I second Al's opinion. The consensus in research and popular journal
publications, even among the hyped-up media, is that a 'Virtual Reality
application' MUST include Interaction, and in it's 'true' form also
should include Immersion, though there are many commercial,
non-immersive, desktop VR software systems. That doesn't require
high-end SGI's to qualify, either. Even the lowest-end, inexpensive
desktop VR systems capable of running on a bare bones Windows 386 PC
system support some form of interaction. The VRML proprosal is, in my
opinion, essentially an Open Inventor Viewer with extensions to handle
WWW hypertext-like links -- nothing much VRish about that since it
supports neither interaction nor immersion. I think in choosing the
file naming extension, the emphasis should be focused more on 3D and on
markup language (ml) to be consistent with common usage among WWW
terminology. Also, since HTML file names aren't restricted by DOS's 3
character file extension limit, why should VRML (which should probably
be renamed to remove the VR)? I think .3dml would be more appropriate.
