Building Model Generator for Open Street Maps
Galacz, Roman ; Poulíček, Zbyněk (referee) ; Polok, Lukáš (advisor)
This work concerns obtaining data from the maps provided by the project OpenStreetMap. The data are converted from the format of geographical latitude and longitude to the Cartesian coordinate system. This work also concerns building type recognition in build-up area which are situated on the downloaded map. Part of the work is a demonstration application which is able to model 3D geometry of the buildings, based on the results of the recognition algorithms and also creates a terrain in which these buildings are situated. Generated model is displayed using the OpenGL graphics library.

Photon Tracing on GPU
Galacz, Roman ; Navrátil, Jan (referee) ; Polok, Lukáš (advisor)
Subject of this thesis is acceleration of the photon mapping method on a graphic card. The photon mapping is a method for computing almost realistic global illumination of the scene. The computation itself is relatively time-consuming, so the acceleration of it is a hot issue in the field of computer graphics. The photon mapping is described in detail from photon tracing to rendering of the scene. The thesis is then focused on spatial subdivision structures, especially to the uniform grid. The design and the implementation of the application computing the photon mapping on GPU, which is achieved by OpenGL and CUDA interoperability, is described in the next part of the thesis. Lastly, the application is tested properly. The achieved results are reviewed in the conclusion of the thesis.
