A note, vrml is really a 3D specification language with URLs thrown in.
It doesn't have much to do with VR. In fact, people who do real
VR with Silicon Graphics machines don't usually use Open Inventor, they
use Performer --- another SGI product designed for speed -- or roll their own So why don't
we quit pretending that VRML really says anything about immersion,
admit that what it really describes is 3D graphics, and name the
thing appropriately? wrl is fine.
