What is VRML?
What is VRML97? and How do I build these worlds?






Are Editors available?

 VRML (pronounced vermyl) is an acronym for "Virtual Reality Modelling Language". VRML is the international standard file format for describing interactive 3D multimedia on the Internet. There are currently three versions. Version 1.0 was created by Silicon Graphics Inc.. Version 2.0, which adds more user interaction, was designed by Silicon Graphics Inc. with contributions from Sony, Mitra, Sun and many others. Two versions were originally considered, one put out by these groups and one put out by Microsoft. After much debate and voting, by the VRML community, the version by Silicon Graphics was adopted as the Standard. Microsoft subsequently issued its version with its ActiveX controls, called ActiveAnimation.

VRML97 replaced VRML 2.0 in December 1997 as the standard. This version is almost identical to version 2.0 except for some minor functional differences and many editorial improvements to the documents.

VRMLscript is just one choice of scripting in VRML. It is very similar to Javascript but is not as versatile. VRMLscript is probably the simplest language available in any VRML browser. Because VRMLScript is a subset of JavaScript, most browsers support it now.

If you don't want to get into the scripting end of VRML, there are some VRML editors available. These include 3D Studio Max by Kinetix, 3D Website builder by Virtus, CosmoWorlds by SGI, Homespace Designer by CosmoSoftware, V-Realm builder by Ligos Technology, ModelShop VR by Mac. users, Platinum VR Creator by Platinum Technology and Trivista 3D Image Cube and CiteMap Builder. These programs are available on the corresponding homesites and the prices range from free trial versions to a few thousand dollars for a full 3D Animation program.

CiteMap trial version is free for download from Trivista and if you want to register it there is a $28 registration fee. This is a useful editor to start with to get an idea of how much fun VRML can be. Many of the high end animation programs like 3D StudioMax can be used to create VRML worlds also.
