Interactive web applications supporting education of 3D graphics
Priščák, Jaroslav ; Mokrý, Ondřej (referee) ; Rajmic, Pavel (advisor)
The use of interactive web applications has the potential to significantly improve the teaching of 3D computer graphics. By taking advantage of the convenience and accessibility of the web, these applications can provide students with more engaging and interactive learning. This thesis explores the development of such applications to help understand the fundamentals required for calculations such as normal vectors and tangent planes. Further, the thesis describes Phong's illumination model, the environmental and material parameters that affect the resulting light reflection. It then describes the different shading models such as flat, Gouraud and Phong shading models, describing the various advantages and disadvantages, the differences in computational complexity in determining the color of a fragment and individual pixels. It also explains the code on which these applets are built.

Logistic system animation for production facilities
Mařata, Michal ; Hromková, Ivana (referee) ; Simeonov, Simeon (advisor)
The topic of this thesis is Logistic Systém Animation for Production Facilities. Animation planning of production gets posibility of more atractive, faster understanding of timing production line. The result of the thesis is classic program for Windows, written in C#. For better functionality of 3D visualization is addedd HelixToolkit library. The other result is web application written with JavaScript library Three.js. In Web Application is enabled to load 3D model of own factory (*.ifc file), loading other 3D models, changing their position and saving changes to the database (MS Excel, MS Access). During the animation is enabled to make changes (as speed, skipping steps).

Interactive web applications supporting education of 3D graphics
Morávek, Jan ; Mokrý, Ondřej (referee) ; Rajmic, Pavel (advisor)
This diploma thesis is focused on computer 3D graphics and the implementation of educational applications in JavaScript language. Discussed topics of computer graphics include object transformations, Bezier patches and the role of the camera in the scene. The thesis describes the basic theory of these areas and educational applications. The thesis also includes the detailed description of the features and the implementation of the created applications. In the end of the thesis possible extensions are discussed.

Detection and Recognition of Gun in a Scene
Stuchlík, David ; Goldmann, Tomáš (referee) ; Drahanský, Martin (advisor)
The aim of the diploma thesis is to design an algorithm for detection and recognition of the type of gun in the image. Firstly, the existing methods and techniques for detecting the various objects are briefly introduced in the text of the thesis however, the methods are primarily focused on guns. Next, the basics of neural networks are briefly outlined, followed by an overview of the most common detectors for deep neural networks. The second half of the thesis is devoted to the implementation of an application for generating images based on a 3D model of a gun, the creation of a data file and learning of a neural network. Finally, the results obtained, which clearly indicate that in order to cover a huge variation of real weapons, is necessary to generate a large amount of training data based on many different 3D models, are briefly summarized in the conclusion of the thesis.

Virtual Tour in VR
Pelánek, Lukáš ; Matýšek, Michal (referee) ; Herout, Adam (advisor)
This thesis deals with the making of virtual tours in the virtual reality. It deals with panoramic photographs and their use in creating virtual tours. In this thesis, two applications were designed and implemented. The first one as a web editor for creating and the other as a mobile application for viewing virtual tours. The created solution provides a comprehensive tool for working with virtual tours.

Polygonal Mesh Segmentation
Švancár, Matúš ; Kodym, Oldřich (referee) ; Španěl, Michal (advisor)
This bachelor thesis analyzes and approaches the issue of segmentation of polygonal models. It presents a design of an interactive method inspired by the method described in the Interactive Mesh Segmentation Based on Feature Preserving Harmonic Field. The method uses graph-cut and is implemented as a web application. The application supports .obj and .stl file formats, allows the user to load a model, draw sketches representing foreground and background on the surface of the model, and to start segmentation. Once completed, the user can download the resulting models or continue segmenting with one of them.

Atmospheric Efects in WebGL
Brydl, Jaroslav ; Lysek, Tomáš (referee) ; Starka, Tomáš (advisor)
This thesis deals with the simulation and rendering of atmospheric effects in WebGL using Three.js application interface. The principles of functioning and implementation of the effects of altering day and night, clouds, snow, rain and shadows are described. Effects are mostly implemented with GLSL shaders that allow easy use across different platforms.

3D Indoor Localization
Zvěřina, Jiří ; Polčák, Libor (referee) ; Veselý, Vladimír (advisor)
This thesis is about designing and creating 3D visualisation of interior localization using Sewio system. Visualisation is presented as web application with WebGL technology. WebGL deployment is simplified with Three.js library. For future scalability of the application, I deal with integration of Three.js into Model-View-Controller architecture. The last part of the thesis is about additional sensors and their use to make the localization more precise. There is a barometric senzor making vertical localization possible and inertial sensors useful for determining rotation of localized devices.

Interactive 3D graphics with WebGL
MÁČE, Lukáš
The aim of this bachelor thesis is to prepare options for creating and displaying interactive 3D graphics by using JavaScript environment WebGL. In this work, I will describe the basic methods and techniques which can be used to create interactive 3D content using WebGL. One of the options, which this bachelor thesis will deal with, is creating 3D graphics through Javascript commands, simultaneously using Javascript 3D library Three.js. Second option, which will be described with is creating interactive 3D graphics without knowledge of programming languages. This option is represented by graphics tools like Bledner or Coppercube 3D, which enables creating interactive 3D graphics and export them to the WebGL. Both methods will be analyzed and compared with each other. The outcome of the work will be set of practical examples, created by both methods.
