Acceleration of Graphics Operations by Means FPGA
Čapka, Ladislav ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
This term project is aimed on analysis of graphic pipeline which can rasterize required picture. Document is specialized to drawing algorithms that are used in rasterization block. Major aim of this project is describing of rasterization algorithms that can be implemented on hardware. Type of aimed hardware is field-programmable gate array FPGA.
3D Triangles Polygonal Mesh Conversion on 3D Spline Surfaces
Jahn, Zdeněk ; Šiler, Ondřej (referee) ; Kršek, Přemysl (advisor)
In computer graphics we can handle unstructured triangular 3D meshes which are not too usable for processing through their irregularity. In these situations it occurs need of conversion that 3D mesh to more suitable representation. Some kind of 3D spline surface can be proper alternative because it institutes regularity in the form of control points grid and that's why it is more suitable for next processing. During conversion, which is described in this thesis, quadrilateral 3D mesh is constructed at first. This mesh has regular structure but mainly the structure corresponds to structure of control points grid of resulting 3D spline surface. Created quadrilateral 3D mesh can be saved and consequently used in specific modeling applications for T-spline surface creation.
Automatic Producing of Cranial Implant Edge Surface
Hrdý, Libor ; Bartoň, Radek (referee) ; Kršek, Přemysl (advisor)

Interpolation with NURBS curves
Škvarenina, Ľubomír ; Rajmic, Pavel (referee) ; Zátyik, Ján (advisor)
Diploma thesis deals with image interpolation. The aim of this work is to study theoretically and then describe the nature of the various methods of image interpolation and some of them implemented in the program MATLAB. The introductory part of this work theoretically closer to important terms that are closely related to this topic of digital image processing sufficient to understand the principle. In the following of the thesis will be discussed all of today's commonly used method of image interpolation. Will hear all about the method of image interpolation using nearest neightbor interpolation and image help of polynimals such as (bi)linear, (bi)quadratic and (bi)kubic method. Then work theoretically analyzes the theory of individual species curves and splines. More specifically, coming to their most frequently used variants of B-spline curves and ther generalizations called NURBS, with addressing the problem of interpolating these curves. The final chapter consists of the results achieved in the program MATLAB.
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.

Comparison of qualitative properties of NURBS interpolation curves
Halas, David ; Procházková, Jana (referee) ; Hoderová, Jana (advisor)
This thesis deals with simple interpolation curves, which are clamped. Construction of the curves is solved by several forming tools. There is also brought procedure of their calculation. Result is comparating different interpolation methods. The thesis is useful to understanding for interpolation NURBS curves and for choosing apposite forming methods.
Frictionless contact of elastic bodies: comparison of treatment in finite element analysi and isogeometric analysis
Kopačka, Ján ; Kolman, Radek ; Gabriel, Dušan ; Plešek, Jiří
Artificial oscillations in contact force due to non-smooth contact surface are treated by isogeometric analysis (IGA). After brief overview of B-splines and Non-Uniform Rational B-Splines (NURBS) representation, the mortar-based contact algorithm is presented in the frictionless small deformation regime. Contact constraints are regularized by penalty method. The contact algorithm is tested by means of contact patch test.
