This brings up an important issue. The pleasure of visiting a VRML world
is going to be greatly influenced by the quality of the models to be
viewed. The Lightscape models are the worst case. This is no fault of
Lightscape - their software is fantastic at producing Radiosity solved
scenes. But the result is organized poorly for the purposes of VRML.
Tools need to be made available to ease the task of reorganizing scenes
for maximum performance.

The SGI Booth that we ship with WebSpace is pretty bad, too. We need to
work on that. But I have seen some scenes that are designed very well.
The NIST stuff I just saw today runs at full frame rate on my admittedly
fast machine. But it's so fast that I'm sure it will be reasonable on a
slower machine. But even those scenes still need work. They need LOD and
inlines, etc.
