Virtual reality can be divided into:
The simulation of a real environment for training and education.
The development of an imagined environment for a game or interactive story.

35. VRML ( Virtual Reality Modeling Language )
Standard language for interactive simulation within the World Wide Web.
Allows to create "virtual worlds" networked via the Internet and hyperlinked with the World Wide Web.
Aspects of virtual world display, interaction and internetworking can be specified using VRML without being dependent on special gear like HMD (Head Mounted Display).
VR models can be viewed by Netscape, IE or with any browser.

36. The stages of the Multimedia project
