Simple 3D Printer Simulator
Čillo, Vladimír ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
This thesis deals with design and implementation of 3D printer simulator in C++ using Qt. The simulator assumes a printer based on widely used method of 3D print - Fused Deposition Modeling. An input of simulator is a 3D model in STL file format. For the 3D model simulator provides an estimate of the total print time. Simulation also includes visualization of 3D print. The result is a cross-plaform program tested under Linux and Windows. Functionality of simulator has been tested by several experiments.

Bridge on a interchange in Brno
Kyzlink, Lukáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
Diploma thesis describes the design and assessment of bridge supporting structure on the ramp in Brno. Road bridge crosses the I/42 road and railway. The bridge is part of the VMO Brno. The structure is designed from prestressed concrete. Assessment of construction is carried out in accordance with applicable European standards. When designing the support structure is taken into account the gradual construction of the bridge. The thesis includes design calculation, drawing documentation and 3D visualization.

Micro CT 3D visualization and analysis of collagen scaffolds
Jakubíček, R. ; Chmelík J.
In this paper we describe proposed methodology of image processing of collagen scaffolds. The description and visualization of the 3D porous structure is essential for tissue regeneration. First part of work deals with delimitation of fibrillar and cellular structure of collagen using local adaptive cluster analysis with fuzzy logic. In next section the segmentation of pores and subsequent analysis of structure features is reported. Eventually, we illustrate and discuss achieved results.

Production logistics of printed circuits desks
Susko, Petr ; Starý, Jiří (referee) ; Špinka, Jiří (advisor)
This thesis describes the design of a new plant for the production of printed circuit boards with a capacity of 40,000 square meters per year. Describes the basic principles of a new production, production logistics principles and technological design, procedure for application of the method SLP, placement of production areas and capacity calculation of employees and machines. It also describes the technological process of production of printed circuit boards with subtractive method and discusses the different steps of production with regard to the proposed production. The practical part deals with the actual realization of the project, a selection of production technology, machinery, design the layout of the building, capacity calculations, deployment tools, practical application of the method SLP, visualization of production in the Plavis VisTable software, waste management and economic evaluation of project costs.

3D Scanning with Proximity Planar Scanner
Chromý, Adam ; Burian, František (referee) ; Žalud, Luděk (advisor)
Tato práce popisuje konstrukci skenovacího systému pro tvorbu trojrozměrných modelů. Kombinace laserového scanneru a robotického manipulátoru tvoří velice flexibilní zařízení schopné snímat jak velké, tak malé a detailní objekty. Zařízení nachází uplatnění v mnoha aplikacích, zejména v lékařství, kde přináší řadu nesporných výhod proti stávajícím systémům. Práce popisuje mechanickou konstrukci zařízení, funkční principy a jeho kalibrační proceduru. Součástí práce je i software pro vizualizaci naměřených dat a jejich zpracování do podoby modelů se stínovaným povrchem. Výsledkem práce je funkční zařízení a rozsáhlý obslužný software.

Simulation models of human operator.
Boháč, Petr ; Horák, Karel (referee) ; Havlíková, Marie (advisor)
This paper deals with simulation models of the human operator controlling lateral position of simulated vehicle. I am comparing parameters and quality of the McRuer human driver model and the PID controller. Simulated system is single-track vehicle model. Simulated driver is tasked to pass a Moose test with this vehicle model. I am using the simulated annealing method to find optimal parameters of the driver model and then I visualize realized test in 2D and 3D visualization. In the end of this paper I compare simulations of the driver models and assess achieved results.

Interactive Java applet used for 3D optic nerve head visualization
Šikl, Jaroslav ; Kolář, Radim (referee) ; Peter, Roman (advisor)
The aim of this thesis was to design and implement the interactive Java applet used for topography 3D optic nerve head visualization. Primary purpose of the 3D vizualization is ophthalmology, especially for diagnosis of glaucoma. More over should serve as a training material, which enables to study the transformation of 2D figures to 3D model and to test the effects of adjustments and regulations to imaging of the model in 3D space. Two program versions were designed in this work using the development system NetBeans version 5.5. Their final realization is implemented as .html application working in web browser window. First version of the designed applet is simple intuitive application with several default settings, so that the figure is opened automatically to 3D model. Subsequently, the applet enables to set the size of the image, 3D depth of the image, smoothing of the surface and selection of monochrome or coloured image. The second version is the extension of the first version of the designed applet, and provides the possibility to display x, y, z axis, depiction of the 3D model surface by dots, curves or grid, and illumination of the surface. Software was tested on available topographic data acquired by HRT equipment and in different web browsers. Technical documentation and user’s manual are also involved in this thesis.

Nástroje pro trojrozměrnou vizualizaci struktur v biologii
Čapek, Martin ; Janáček, Jiří ; Kubínová, Lucie ; Smrčka, P. ; Hána, K.
By consecutive scanning of layers of the biological specimen by a confocal microscope we obtain a stack of optical sections, i.e. a 3D digital representation of the specimen. Our research focuses, on volume reconstruction of large biological tissues, i.e. tissues greater than field of view and/or thicker than maximal depth of scanning of the confocal microscope. As a result of volume reconstruction we obtain a high resolution 3D image of the biological specimen. In order to visualize 3D objects on 2D computer screens we developed several tools including visualization by a specialized VolumePro board and by using consumer graphics cards supporting DirectX and OpenGL

3D vizualizace velkých biologických vzorků nasnímaných konfokálním mikroskopem
Čapek, Martin ; Janáček, Jiří ; Karen, Petr ; Kubínová, Lucie ; Smrčka, P. ; Hána, K.
Digital volume reconstruction is a technique for rendering and visualization of a biological specimen which is greater than the field of view of a used optical instrument - a confocal laser scanning microscope in our case. Prior to the volume reconstruction, large biological specimens are cut to thin physical slices. The first step of volume reconstruction is acquisition of sets of digital volume images (spatial tiles which overlap) from all studied physical slices. The second step is composition of neighbouring spatial tiles of the same physical slice. The third reconstruction step is registration and merging of digital volumes of neighbouring physical slices of the specimen. The resulting large digital volumes are rendered and visualized using a VolumePro hardware board that offers real-time 3D volume rendering. In this paper we show a reconstruction of a chick embryonic kidney
