Introduction to VRML
3D modelling and Virtual Reality is a recent newcomer to the web. There are a number of technologies associated
with Virtual Reality, from fully immersive environments to three dimensional representations on a standard monitor.
For the Past Perfect website we built some models in VRML.
The Virtual Reality Modelling Language (VRML, sometimes curiously pronounced 'vermal') is an open standard
language that allows the viewing of 3D 'worlds' over the web. Viewing VRML files require a special plug-in,
called a 'VRML browser". Most browsers, once correctly configured, will automatically open and display VRML files.
With a VRML browser users can explore worlds interactively: zooming in and out, moving around and
interacting to a limited extent with the virtual 3D environment.
VRML has its origin in Silicon Graphics Inc.'s (SGI) Open Inventor 3D graphics programming language, and
was first published as VRML in May 1995. By August 1996 many improvements were incorporated into the new,
VRML 2.0 standard. Subsequently VRML 2.0 was renamed VRML 97 and formally accepted as an ISO standard in
December 1997.
