Fine. It looks like that's going to essentially be my next project here at
work and I'm trying to figure out the best platform to work with. I ahve
access to basically every UNIX platform (alpha, decstation, AIX, Sun, SGI)
as well as the Mac. I am going to buy a Pentium-90 (despite being slower
than a PPC) soon so I can run WinNT stuff on it. What I really need info
on at this point is where VRML is going (BTW, I've been reading every
article on this list since its inception) in terms of development and if
there's any reasonable way I can evaluate my 3d development needs to bring
the implementation of my ideas into alignment with the future directions of
VRML. I would like to ship myself off to WWW94, but they've suspended
registration so I will have to rely on the reports from the Labyrinth Group
and others, but I believe our showing there will in large part determine
where we're going. If I need to buy a RealityEngine to do this project I
probably will, I just thought it would be nice to make it VRML compat as
