[photo-3d] 3D vision

[ka2hsu@xxxxxxxx]

Help wanted!

I need advice on how to build a viewer to enable my adult daughter to see
objects in three dimensions. She has never been able to see normally in
three dimensions, having been born with muscle adhesions on one eyeball. 
Several operations were performed to provide cosmetic correction.
However, she has never been able to obtain enough muscular control of the
affected eyeball to enable her to bring her eyes to focus simultaneously
on an object. At this stage of the medical art, nothing can be done to
correct this imbalance. Her normal, dominant, eye is correctable to 20/20
with glasses and her non-used eye has 20/20 vision without correction. I
have almost 50 years of  Realist photos that for which she has never
experienced the 3D value.

Her three dimensional sense is created when she moves her head from side
to side and views the relative motion of objects at different distances
in space. Since subscribing to this list only a few months ago, I have
become aware that single lens 3D photography is based on somewhat this
same principle. It has occurred to me that I could bring her into the
wonderful world of 3D viewing of photographs if I could create a viewer
which has separate but fully maneuverable optical paths to stereo pairs
and projections. 

This is probably not of general interest so please contact me off-list if
you can help with this special problem. A concerned father would be most
grateful.
