     This summer I ported the QRT raytracer to VAX/VMS systems.  It would
not initially run under VAXC because of a couple of differences in the VAXC
language commands.  It works now however (the redoubtable Marc Barrett tested
it for me).  I also added an include file which allows it to do UNIX style
I/O redirection under VAX/VMS, it's really slick, I wish I could say that
I'd written it.  I sent some mail to Steve Koren about it, he said he hadn't
done any work on it in over a year but that he might pick it up again some
day.  I even uploaded a copy of it to one of the ftp sights, though I don't
remember where right now.
     Marc said that a single frame usually took about three days on his A500
but the same frame only took about twenty to twenty five minutes on a VAX 6620
(depending on the loading), I can vouch for the last benchamrk.  I havn't tried
running it on my A3000 yet.  Mark even produced a little movie with it I think.
The primary reason for the port was just to get the execution speed up.
     I'll go ahead and post it to a bunch of ftp sights and then leave mail
about it when I finish.
