3D Object Vizualization Represented by Boundary Points
Hezina, Luděk ; Herout, Adam (referee) ; Kršek, Přemysl (advisor)
The aim of my bachelor thesis was to create the system for visualization of 3D objects which are representated by boundary points. Thesis is written in C++ language. I have used the library OpenSceneGraph for creation of windows, manipulation with scene and for loading objects from external files. The system includes two integrated generators of implicit objects.

Volume Rendering Using Programmable HW
Jošth, Radovan ; Kršek, Přemysl (referee) ; Herout, Adam (advisor)
This work describes and implementing method for volume data rendering. Main purpose of this work is visualization of scanned 3D data with some current method used for the 3D volumetric scanning. The 3D volumetric scanning is mainly used in medicine and chemistry. System is using programmable pipeline of current graphic cards, which provides us fast parallel work with large volumetric data. This paper introduces some basics about the volumetric rendering and scanning, describes design and at the end, the implementation steps. Result of this project is application which renders volumetric data with OpenGL.

Interactive Medical Image Segmentation
Olša, Martin ; Kršek, Přemysl (referee) ; Španěl, Michal (advisor)
This work deals with a fast level-set approach for segmentation of anatomical structures in volumetric medical images. The fast level-set method evolves a closed 3D surface in time propagating the surface form an initial position. The major contribution of this work is the implementation of the level-set method and construction of an interactive tool for segmentation of 3D medical data using this method. The tool is able to interactively change parameters of the evolution during the segmentation process itself. Due to the nature of level-set method, the evolution process can be stopped at any time, or backtracked and restarted from any previous step with a different configuration.

Rendering Complex 3D Scenes
Mrkvička, Tomáš ; Kršek, Přemysl (referee) ; Herout, Adam (advisor)
This thesis deals with representation of large and complex 3D scenes which are usually used by modern computer games. Main aim is design and implementation of data driven rendering system. Proper rendering is directed (driven) by scene description. This description is also designed with respect to scene creators whose typically do not have deep knowledge of programming languages in contrast to game programming developers. First part is focused on design of efficient scene description and its possible applications at scene rendering. Second part is focused on proper system implementation. Finally, consequently important system optimizations are mentioned too.

Level of Detail (LOD) Algorithms in OpenSceneGraph Library
Koukolíček, Ondřej ; Kršek, Přemysl (referee) ; Pečiva, Jan (advisor)
The aim of this thesis is to explore and evaluate capabilities of the OpenSceneGraph library in the field of level of detail (LOD) algorithms. It contains introduction to the LOD issues and detailed description of techniques that are used in conjunction with this technology. Furthermore it analyses those tools available in OSG, which can be used to create an application utilizing LOD. The main part of the thesis is focused on description of design and implementation of application, which uses the LOD capabilities of OSG as well as own extension to these methods. In the conclusion, the resulting application is subjugated to a benchmark and the OpenSceneGraph librarys LOD capabilities are evaluated.

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.

Defining and Fulfilling Tasks in 3D Space for Several Users
Kudlač, Boris ; Kršek, Přemysl (referee) ; Herout, Adam (advisor)
The goal of this thesis is to create system for setting and completing objectives in 3D multiplayer space, in particular for project TankGame. This project is a simulation of tank battles and thesis adds a new feature to it, which is setting and detecting any objectives for single and multiplayer game. In the same time, it demonstrates its capabilities by implementing a deathmatch game for 2 or more players.

Polygonal Models Smoothing
Nečas, Ondřej ; Herout, Adam (referee) ; Kršek, Přemysl (advisor)
The result of digitalization 3d surface is affected by many factors. After digitalization can on the surface emerge some unwanted artefacts. The differences from original are caused by resolution of the device or its limited precision. For elimination of this artefact exists many smoothing algorithms, but we want to choose that which best suits this purpose. So it is useful to know their limits and characteristics.
