In this talk, I present our work on virtual reality techniques and the
use of VR, VRML and QTVR in internet applications.

The term virtual reality (VR) describes acceptable substitutes for real objects
or environments. VRML (the Virtual Reality Modeling Language) has emerged as
the de facto standard for describing 3-D shapes and scenery on the World Wide
Web. The VRML technology has very broad applicability, including web-based
entertainment, distributed visualization, 3-D user interfaces to remote web
resources, 3-D collaborative environments, interactive simulations for
education, virtual museums, virtual retail spaces, and more. VRML is a key
technology shaping the future of the web.

QTVR (QuickTimeVR) creates an immersive, photo realistic experience simulating
actual or imagined three-dimensional objects and places based on images. We
used a combination of VRML and QTVR to generate VR-Applications quickly and
easily. Simplified models are generated in a region-based manner, which enables
interactions in each region and with adjacent regions. The talk includes VRML
and QTVR examples and information on how to develop these applications.
