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.

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.

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.

A Tool for Sharing and Visualization of Skydiving Records
Madaj, Tomáš ; Kolář, Martin (referee) ; Herout, Adam (advisor)
Purpose of this work is to create a web application which would enable easiest possible 3D visualisation and sharing of uploaded GPS logs. It is intended mainly for aerosports. The application is built on the full-stack JavaScript platform Meteor.js, it features a web user interface and utilizes WebGL library three.js for 3D visualisations in browser. This form allows to achieve intended accessibility and simplicity of usage. The application is a valuable sports performance analysis tool. It brings accurate view of the actual trajectory in the sky where it's otherwise impossible due to the absence of a close visual reference point.

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).

Rendering Volumetric Data in Web Browser
Fisla, Jakub ; Zemčík, Pavel (referee) ; Španěl, Michal (advisor)
This thesis discusses rendering capabilities of web browsers of accelerated 3D scene rendering. It specifically deals with direct volumetric medical data visualization. It focuses on the usage of ray casting algorithm, its quality and its realistic rendering options. One of the goals was to create an application that demonstrates the ability to render three-dimensional volume data in a web browser using WebGL. The application is written in JavaSript and its 3D rendering core uses the Three.js library.

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.

3D Game Using WebGL - Inball
Jurčík, Lukáš ; Navrátil, Jan (referee) ; Szentandrási, István (advisor)
This bachelor thesis outlines the possibilities of making 3D applications in web-browsers, focusing on computer games. First, different methods of creating games inside web-browsers are briefly introduced. Next section contains a description of WebGL's frameworks and physics in games. The aim of this work was to design and implement a 3D browser game called Inball based on games like Neverball and Ballance. The application is based on WebGL technology using Three.js of frameworks encapsulating WebGL.

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.
