Improvements of Shadow Rendering
Kobrtek, Jozef ; Kozlíková, Barbora (referee) ; Váša, Libor (referee) ; Herout, Adam (advisor)
Táto práca sa zaoberá inkrementálnym zlepšením techniky tieňových telies. V práci sa popisuje vylepšenie vykresľovania z pohľadu robustnosti kde bol navrhnutý nový spôsob deterministického výpočtu siluety na rôznych platformách. Táto technika bola v ďalšom kroku zjednodušená a celý algoritmus tieňových telies implementovaný prostredníctvom hardvérovej teselácie. Ďalej bola navrhnutá metóda akcelerovanej extrakcie siluety z modelu pomocou oktálového stromu. Navrhnuté metódy boli v závere porovnané s aktuálnymi modernými algoritmami s tvrdými všesmerovými tieňmi.

Adaptive Simulation of Large-Scale Ocean Surface
Krijt, Filip ; Kadleček, Petr (advisor)
Physically-driven methods of simulating fluid dynamics and frequency-based ocean surface synthesis methods are of long-standing interest for the field of computer graphics. However, they have been historically used separately or without any interaction between them. This thesis focuses on the possibility of combining the approaches into one adaptive solution by proposing methods for unified surface representation, method result blending and one-way interaction between the methods. The thesis also outlines several future developments of the combined method and proposes a level-of-detail approach taking advantage of hardware tessellation that can be used regardless of what method was used for the simulation.

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.

Advanced simulation methods for reliability analysis of structures
Gerasimov, Aleksei ; Lehký, David (referee) ; Vořechovský, Miroslav (advisor)
The thesis apply to reliability problems approach of Voronoi tessellation, typically used in the field of samples designs evaluation and for Monte Carlo samples reweighing. It is shown, this general technique estimation converges to that of Importance Sampling method despite it does not rely on Importance Sampling's auxiliary density. Consequently, reliability analysis could be divided into sampling itself and assessment of simulation results. As an extension of this idea, adaptive statistical sampling using QHull library was attempted.

Modelling of the randomly formed ceramic foam structure for FEM simulations
Papšík, Roman ; Navrátil, Petr (referee) ; Ševeček, Oldřich (advisor)
This bachelor thesis deals with construction of ceramic foam model with various levels of (ir)regularity for finite element simulations in Ansys. The main objective is to substitute the complex structure of the open cell foam using the beam elements, enabling to perform FE analysis on much larger volumes of foams than the realistic foam models composed of solid elements. In this work, the technique of the model creation is based on the Voronoi tessellation and enables choice of arbitrary (ir)regularity of the modelled structure. The created source codes generate the model data directly in the syntax of APDL language for FEM system Ansys. The first part of the work describes several methods of the space partitioning and methods for substitution of the real foam structure by simplified “wire” model. The second part defines the Voronoi tessellation (diagram) as a key technique for creation of the foam model and describes its algorithms. The next part of the work deals with possibilities and utilizations of various software and libraries, describes creation of the own code in mathematical software Matlab and way how to transfer the model data into the system Ansys. The last part of the work demonstrates functionality of the created model on several FEM simulations, studying response of the ceramic foam on the external mechanical loading, upon consideration of various levels of the foam structure irregularity.

Tool for Designing Procedural Textures
Číž, Miloslav ; Polok, Lukáš (referee) ; Milet, Tomáš (advisor)
This thesis deals with implementation of a program library for designing and generating two-dimensional procedural textures and its GUI supportive tool. Attention was paid to common methods as well as to other computer graphics areas with effort for modifying the algorithms in order to achieve unique results. An effective way of texture representation and its concrete implementation is also presented.
