To the software designers

[Steve Franklin <franklin at ug.cs.dal.ca>]

First and foremost, I would like to thank the authors of Geomview for a
fantastic product which is giving us much satisfaction here at the
biophysical department of Dalhousie University, Nova Scotia. We are coupling
its capabilities with the tesselation routines of NUAGES, giving us
excellent 3-d visualization of internal organs of the upper torso. 
  Our research requires this to help us understand and analyze cardiac
defects and complications through body surface potential mapping (BSPM).
Your package permits us to view the results of our 3-d digitization very
nicely. 
   The one question I had was: is it possible to vary the transparency of an
object? You see, ideally we would like to digitize the lungs, heart, and
torso wall, and display all three simultaneously. Obviously, the torso wall
would have to be somewhat transparent so that we could see the internal
organs. Is this possible? Will I be running into complications when I start
dealing with several objects in one Camera window? I already notice that
things are a bit slow when I deal with a 200K *.off file. 

Looking forward to hearing from you,
