Actually, I didn't really care whether it was LOM or not (but thanks for the
information). My real question was whether or not making electronic files of
surface contours from two stereocameras was commonplace. I found this to be
really interesting. Is anyone else doing this? How does the accuracy compare to
other 3D scanning techniques (laser scanners, touch probes, etc.)? How long will
it be until I can go to my local photographer, have two cameras snap a picture
of my ugly mug, and then have some "three dimensional printer" make a life-size
replica of my head to put in the spelling bee hall of fame?

model was made in 4 sections the last of which is being delivered today.
 Each section is about 31"(x) by 20" (y) by 10(z).
You can see more ways of using LOM models for surface visualization at
the UCSD site
look in the earth sciences area.

enjoy !
