Graphics Intro 64kB Using OpenGL
Věrný, Jan ; Matýšek, Michal (referee) ; Milet, Tomáš (advisor)
This bachelor's thesis deals with creation of graphic intro with limited size of the produced executable file. To reach this goal OpenGL, together with procedural generation techniques, exe packer and various compiler settings were used. The result is an executable file with size not going over 64kB, which shows Martian spaceships travelling towards the planet Earth.

4K Video Player for Virtual Reality
Chvíla, Václav ; Matýšek, Michal (referee) ; Kobrtek, Jozef (advisor)
The subject of this work is the implementation of 4K video player for virtual reality. Theoretical part describes the origin of 360° videos, their compressions and rendering. In design of application was choosed solution with OpenGL, OpenVR, Qt libraries and commercial codec jpeg2000 developed by Comprimato company and for virtual reality device the HTC Vive headset. In part of implementation is analysed problem of shared video memory between libraries and discusses optimalization of the video player. Application was tested in perfomance and by users.

Boolean Operations for Polygonal Meshes
Čižmarik, Roman ; Matýšek, Michal (referee) ; Španěl, Michal (advisor)
The aim of this work is to create a library for Boolean operations on 3D polygonal meshes. Resulting library has to support open models, its memory requirements shouldn't exceed those of existing solutions and it should, ideally, support multiple models. Most of the existing solutions are vulnerable to arithmetic inaccuracies, or do not support open meshes. The solution is based on Adaptive Mesh Booleans method which treats input models as adaptive surfaces. This method assumes that input models can be arbitrarily refined and no individual polygon is particularly important. Instead of computing exact polygon intersections, the input meshes are refined in intersection regions, intersecting polygons are discarded and created holes are closed. Advantages of this approach are robustness against numerical errors, support for open meshes, possibility to trade accuracy for computation time and ability to solve cases like co-planar and near-coincident regions. The resulting library offers three Boolean operations: union, difference and intersection.

Graphics Intro 64kB Using OpenGL
Minařík, Antonín ; Matýšek, Michal (referee) ; Herout, Adam (advisor)
This thesis deals with creating a graphics intro, which's size has to be below 64~kB. Described and used techniques includes: Phong reflection model, fog, skybox, generating textures from noise and shadow mapping. Intro is placed in a city and techniques of generating elements of the city are described. In addition, there are described methods for reducing file size and system for camera animation.

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.

Graphics Intro 64kB Using OpenGL
Baáš, Andrej ; Matýšek, Michal (referee) ; Herout, Adam (advisor)
This thesis deals with the creation of a graphic intro with limited size. This work describes methods and techniques for generating the graphic content. It deals with procedural generation of textures and objects, creation of particle systems, lighting and animation of selected objects. It describes methods for reducing the size of the final application. The result is a graphical intro showing an underwater environment with a coral reef and floating fish whose size is less than 64kB.

Complex Scene Rendering on Mobile Devices
Matýšek, Michal ; Polok, Lukáš (referee) ; Kajan, Rudolf (advisor)
This thesis presents optimization techniques for efficient rendering of complex scenes on mobile devices. The introductory part of the text describes Unity game engine and the topic of mobile game development using this tool. Then follows a presentation of important optimization principles and methods for terrain rendering, large scale rendering of animated objects, rendering of animated water surfaces and of other elements in the scenes. The described methods include both general principles of optimization and specific optimization approaches based on the features of Unity game engine. The implementation of presented methods is described and used in practice in the context of mobile strategy game development.

Graphics Demo Employing Procedural Textures
Drevický, Dušan ; Matýšek, Michal (referee) ; Polok, Lukáš (advisor)
This thesis deals with the design and implementation of a size-limited 64 kB graphics demo. Procedural generation is used for the definition of structure and appearance of realistic natural terrain. The terrain is described by a heightmap based on noise functions described in this work. Rendering utilizes the ray marching method and is done in real time. All parts of the implementation described in this work were created exclusively within the fragment shader of the GPU.

AC/DC adjustable power converter 5 - 30 V / 30 A
Matýsek, Michal ; Brančík, Lubomír (referee) ; Petržela, Jiří (advisor)
This work deals with the switched mode power supplies, their possible solutions and consequently with design of a power source with given parameters. The theoretical part analyses behaviour of the switched mode power supplies. Further it contains a survey of wiring of AC/DC converters and their properties. In the framework of the practical part was developer the power AC/DC switching power supply with adjustable output voltage from 5 to 30 V and 30 A current. The source was designed as a half-bridge decreasing converter with a transformer.

Differential and Common Mode Conducted Emissions Measurement
Matýsek, Michal ; Soldán, Josef (referee) ; Dřínovský, Jiří (advisor)
This work deals with interfering signals and noises, possibilities of their measurement, their reduction and afterwards with design of LISN. The theoretical part analyzes formation of interfering signals, their types, with possible measuring instruments for each type of these signals and their properties. In framework of practical part LISN for long-term load of 5A, frequency range from 150 kHz to 30 MHz, with possibility to measure symmetrical and asymmetrical noise separately and also with possibility to switch to normal mode of LISN was developed. For better results LISN was realized as two stage LC filter.
