P3D Stereo Window Demonstration

> > Actually, a simple rule is "mask the outside edges.

By masking the left outer edge, you end up seeing less from the
left side.  Everything ties together.

The interesting part is that the metrics of the stereo window
are such that you don't need to visualize the image in 3d in
order to place the window in the right place.  This means that a
computer could do it via a simple algorithm.  Of course, the
impact of this adjustment means is understood only under
stereoscopic examination.  That's why it is difficult to explain
this concept to beginners with words and without the benefit of
a real stereo picture.

For our next club meeting I am scheduled for a demonstration of
the stereo window.  I plan to cut open the top of an RBT mount
and shift the rails while the slide is sitting inside my
Brackett Dissolver stereo projector.  This will be a live
demonstration of the stereo window.  The advantage of using the
Brackett Dissolver over the TDC is that you can access the mount
from the top while it is being projected with the BD, while you
cannot do it with the TDC.

If this works out I will bring it with me to Mesa AZ and perhaps
use it with DrDave's and Jon Golden's workshop on stereo
mounting.
