Try UVPOV, http://nathan.kopp.com/patched.htm , or the superpatch
(currently offline.)

You might look at the trace() function in the superpatch.  It was
designed to do this and more.  Unfortunately, the superpatch is
offline at the moment, but it will go back online within the next
day or so; watch for an announcement.

Cool.  If the acronym means what I think it does, it's exactly what
I want.

Many thanks.

Thanks -- of course, the only thing I had to do with it apart from
(not) sitting still was to reduce it to something you could download
in your lifetime.  Flamingo Optimizer and Chisel can both decimate
a VRML mesh with texture coordinates without screwing up the
image-to-mesh mapping, which I think is magic.  I can't conceive of
trying to write and debug that code.

No, it was a problem we both share.  An old friend I hadn't seen in
a while came by and said "Hi, Bob", so naturally I had to take a
drink.  ;-)

The lasers were tripod mounted and they even did an automatic scan
which took about a minute.  He took three scans and three photos
and then imported them into MAX and played with them for about a
minute to join them.  Sorry that I've forgotten who made the
cameras and software, but I'll bet there's a dozen of them at this
year's SIGGRAPH.  Beats the hell out of that little finger thingy
that does sort of reverse STL to scan models in.
