3D technologies and standards
Today, we see a range of standards emerging that support 3D development.The most
important standards are listed below:
In the near future, we will see more and more 3D experiences of cultural heritage on the
web and on site. For Tony Gill, Programme Officer at the Research Libraries Group,USA,
users and technology are ready for an explosion of 3D:"Most industry pundits agree that
the Web 3D revolution is now long overdue.Typical desktop computers are now sufficiently
powerful to render reasonably detailed 3D models in real time, network bandwidth is
improving all the time, users are increasingly sophisticated and demanding, and there is a
growing standards framework that will support collaborative development. All that is needed
now is the killer app the application that transforms it from an esoteric gimmick into an
indispensable business tool. Perhaps the presentation of cultural information on the web is
that killer app." (Gill, 2001)
A glimpse in the more distant future: Augmented Reality (AR)
Another glimpse into the toolbox of the future is augmented reality which is a marriage
between virtual reality and reality. At the heart of this presentation technology is a pair of
eyeglasses, the AR headset. Developed by Hughes Research Laboratories in the mid-90s,
the headset works with a visual-data display similar to those projected into the helmets of
