Opis

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."
