The research evaluates the feasibility of assisting orthodontists to treat irregularities in teeth by computing the transformations to move each tooth to its ideal position. The intent is to help orthodontists craft a precise and specific treatment plan for each patient. Computation of the transformations is achieved through the use of a reverse engineering package, Geomagic Studio, and a three dimensional modeling program, Rhino3D. The inputs for finding the transformation are the patient's teeth mold and dental arch templates. A 3D laser scanner is used to form a point cloud data representation of the patient's teeth mold. Geomagic is used to construct a Non-Uniform Rational B-Spline surface for the mold. Rhino3D is used to manipulate this surface and compute the required transformations using the scripting platform, Rhinoscript, in Rhino3D. The steps in the process and the algorithms developed in Rhinoscript to compute the transformations are discussed. Three case studies are presented to demonstrate the process. / text

The goal of this thesis is to scan part of castle Rokštejn using terrestrial laser scanner and from obtained data draw up a 3D model. Model is made with a method using meshing. In this work I also deal with the software, which supports meshing, and evaluating pros and cons of each program. The output of this work is 3D model which will serve to better representation of the current state of the castle and its better documentation.

Im Rahmen des Forschungsprojektes ,,Entwicklung eines 3D Hochgeschwindigkeits-Rotationsdruckverfahren' an der Hochschule Mittweida, wird sich mit dem Erzeugen eines CAD-Modells eines Patientenschädels und der passgenauen Modellierung einer orthopädischen Helmschale für diesen beschäftigt. Ziel ist es die zeitintensive Modellherstellung mittels Gips einzusparen und die endgültige Helmschale im .stl-Format zu erzeugen. Weiter wird, mittels einer visuellen Programmierumgebung, ein Programm erzeugt um die Helmschale in einem polaren Koordinatensystem für den geplanten Hochgeschwindigkeits-Rotations-3D-Drucker auszurichten, zu slicen und die Koordinaten der einzelnen Punkte der Bahnkurven der Extruder auszugeben.

This diploma thesis deals with the design and implementation of appropriate procedure photogrammetry processing of technical documentation of selected historical artifacts gauges. During processing was calibrated camera, historical gauges were photographed and metrological documented and model viualization was created.
