Vector Font Rasterization on LCD
Hrušovský, Marek ; Přibyl, Jaroslav (referee) ; Granát, Jiří (advisor)
This bachelor's thesis deals with sub-pixel vector font representation. It generaly describes representation and rasterization of vector font and shortly compares advantages of vector font against bitmaped font. Including information about sub-pixel font representation on screen type LCD, possibilities and problems that this type of projection produces. It contains implementation description of demonstrational application, which rasterizes font with sub-pixel technology.

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.

Interactive apps for education of vector graphics theory
Lipa, Matúš ; Šeda, Pavel (referee) ; Rajmic, Pavel (advisor)
This work deals with the creation of several interactive web applets for education of vector graphics. Described is the image signal, his discretization, vector and bitmap types of image record. Further they describe selected vector curves, their properties, algorithms for their construction and usage. The principles of rasterization of basic vector objects are explained. Using the Figma tool, graphical user interfaces for each applet are designed. These applets are implemented using HTML and Javascript. The implemented applets are placed on web pages that are used in computer graphics education.

Education Computer Program for Demonstration of 2D Shapes Rasterization
Krupička, Vojtěch ; Kubíček, Radek (referee) ; Štancl, Vít (advisor)
This bachelor thesis deals with the problem of rasterization of vector objects on display devices (e.g. computer screen). The rasterization is one of the most important phenomena in computer graphics. The knowledge of mathematical equations and formulas which describe relevant vector objects is necessary to understand this phenomenon. This education software for the visual demonstration of rasterization was created to familiarize users with the rasterization principles of selected vector objects.

Teaching aids for 2D computer graphics
Malina, Jakub ; Průša, Zdeněk (referee) ; Rajmic, Pavel (advisor)
In this master’s thesis we focus on the basic properties of computer curves and their practical applicability. We explain how the curve can be understood in general, what are polynomial curves and their composing possibilities. Then we focus on the description of Bezier curves, especially the Bezier cubic. We discuss in more detail some of fundamental algorithms that are used for modelling these curves on computers and then we will show their practical interpretation. Then we explain non uniform rational B-spline curves and De Boor algorithm. In the end we discuss topic rasterization of segment, thick line, circle and ellipse. The aim of master’s thesis is the creation of the set of interactive applets, simulating some of the methods and algorithm we discussed in theoretical part. This applets will help facilitate understanding and will make the teaching more effective.

Education Computer Program for Demonstration of 2D Objects Generation in Raster
Šůs, Martin ; Šiler, Ondřej (referee) ; Kršek, Přemysl (advisor)
There are discussed the differences between raster graphic and vector graphic in the first, the theoretical part of the thesis. Their pros and cons are mentioned and the importance of conversions between this two types of graphics is explained. Process of rasterization, conversion from vector graphic to raster graphic, for selected graphic primitives/entities is thoroughly described. The second part describes the process of development and implementation of the application.
