3-DIMENSIONAL INTERNET DEVELOPMENTS

This paper describes the application of lnternet-based three-dimension al (3-D) user interfaces, comparing them with more traditional two-dim ensional (2-D) interfaces. The modelling of 3-D worlds in the Virtual Reality Modelling Language (VRML) is described, together with an overv iew of VRML and its likely future direction. Multi-user shared environ ments which enable internet risers to meet and communicate with each o ther in cyberspace via avatars (3-D representations of users), are the n introduced. A shared information garden is described which allows pe ople to meet and share information in a dynamic, information-rich, vir tual environment.
