Photorealistic Rendering
Lysek, Tomáš ; Kučiš, Michal (referee) ; Zemčík, Pavel (advisor)
The thesis describes implementation of photorealistic method. The first part describes the procedures and techniques, that are used to display photorealistic scenes such as raytracing, radiosity or photon mapping and other techniques used in computer graphics. The second part of thesis is focused on evaluation of current state of problem. In this part is also described reason of choosing this topic and thesis assignment is there more specified. The last part of thesis is focused on implementation details of photorealistic method.

Improvements of Shadow Rendering
Kobrtek, Jozef ; Kozlíková, Barbora (referee) ; Váša, Libor (referee) ; Herout, Adam (advisor)
Táto práca sa zaoberá inkrementálnym zlepšením techniky tieňových telies. V práci sa popisuje vylepšenie vykresľovania z pohľadu robustnosti kde bol navrhnutý nový spôsob deterministického výpočtu siluety na rôznych platformách. Táto technika bola v ďalšom kroku zjednodušená a celý algoritmus tieňových telies implementovaný prostredníctvom hardvérovej teselácie. Ďalej bola navrhnutá metóda akcelerovanej extrakcie siluety z modelu pomocou oktálového stromu. Navrhnuté metódy boli v závere porovnané s aktuálnymi modernými algoritmami s tvrdými všesmerovými tieňmi.

3D Map Building Based on Stereo Vision for Mobile Robot Navigation
Babinec, Adam ; Orság, Filip (referee) ; Herman, David (advisor)
This thesis is dedicated to the subject of passive stereo vision in modern robotics. The work includes the design and implementation of autonomous passive binocular stereo vision system for mobile robot navigation. A three-dimensional local map is built up by aggregation of point clouds created by reprojection of the image pairs taken with stereocamera. The image pairs are reprojected using disparity map obtained with application of block matching algorithms on the image pairs. The local map is represented by voxel grid stored in an octree and it supports detection of moving obstacles on ray-casting principle. Visual odometry is calculated by tracking reprojected paired image features detected in series of image pairs. The system allows user to choose different approaches to the problem solving, it is platform and hardware-independent and provides graphic user interface.

3D laser range finder SICK application
Fritz, Tomáš ; Krček, Petr (referee) ; Marada, Tomáš (advisor)
This thesis presents a use of 3D laser range finder designed for purposes of autnonomous mobile systems. The 3D scanner is built as extension of 2D laser range finder with rotation module. In the first section is described laser range finder SICK LMS 291 and his pitching construction along with used software tools. Second part deals with design and implementation of algorithms for data reading and their processing with methods of surface reconstruction, octree and object segmentation with Hough transform.

Blender Plugin for Conversion of Models to Vector Graphic
Kopáček, Jiří ; Chlubna, Tomáš (referee) ; Milet, Tomáš (advisor)
This thesis deals with the design and implementation of an extension (plugin) for Blender software. This extensions adds the feature of converting 3D models in a Blender scene to a 2D vector graphics file in the SVG format that represents the original scene. The thesis focuses on creating the plugin's user interface, conversion of vertex coordinates from 3D scene to 2D window coordinates, calculating the resulting polygon color based on lighting and material, cutting of conflicting (colliding) objects and determining the order in which the resulting polygons have to be drawn. The result of the implementation is a plugin that allows the user to create 3D models which can be converted (snapshot) to SVG formatted vector graphics files, instead of manually creating 2D vector images.

Acceleration Structure Building on GPU
Hába, Jiří ; Kula, Michal (referee) ; Starka, Tomáš (advisor)
This thesis focuses on the construction of octree for three-dimensional triangular models on graphics hardware. This acceleration structure was chosen based on a comparison of the most commonly used acceleration structures. The approach to the construction of this structure is based on the method of construction of a sparse voxel octree which is derived from the former. The process uses voxelization accelerated by the graphics card's rendering pipeline. To facilitate this process and enable the integration of the proposed procedure into future applications, this thesis also includes design of a C++ language library.
