic generator of 3D models for Blender. After a brief introduction to the Blender application some of existing scripts for 3D model creation (tested as part of theoretical research) are presented. After an analysis of features required from an automatic generator various types of swords were chosen as the suitable class of objects for the automatic creation. Next part of this thesis presents basic terms in this field, namely the nomenclature of the swords and other related weapons. Their most important properties are listed and explained. The chapter also provides a simplified abstract of the sword typology. Following chapters describe main ideas of creating the model, explain principles and mathematics behind used algorithms and procedures and provide information about realization of the GUI as well as testing and optimisation. As the text explains these issues, sugestions about possible future enhancements are made. Document is concluded with an evaluation of all achievements and argues impact of this work on its field.

The matter of this thesis is to find the influence of the diameter of the nozzle on the 3D printer´s print quality. The first part briefly characterizes the Rapid Prototyping technology and describes the RepRap project. The second part describes the construction of the experimental FMD 3D printer. The following section deals with technical printing parametres and their influence on the printed product. The experimental part of the thesis is focused on the impact of the discharge nozzle diameter on the mechanical properties, surface quality and shape accuracy of the final product and on the following recommendations of operational parametres.

An experimental methodology for wear assessment of extracted polyethylene hip implants was designed in this diploma thesis. Methodology uses optical 3D scanner and optical profilometer for analysis of wear. Designed methodology for wear analysis was validated by gravimetric method. The results of validation were in good agreement with the increase of wear rate. Validation results show that the methodology is not suited for wear assessment of metal and ceramic implants which have small wear rates. On the other hand the methodology is more than useful for wear assessment of polyethylene implants. Designed methodology for wear assessment was applied on the set of thirteen extracted polyethylene hip implants. Results of the wear analysis were wear volumes and linear wear noted in the wear maps. Roughness of the surface was measured on explanted cups and results were noted in the roughness map. On articulating surface of the cups different areas were observed for measured roughness. Those areas were described as area with machining marks from manufacturing process, polished area from combination of abrasive and adhesive wear, polished area from micro-contact fatigue and area including plastic deformation.

The result of this thesis is to create an overview of available 3D printing technologies, design a 3D FDM printer, create an instructional manual on the assembling and create a business model of a 3D printing company.

The aim of this thesis was to produce a prototype casting of aluminum alloy with usage of reverse engineering technology. In a production process surface quality and dimensional accuracy was optimized. 3D scanning, FDM technology, ABSplus surface finishing possibilities and investment casting technology is introduced in theoretical part of this thesis. Practical part of the thesis includes description of original parts, their 3D scanning, usage of RE and RP, production of new castings and evaluation of their dimensional accuracy and surface roughness.
