When computing, Whatever happens, behave as though you meant it to happen.

When you get to the point where you really understand your computer, it’s probably obsolete.

The first place to look for information is in the section of the manual where you least expect to find it.

When the going gets tough, upgrade.

To err is human….

To blame your computers for your mistakes is even more human. Most of computer problems are computer solutions.

A computer program will always do what you tell it to do, but rarely what you want to do.

VRML

A Historical aspect :

VRML was conceived in the spring of 1994 at the first annual World wide Web conference in Geneva,Switzerland.Tim Berners-Lee & Dave Raggett organized a Birds-of-aFeather ( BOF) session to discuss Virtual reality interfaces to the world wide web.Several BOF attendees described projects already underway to build three dimensional graphical visualization tools to have a common language for specifying 3D world description and WWW hyperlinks, an analog of HTML for virtual reality.Thus the name Virtual Reality Markup Language (VRML) was coined , and the group resolved to begin specification work after the confrence.The word ‘Markup’ was later changed to Modeling to reflect the graphical nature of VRML.

The search for existing technologies turned up several worthwhile candidates.After much deleberation the list came to a consensus: the open Inventor ASCII file format for Silicon Graphics,Inc.The inventor File Format supports complete description of 3D worlds with polygonally rendered objects, lighting, materials, ambient properties and realism effects.A subset of the Inventor File Format, with extensions to support networking, forms the basis of VRML.

Authoring VRML worlds :

The best way to start learning authoring of VRML worlds is to go through the specifications and then there are a lot of tutorilas available on the net to help you write your own VRML worlds.
