Fractals in Computer Graphics
Heiník, Jan ; Španěl, Michal (referee) ; Herout, Adam (advisor)
This Master's thesis deals with history of Fractal geometry and describes the fractal science development. In the begining there are essential Fractal science terms explained. Then description of fractal types and typical or most known examples of them are mentioned. Fractal knowledge application besides computer graphics area is discussed. Thesis informs about fractal geometry practical usage. Few present software packages or more programs which can be used for making fractal pictures are described in this work. Some of theirs capabilities are described. Thesis' practical part consists of slides, demonstrational program and poster. Electronical slides represents brief scheme usable for fractal geometry realm lectures. Program generates selected fractal types. Thesis results are projected on poster.

Realistic Landscape with Vegetation
Zelený, Jan ; Jošth, Radovan (referee) ; Hradiš, Michal (advisor)
There is enough rendering power to draw more than only simple indoor scenes today and it can produce very realistic images of landscape with vegetation. Moreover, there are new sophisticated methods for generating of such landscape and simulation of plants ecosystem. This text explains few algorithms for generating and methods for interactive rendering of landscape and vegetation.

Evolutionary Design of 3D Structures
Kovařík, Roman ; Sekanina, Lukáš (referee) ; Jaroš, Jiří (advisor)
This work deals with evolutionary design of 3D structures. The work brings the summary of the previous works in this area and brings autor's suggested solution of evolutionary design of 3D structures. This paper seeks to the ability of easy fitness function definition in the systems for evolutionary design of structures. The author tries to make one of the first steps to the future systems for evolution design of any universal structures in contrast with the evolution systems for design of a concrete type of structure. The result of this work is the basic system for evolutionary design of 3D structures with the ability of external fitness function definition via the XML file. This paper offers also the simple advices and observations for the potential future work in this area.

Building Model Generator for Open Street Maps
Libosvár, Jakub ; Láník, Aleš (referee) ; Polok, Lukáš (advisor)
This thesis deals with the procedural generation of building models based on a given pattern. The community project OpenStreetMap is used for obtaining datasets that create the buildings platform patterns. A brief survey of classifiers and formal grammars for modeling is introduced. Designing an estate classifier and algorithm for building generation is practical aspect of this thesis, including the algorithm implementation. 3D output meshes are rendered using OpenGL in real-time.

L Systems and Their Applications
Koutný, Jiří ; Goldefus, Filip (referee) ; Meduna, Alexandr (advisor)
This master thesis describes deterministic context-free L-systems and its context in procedural modeling, especially in fractal geometry, deals with rewriting technique and its usage for modeling structures similar to plants. Further it describes more complex types of L-systems, especially their context and parametric variations, and shows usage of L-systems in computer graphics and describes its usage for procedural modeling of architecture. At the end of this thesis there are described some other possibilities of usage procedural modeling with L-systems and introduced some extensions of rewriting rules, which will be subject of future research.

Methods of Generating Plants for Computer Graphics
Picek, Jiří ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
This Bachelor's thesis deals with methods useable for a plant generation for computer graphics. Most detailed described method is generation by L-system. The thesis describes idividually extensions of 0L-systems. To get a geometric representation of model, the output of the L-system is proceed by turtle graphics. The geometric representation of model is drawn using OpenGL graphics library. Textures are generated by Perlin's noise function implemented in GLSL.

Mathematical methods of modelling the morphology of spruce trees
Janoutová, Růžena ; Novotný, Jan ; Pivovarník, Marek ; Zemek, František
Radiative transfer (RT) models are simulation tools which can be used to quantify relationships between vegetation canopy properties and observed remotely sensed data. Th is study aims at creating a spruce tree growth model as a key input for use in RT models. Th e spruce tree model is built on data obtained from terrestrial laser scanning of spruce trees. Each tree model is unique. Th is uniqueness is achieved by using L-systems which are able to simulate natural randomness while complying with the given tree parameters. L-systems are established on a theory of grammar that enables rewriting a string of symbols according to specifi ed rewriting rules. In practice, our tree models are generated in Blender visualization soft ware, implementing an algorithm written in Python. Th e algorithm generates the basic parameters of the whole tree and then creates the parameters of the spruce trunk and initial branches. Th e parameters are generated randomly within a range that is calculated from measured data. Th en each branch is grown on the basis of annual increments defi ned by fi eld measurements. Tree needles are distributed with respect to the age of individual branches; therefore, the needles have diff erent colours according to their age. Cones and faces are graphical representations of the spruce model. Branches are represented by cones and needles are represented by faces around the branches. Th e faces are transparent, thus simulating light transmittance in-between the needles. The whole model is highly computationally demanding, especially with respect to computer memory.
