3D Triangles Polygonal Mesh Conversion on 3D Spline Surfaces
Jahn, Zdeněk ; Španěl, Michal (referee) ; Kršek, Přemysl (advisor)
This bachelor's thesis deals with the problem of the remeshing of unstructured triangular 3D meshes to more suitable representations ( quadrilateral meshes or spline surfaces ). It explains the basic problems related with the unstructured meshes and the reasons for its solution. It classifies the usable methods, describes the most suitable candidates briefly. It follows the chosen method in detail - both the theoretical matter and the specific implementation.

Visualization of Large Data Sets
Mokroš, Petr ; Chudý, Peter (referee) ; Přibyl, Jaroslav (advisor)
Work is focused on visualization of large data sets, especially on high resolution terrain models. Thus the goal of this work is to design a library which can divide large models to small regular parts for fast render of whole scene using level of detail techniques. Further goal is theoretical analysis how the library for fast and smooth visualization of large scenes in real time can be used.

Fast Implementation of Geometric Algorithms
Krba, Martin ; Jošth, Radovan (referee) ; Havel, Jiří (advisor)
One of the most often used calculations in computer graphics is detection of collision between ray of light and triangle on the surface of object in 3D space. This frequent usage is motivation to search for the best methods for this calculations. This thesis contains explanation of basics of this topic and also testing of methods with real input data to better and accurate comparison.

Cathedral today
Rampáčková, Monika ; Mléčka, Jan (referee) ; Štěpán, Marek (advisor)
The master's thesis deals with famous Notre-Dame de Paris, which was destroyed by fire in 2019. The work focuses specifically on the design of completion of the construction. The cathedral is situated in the historical centre of Paris on the Île de la Cité. A lot of damage was caused to the building after the devastating fire on 15 April 2019. The aim of the thesis was to create a spiritual place that would maintain its past, but at the same time manage to follow ecological solutions in the present. The new design of the attic creates a sacred place, in which we realize the importance of faith and the peace of God. The cathedral is open to the general public ? religious people from all over the world come here to experience the love, joy and happiness that the cathedral invokes. The whole attic can be described as an open space, which symbolizes infinity or immortality from the religious point of view. It represents the connection of the past, present and future. The space is designed to hold priestly celebrations and to be open for the public. It can also be used for various events, such as exhibitions of sculptures that survived the fire.

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.

Fast Ray-Triangle Intersection
Havel, Jiří ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
Triangle is the mostly used primitive in computer graphics. Calculation of its intersection with a ray has many applications and is often a bottleneck of a program. This work focuses on its usage and various methods of calculation. It tries to combine these techniques to achieve high performance on modern processors.

Fast Ray-Triangle Intersection
Horák, František ; Navrátil, Jan (referee) ; Havel, Jiří (advisor)
This work contains a few basic terms of analytical geometry. We mention some of ray-triangle intersection computation algorithms and present some use-case examples. We discuss capabilities of CUDA, optimization techniques of this architecture and implementation with focus on given issues. Algorithms of ray-triangle intersection are tested and results are discussed.

Presentation Software - Triangle Basic Facts
Kašparová, Šárka ; Švub, Miroslav (referee) ; Štancl, Vít (advisor)
This bachelor's thesis is about development of presentation software supporting teaching of mathematics - triangle basic geometrical facts. It suggests basic knowledge about education and triangles. The second part is about analysis and implementation of the program and tools that were applied in its development.
