• stable hardware and reasonably priced software that resulted in more and more powerful and successful VR demonstrations and industrial applications;
• stable graphics application programming interfaces (APIs) such as OpenGL and Performer;
• continuously increasing performance, allowing larger data sets to process in real time and with improved visual quality; and
• curious researchers exploring for industrial applicability.
Martin Goebel is head of the Virtual Environments research division in the Institute for Media Communication of the German National Research Center for Information Technology (GMD). His research interests include augmented reality, virtual reality, scientific visualization, and real-time simulation. He has initiated and chaired several Eurographics workshops on virtual environments from 1993 to 1998 and was program co-chair of the Eurographics 95 and 98 conferences and of the IEEE VR 2001 and 2002 conferences. He received his PhD (Dr.-Ing.) in 1990 from Darmstadt University. He is a member of the IEEE Computer Society, the Eurographics Association, and the German Computer Society (GI).
