Clouds and Hills Generation Using Fractal Geometry
Tůma, Petr ; Zuzaňák, Jiří (referee) ; Venera, Jiří (advisor)
This work is concerned with generation of landscape objects using fractal geometry. In this work is explained what the fractal is and terms associated with them. The other parts describe basic theoretical ideas and implementation of these algorithms. The Capital theme is generation of models clouds and hills in values of input parameters, their presentation and date media saved there. The project includes my algorithm extension for hills generation of course. At the conclusion of this work are summarized tendencies of next development and my results.

Parametric city modelling
Demková, Michaela ; Kratochvíl, Richard (referee) ; Volařík, Tomáš (advisor)
This thesis deals with the creation of a parametric 3D city model based on available spatial data.. The content is divided into two parts. The theoretical part describes the current state of 3D modeling and the second part describes the process of creating the final model and its conversion to CityGML.

Procedural Generation of City Topology
Zvěřina, Lukáš ; Navrátil, Jan (referee) ; Láník, Aleš (advisor)
This bachelor's thesis is about problematique of procedural modeling. It especially tatgets procedural generation of city topology, using fractal geometry, rewriting gramatics using L-systems, OpenGL library for displaying scene and detailed description of approaches in texturing, lighting and other graphics effects.

Wang Tiles for Frequency-Based Synthesis of Ocean Surfaces
Vámošová, Mária ; Wilkie, Alexander (advisor) ; Krajíček, Václav (referee)
Frequency-based ocean synthesis is a class of methods for generating ocean waves in deep water using physically based ocean spectra provided by oceanographic research. The output of these methods is a heightfield which is periodic and can be used to tile a larger area. However, when using a larger number of tiles, a repetition pattern becomes apparent. Wang tiling is a method of tiling the plane non- periodically by using only a small set of input tiles with given constraints. The aim of this thesis is to create a set of Wang Tiles, each of which represents an ocean heightfield synthesised by a frequency- based method, so one can create large ocean scenes without apparent periodicity in the tiling pattern.

Generalization of LOD2 building models using the aggregation method
Měchurová, Kristýna ; Brůha, Lukáš (advisor) ; Pokorný, Tomáš (referee)
Generalization of LOD2 building models using the aggregation method Abstract The thesis proposes and implements a method of 3D building models aggregation. The procedure achieves global optima by the means of mathematic optimization. Buildings are aggregated according to similarity characteristics typical for LOD2, e. g. roof type. Aggregation process is driven by minimalization of volume changes and of the aggregate count. The optimization problem was implemented as a Python script with optional parameters to meet custom demands of a wide range of users. Input data models of buildings are created by the method of procedural modelling. Its outcome is further restructured into form of continuous blocks. Finally, the visualization procedure is designed and implemented to illustrate the results of optimized aggregation of 3D building models. Keywords: 3D GIS, generalization, aggregation, mathematical optimization, procedural modelling
