   I'm not sure if I understand what's happening with these physhare messages
and maybe I should address this to you alone, but your address is confusing
to me: (phys2shs@uriacc.uri.edu). Is that correct? It looks like the
University of Rhode Island is part of your address? I'm new to physhare.
   Anyway,  I wanted to say something about what you were referring to when
you mentioned staring at images to make them three dimensional. I believe
that there you are talking about two images that are placed side by side,
each image showing a slightly different view of the scene. When you stare at
them, your eyes can be made to look at the left image with the left eye only
and the right image with the right eye only. The two images then merge into
one which is three dimensional. It is just as you would normally view a
scene: your left eye sees a slightly different view than the right eye which
is what gives us a three dimensional view. I think the word "stereoptical' is
related to this phenomenon.
   This is also done with two colored images, one red and one blue, say,
where each image is a slightly different view from the other. Then by using
glasses that have colored filters in place of lenses, one eye automatically
sees the red image alone through the blue lens and the blue image alone
through the red lens.
   My explanation may not be too clear because it is 1:30 AM and I must go to
bed now! Hope you can figure it out.
