Innovative Project 3D Technology

For questions concerning the Innovative Project 3D Technology at Vienna University of Technology please contact us via 3dtechnik(at)geometrie.tuwien.ac.at.

This website is provided by the Geometric Modeling and Industrial Geometry Research Unit, more information on our research can be found at http://www.geometrie.tuwien.ac.at/ig/.

An overview about the research activities is given in the following Forschungsnachricht (in German).

Aims and Scope

The innovative project 3D Technology is concerned with the acquisition, processing, understanding, and reconstruction of 3D data. The corresponding technical, numerical, and algorithmic problems are studied at the cooperating institutes at Vienna University of Technology.

Das innovative Projekt 3D-Technik beschäftigt sich mit der Aufnahme dreidimensionaler Objekte, der Verarbeitung der Aufnahmedaten und dem dreidimensionalen `Ausdrucken' (Fertigen von Prototypen) von Objekten. Die dabei zu lösenden technischen und algorithmischen Probleme werden an verschiedenen kooperierenden Instituten der Technischen Universität Wien behandelt. Ein Schlüsselpunkt dabei ist die Aufnahme realistischer Daten und eine direkte Verifizierung der eigenen Algorithmen.

3D Models with Vertex Color

For scientific purposes we provide some of the data we have scanned using the Minolta VIVID-900 3D scanner and an Isel RF1 rotary stage. The scanned point set surfaces were triangulated using Raindrop Geomagic Studio 5 and 6 and then exported in the OBJ format. The models contain on average 1/4-1/2 million points and 1/2-1 million triangles.

The OBJ data format is an ASCII format that contains a list of vertices (with possibly RGB color values) followed by a list of triangles. A row of the vertex list has the format "x y z r g b", and a row of the triangle list contains the indices to the three corners of each triangle, whose coordinates are stored in the vertex list.
