Virtual prototyping is a major application of a virtual environment within the product development process. this book explores the concepts, tools, interaction, and simulation used with virtual prototypes and environments. The book contains the selected proceedings of two recent conferences: "Virtual Environments and their Applications", held in Coimbra, Portugal, in October 1994, and "Virtual Prototyping", held in Providence, USA, in September 1994. Both conferences were co-organized by the International Federation for Information Processing. Virtual environments have enormous potential for future applications in industry, and this book should be of interest to all those involved in manufacturing, both manufacturers and suppliers. Vendors for hardware and software, and research institutes and universities dealing with engineering, design, computer science and mathematics, will also find the book of interest.

Die zunehmenden Fähigkeiten von Rechnersystemen ermöglichen den Einsatz komplexer mathematischer Methoden für Anwendungen aus dem Bereich der Graphischen Datenverarbeitung und des Computer Aided Design (CAD). Der effektive Einsatz dieser Methoden in den verschiedenen Darstellungsbereichen der Graphischen Datenverarbeitung, wie CAD-, Animations- oder Visualisierungssystemen, erfordert eine intensive Abstimmung und Zusammenarbeit der Fachgebiete Mathematik und Informatik sowohl in der Forschung als auch in der industriellen Anwendung. Mit der Zielsetzung, einerseits die mathematisch-geometrischen Grundlagen und andererseits die Anwendungen geometrischer Verfahren im Graphik- und CAD-Bereich darzustellen und zu diskutieren, veranstaltete das Darmstädter Zentrum für Graphische Datenverarbeitung (ZGDV) in Zusammenarbeit mit der Fraunhofer-Arbeitsgruppe für Graphische Datenverarbeitung (FhG-AGD) und der Technischen Hochschule Darmstadt vom 28. bis 30. März 1990 den Workshop, aus dem die Beiträge dieses Buches hervorgehen.

This work contains a selection of papers about a broad range of topics relating to CAD modelling and graphics. It also presents an overview of the research and application work done at different R&D institutions in Europe and USA. The papers are grouped into sections. First, issues in feature-based product development (such as representation of form features, consistency management and reasoning) are addressed from different perspectives. Then some design techniques are presented. The following sections deal with communication in design and analysis, input and interaction techniques, and visualization.

Graphics and Modelling are key technologies to support visualisation and product development tasks. Based on the recent developments in the areas of (scientific) visualisation, interaction techniques, distributed systems, and product design, in­ dustrial and applied research have improved the possibilities for further approaches and issues and for exchanging experiences. A workshop on Graphics and Model­ ling in Science & Technology was held in Coimbra, Portugal in June 1994, and the programme committee selected 19 papers for presentation. The workshop had a good international participation. Due to the extensive scientific contacts between Portuguese and German researchers, the workshop included the third Luso-German Computer Graphics Meeting. This book reflects the results of the workshop. The papers were updated after the workshop presentations to reflect the discussions during the meeting. Correspond­ ing to the different topics addresses in the workshop, the book is divided into the following six sections. CAD Models and Architectures Short overviews of the Reference Architecture for CAD and the Integration Con­ cept for CAD applications are given in this section. The integration ability of the international standard STEP is analysed, as well as STEP''s integration approaches for product data sharing and product data exchange.
