This workshop on Graphics Modeling and Visualization in Scientific, Engineering and Technical Applications was held in Darmstadt, Germany, on 13-14 April 1992. Visualization is known as the key technology to control massive data sets and to achieve insight into these tera bytes of data. Graphics Modeling is the enabling technology for advanced interaction. This book contains the keynote papers from three internationally well-known invited speakers and a selection of papers submitted to this workshop. Due to the effective scientific contacts between German and Portuguese researchers, and the results from this cooperation, the workshop was also the 2nd Luso-German Meet- ing on Computer Graphics. The keynote papers present an excellent overview of the main topics of the workshop. Prof. Rae Earnshaw focuses on Scientific Visualization as an inter- disciplinary area of research and application, presenting state of the art concepts and works currently being developed, and the requirements of visualization sys- tems in the 90's. Prof. Frank-Lothar Krause presents Product Modeling as the key for information integration in industry, in particular to support CAD-CAM inte- gration and CIM. Dr. Rolf Iindner introduces the DEDICATED (DEvelopment of a new DImension in Computer Assisted Teaching and EDucation) project, a European DELTA project with a strong involvement of German and Portuguese partners.
