VRML

Stands for "Virtual Reality Modeling Language." If you think this has something to do with HTML, you're right. While HTML is the format for Web page production, VRML is a 3D navigation specification, which enables the creation of interactive 3D Web sites. With VRML, visitors can take virtual tours through buildings and view three-dimensional models of cars directly from their Web browsers. Though the technology was created by Silicon Graphics and Intervista Software a number of years ago, it still is not widely used.
