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.

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.

Large Scene Rendering
Langer, Lukáš ; Tóth, Michal (referee) ; Starka, Tomáš (advisor)
Work discusses rendering of complex scenes and terrain. It's main task is to show the extensive scenery terrain that normally do not fit in the graphic card memory. It introduce the theory of terrain rendering including terrain level of detail algoritms. The paper presents the design and implementation of application that implements dynamic streaming of complex terrain.

Graphics Demo Employing Procedural Textures
Drevický, Dušan ; Matýšek, Michal (referee) ; Polok, Lukáš (advisor)
This thesis deals with the design and implementation of a size-limited 64 kB graphics demo. Procedural generation is used for the definition of structure and appearance of realistic natural terrain. The terrain is described by a heightmap based on noise functions described in this work. Rendering utilizes the ray marching method and is done in real time. All parts of the implementation described in this work were created exclusively within the fragment shader of the GPU.

Landscape Reconstruction from Tourist Map
Tuška, David ; Šilhavá, Jana (referee) ; Španěl, Michal (advisor)
This work deals with problems of digitizing tourist map. The goal of this project is proposal and implementation computer program, which can be able to create heightmap from tourist map. Heightmap is a raster image used to store values of surface elevation. For example heightmaps are widely used in terrain rendering software and modern video games.

Navigation using a turistic map
Mihál, Jakub ; Babinec, Tomáš (referee) ; Horák, Karel (advisor)
The master’s thesis deals with the design and realization of a program that is able to find the shortest route in the tourist map between selected points. The user can select the type of hiking trail. Application also generates terrain heightmap from contour lines and path elevation profile.
