Generating Procedural Terrains
Petlan, Michael ; Bartoň, Radek (referee) ; Přibyl, Jaroslav (advisor)
This thesis deals with algorithms of stochastic generating of height maps. The thesis describes the basic theoretical knowledge and extends it by usage of L-systems for generating a network of rivers. There has been implemented a library of the height map generating algorithms and a demo application within the thesis.

Graphics Intro 64kB Using OpenGL
Juránková, Markéta ; Havel, Jiří (referee) ; Herout, Adam (advisor)
The aim of the master's thesis is to create a graphic intro with the limited size of 64kB. Brief history of a demoscene and the graphics library OpenGL is introduced in the following text. The main part of the work is a description of minimal graphics techniques used in a creative process and their further application in the final programme.

Level of Detail for Race Track Rendering
Mohelník, Petr ; Milet, Tomáš (referee) ; Polok, Lukáš (advisor)
This work describes efficient race track rendering using OpenGL. It uses height map for terrain representation. The race track is rendered as polygonal model instanced on a curve using level of detail. An algorithm is proposed for using level of detail in real time even on mobile devices. Among described algorithms are dart throwing, Catmull-Rom spline, edge collapse simplification, view frustum culling. Part of this work is an application demonstrating the designed algorithm.

A Set of Web Tools for Visualization Geo-Location System Performance
Hodoval, Pavel ; Pavelková, Alena (referee) ; Brejcha, Jan (advisor)
Aim of this thesis is to create a set of web tools and web user interface to present the results of geo-location system. Thesis contains introduction to theory of data visualization in cartography and basic image processing algorithms. Also there is a research of existingsolutions and tools as well as available web technologies. As a result, a library for geographic data processing and visualization was implemented and its results are shown as web map presenting geographical and statistical data. Quality of the implementation was verified and tested by user test and automated machine test with mostly positive results.

Interactive 3D Terrain Editor
Hulva, Jiří ; Vanek, Juraj (referee) ; Přibyl, Jaroslav (advisor)
The purpose of this work is to design and implement an interactive 3D terrain editor. The application should be able to create three-dimensional model of a terrain from input data, display it and allow free movement in displayed scene. Users should be provided with tools for editing heightmaps and surface textures. There should be option to load models of objects, like buildings or vegetation and place them on chosen locations.

Realtime Weather in a Landscape Visualisation
Vlček, Adam ; Jošth, Radovan (referee) ; Seeman, Michal (advisor)
Thanks to the increasing computation power the complexity and dynamism of virtual reality is continuously improving. This work aims to examine influences of weather in a landscape and the means to simulate and dynamically visualize them in real time on the current personal computer hardware. The main goal is to find quick well looking approximations rather than a complex physically correct simulation. The work covers using modern programmable GPU not only for visualization but also as a powerful simulation instrument. The main topic is water movement in the terrain and its effects on it like erosion, snow melting and moisture impact on vegetation. This requires dynamic terrain texturing and algorithms supporting fast geometry and normals updates.

Adaptive Level of Detail for Planet Rendering
Moravec, Matěj ; Milet, Tomáš (referee) ; Matýšek, Michal (advisor)
This bachelor thesis is focused on real time planet rendering with adaptive level of terain detail in Unity engine. Chunked LOD algorithm is modified and used for adaptive change of level of detail. Intancing is used for efective data rendering. Graphic card is used for creating planet geometry with heightmaps and there is also tessellation used for gradual morfing of level change of detail.

Interactive 3D Terrain Editor
Synáček, Jan ; Beran, Vítězslav (referee) ; Přibyl, Jaroslav (advisor)
The subject matter of this work is a concept of an interactive 3D terrain editor. Its basic functionality, graphical user interface and possible extensions are defined. There are a lot of existing terrain editing tools, therefore presentation of some existing systems capable of editing and generating computer terrain is also included. The editor is implemented and it is capable of performing simple editing, such as raising, lowering or levelling the terrain. Graphical user interface is also a part of the implementation. The editor allows inserting 3D models into the scene so it was easier to represent some objects displayed only in the texture in 3D space. Models can be edited using some simple transformations. Performance tests are undertaken and possibilities of extending the program discussed.

Realistic Visualization of Environment in Computer Games
Jozefov, David ; Bartoň, Radek (referee) ; Mikolov, Tomáš (advisor)
This bachelor thesis shows the basics of landscape rendering in computer games. It explains fundamental principles of computer graphics creation and implementation of the three parts of the landscape - terrain, water surface and the sky. In more detail it describes Brute force and ROAM algorithms for terrain rendering and compares the achieved results of the both of them.
