Polygonal Mesh Segmentation
Bezděčík, Ladislav ; Polášek, Tomáš (referee) ; Španěl, Michal (advisor)
This bachelor's thesis deals with the issues of segmentating 3D models of human jaws. It analyzes currently used methods and proposes, implements and tests possible improvement to these methods from user perspective. The proposal consists of using neural networks for topology recognition on jaw models, and possibly combining this topology with currently used segmentation methods. This thesis also analyzes and implements the possibility of automated expnansion of 3D model datasets converted to depth maps, used for neural network training.
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.
Simulation of Snow and Ice Features
Čech, Ondřej ; Polášek, Tomáš (referee) ; Čadík, Martin (advisor)
This project focuses on simulation of formation of glaciers known as Penitentes. It is based on mathematical model of formation of these structures by M. D. Betterton. Implementation is done in C++ programming language, and the result is exported as bitmap image containing heightmap, which can be rendered using Blender.
Hybrid Raytracing in DXR
Polášek, Tomáš ; Matýšek, Michal (referee) ; Kobrtek, Jozef (advisor)
The goal of this thesis is to evaluate the usability of hardware accelerated ray tracing in near-future rendering engines. Specifically, DirectX Ray Tracing API and Nvidia Turing architecture are being examined. Design and implementation of a hybrid rendering engine with support for hardware accelerated ray tracing is included and used in implementation of frequently used graphical effects -- hard and soft shadows, reflections, and Ambient Occlusion. The assessment is made in terms of difficulty of integration into a rendering engine, performance of the resulting system and suitability of implementation of chosen graphical effects. Performance parameters -- including number of rays cast per second, time to build acceleration structures and computation time on the GPU -- are tested and discussed.
Graphic Engine Based on Entity Component System
Polášek, Tomáš ; Matýšek, Michal (referee) ; Španěl, Michal (advisor)
The goal of this bachelor thesis is the design and implementation of a library for entity management which allows software development using the Entity-Component-System paradigm. Analysis of the current state of software design is presented, including comparison of techniques used for entity representation. Potential advantages of composition are discussed from the hardware point of view, primarily based on the memory hierarchy found in modern computers. Thesis proposes design of an entity system, using the ECS paradigm, which allows dynamic composition of entities during runtime of application from predefined components. The resulting system is designed to allow for easy parallelization of performed actions and user customizability of component data structures. The result of this bachelor thesis is a C++ multi-platform library, named Entropy , which enables its users to design applications using the ECS paradigm.
Probíhající reformy v zemích zálivu a jejich dopad na pozici USA v regionu
Antolík, Tomáš ; Pešková, Vladimíra (advisor) ; Polášek, Tomáš (referee)
This work evaluates the current situation in the six member states of the Gulf Cooperation Council. The main areas of evaluation are the ongoing reforms, the proposed monetary union and the relationship with the United States. As for the reforms, the main focus is the transition from a closed to an open market economy and the mitigation of their oil dependence. Furthermore, the following chapter deals with an analysis of the Optimum Currency Area for the GCC region. Finally, the last chapter is aimed to provide a brief insight into the US-GCC relationship and its prospects in the near future.
