Subject: Re: Is there any standard in VR?

Hi Marc,

well, standards are a big problem in the VE/VR field. I know of two efforts on the SW side regarding standardization of interaction techniques and 3D-widgets. One is the work by Pablo Figueroa (more on the VR-interaction side) on a Interaction Techniques Markup Language (InTml, http://www.cs.ualberta.ca/~pfiguero/InTml/). The other are our own efforts on standardization and componentization of 3D-widgets (more on the desktop-VR-side). Infos at www.contigra.com or in the Web3D 2002 publication at http://www-mmt.inf.tu-dresden.de/english/Projekte/CONTIGRA/Dokumentation/Publikationen/.
Have a look at a part of the widget classification and hierarchy under http://www-mmt.inf.tu-dresden.de/english/Projekte/CONTIGRA/Realisierung/Komponentenhierarchie/ (will be updated soon). The behavior of widgets will be delivered together with their geometry and can be parameterized in a high-level manner. Different target formats are possible.
Hope this helps a little.

Kind Regards,

Raimund Dachselt

Hi all, I'm currently looking for the existence of standards in the VE/VR
field. Is there such a thing as a VR standard?

I interested in hardware standards as well as software ones. Specifically,
on the software side, is there any standard yet? Agreed, we have OpenGL, but
this standard is not directly related to VR. I'm talking about higher-level
standards for user interface and user interaction (IT's). Things like
standard 3D UI toolkits libraries for VR.

Any info / remark / thoughts will be greatly appreciated.
