Simulation models of human operator.
Boháč, Petr ; Horák, Karel (referee) ; Havlíková, Marie (advisor)
This paper deals with simulation models of the human operator controlling lateral position of simulated vehicle. I am comparing parameters and quality of the McRuer human driver model and the PID controller. Simulated system is single-track vehicle model. Simulated driver is tasked to pass a Moose test with this vehicle model. I am using the simulated annealing method to find optimal parameters of the driver model and then I visualize realized test in 2D and 3D visualization. In the end of this paper I compare simulations of the driver models and assess achieved results.

Toolbox for neuronal datasets
Malý, Lukáš ; Harabiš, Vratislav (referee) ; Lamoš, Martin (advisor)
The aim of this bachelor's thesis was to create toolbox for functional magnetic resonance (fMRI) and electroencefalography (EEG) data processing in MATLAB enviroment using SPM software package. The first part describes the physiological origin of these data at neuronal level, basics of magnetic resonance imaging, principles of fMRI experiment, preprocessing and processing of fMRI data, their interpretation, then function and principles of EEG are described and at the end is simultaneous EEG-fMRI described. In the second part of the thesis features of each tool from Neural Data Toolbox (NDTb) are described.

Simple 3D Printer Simulator
Čillo, Vladimír ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
This thesis deals with design and implementation of 3D printer simulator in C++ using Qt. The simulator assumes a printer based on widely used method of 3D print - Fused Deposition Modeling. An input of simulator is a 3D model in STL file format. For the 3D model simulator provides an estimate of the total print time. Simulation also includes visualization of 3D print. The result is a cross-plaform program tested under Linux and Windows. Functionality of simulator has been tested by several experiments.

Design of an application for the visualization of geographic data documenting the development of defunct landscapes
Nekola, Lukáš ; Čábelka, Miroslav (advisor) ; Laštovička, Josef (referee)
This thesis deals with the design and subsequent creation of a 3D map application for visualization of geographic data documenting the development of the landscape in the cadastral area of Holešice. The added value is the creation of different variants of spatial SQL queries for the representation of changes in elevation and land use in the form of polygons. In the first part, the available technologies for the creation of the application are properly described together with the basic algorithms enabling the creation of polygons. The practical part starts with the preparation of a dataset of points created by data fusion representing the height division, which was stored with other data in a spatial database. This is followed by the creation of the application itself based on the proposed client-server architecture. The principle is to store the output of one of the queries in the form of a materialized view. Map service based on the query is created in GeoServer technology and displayed in the CesiumJS library. The specific choice of the output and the selection of the query variant depends on the submission of the form by the user. Key words: spatial database, 3D visualization, map application, defunct landscapes, Most region, web

3D vizualiazace a deep learning v mapách Stabilního katastru Čech
BLÁHA, Milan
This bachelor's thesis entitled "3D Visualization and Deep Learning in Maps of the Stable Cadastre of Bohemia" is devoted to several goals. The first one is to get acquainted with a stable cadastral map and deep learning. These terms are characterised and their meaning and other requisites are explained. Another aim of this thesis is to present the overall description of the monitored area and to cover its fundamental characteristics, historical development, physical-geographical aspects, population, settlements and a selected municipality. It also introduces the workflow of completing the practical part, which deals with the 2D and 3D visualizations of selected parts of the village of Nová Ves by Klikov, the Czech Republic. These visualisations are created on the basis of the original maps of the stable cadastre from 1827, and are made in ArcGIS Pro. Furthermore, the practical part of this thesis indicates possible practical use of these visualizations, maps of stable cadastre and deep learning.

3D data representation and visualization of complex features of traffic infrastructure
Hřebec, Tomáš ; Brůha, Lukáš (advisor) ; Laštovička, Josef (referee)
7 Abstract This bachelor thesis designs and implements the process of creating and visualizing of 3D models of complex elements of road infrastructure with focus on level crossing. The theoretical part outlines the principles of modeling, methods of collecting spatial data using the Structure from Motion method and aerial images. This thesis also introduces the basics of Blender software, which the model is created in, and how ArcGIS Pro software, in which the final models are visualized, works with 3D data. Model of a bridge is created by an add-on for Blender. This work describes how the add-on was created, how it works and how to control it. In the end, there is described how to visualize the models. Keywords: Spatial data structures, 3D GIS, 3D visualization, traffic infrastructure

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).

Music Visualization in 3D
Vincena, Petr ; Rittig, Tobias (advisor) ; Hajič, Jan (referee)
Music is an important part of our lives and music emotion recognition is an important field of study with many applications. In this work, we focus on music features extraction and subsequent creation of music emotion recognition system. We extend the work of Hun at al. [2009] in order to create a feed-forward neural network model that predicts emotions from music which we can use in visualization. We confirm the results and discuss their impact. We also provide a C# project to extract several features from music that can be used in Unity together with the demonstration scene that visualize these features. 1

Visualization of insect morphological structures using x-ray microtomography and other modern 3D techniques
Rosová, Kateřina ; Prokop, Jakub (advisor) ; Janšta, Petr (referee)
In my bachelor thesis I describe techniques currently used for 3D visualization of morphological structures of insects. Since X-ray microtomography is currently the most attractive option for visualizing internal insect structures, more space is dedicated to its description, but the work includes more innovative techniques. Traditional techniques used in the past decades are not neglected, since they do not lose their importance in the competition of new methods. In the first part the individual methods are presented in terms of their simplified functional mechanisms and the basic steps of creation of 3D reconstructions are described. Techniques are further compared in the text in terms of their usability on different types and sizes of samples, according to the desired final resolution of the visualization, the time required to complete the observation and final visualization and in terms of invasiveness of the techniques. The last chapter summarizes the possibilities of using these innovative methods in entomology based on available studies. Keywords: Insecta, morphology, 3D visualization, SEM, CLSM, MRI, Micro-CT
