Blender add-on for Astronomical Object Generation
Hlávka, Marek ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
Procedural modeling methods greatly facilitate the process of modeling 3D objects that mimic real-world elements, which needs to be performed more and more efficiently. This thesis deals with procedural modeling of astronomical objects and their modification. It also deals with design, implementation and publication of an add-on for the open-source program Blender, that enables modeling of these objects. The add-on is implemented in Python using the Blender API. As a result, Blender is extended with an interface for fast and convenient generation of astronomical objects. The published add-on is available open-source.

Generating Procedural Planets
Fusek, Petr ; Polášek, Tomáš (referee) ; Starka, Tomáš (advisor)
This bachelor's thesis deals with the design and implementation of an easily extensible library for creating generators of procedural planet surfaces. The aim of the library is to enable the use of originally two-dimensional methods of procedural map generation to generate a contextually rich planet surface. The library emphasizes the extensibility and simplicity of working with the generated surface. It allows the user to create and parameterize their own generators and use their own algorithms in them. It also includes an implemented planetary elevation map generator that uses a simplified model of simulating tectonic plate collisions to generate a surface with a topology containing mountains, bays and archipelagos. Such a surface should show visual results closer to reality than the classical approach using procedural noises allows. The library is implemented together with a visualization application presenting the generated surfaces and allowing to set all possible inputs of the generator using the GUI.

Forward and Inverse Modeling of Planetary Gravity and Topography
Pauer, Martin ; Čadek, Ondřej (advisor) ; Martinec, Zdeněk (referee) ; Novák, Pavel (referee)
Title: Forward and Inverse Modeling of Planetary Gravity and Topography Author: Martin Pauer Department/Institute: Department of Geophysics MFF UK Supervisor of the doctoral thesis: Doc. RNDr. Ondřej Čadek, CSc., Department of Geophysics MFF UK Abstract: The aim of this work was to investigate various mechanisms compensating the observed planetary topography - crustal isostasy, elastic support and dynamic support caused by mantle flow. The investigated models were applied to three different planetary problems. Firstly we applied dynamic compensation model to explain today large-scale gravity and topography fields of Venus and investigate its mantle viscosity structure. The results seem to support not only models with constant viscosity structure but also a model with a stiff lithosphere and a gradual increase of viscosity toward a core. In the second paper several crust compensation models were employed to estimate the density of the Martian southern highlands crust. Since the used methods depends differently on crustal density changes, we were able to provide some constraints on the maximum density of the studied region. In the third application, the strength of a possible ocean floor gravity signal of Jupiter's moon Europa was studied. It turned out that if the long wavelength topography reaches height at...
