The effect of zooming in stereo panoramas.
- I have solved, to my own satisfaction at any rate, the way zooming
works in stereo panoramas.
Apparently, zooming in reduces the angle of view and therefore
multiplies the effective lens separation by the same amount, so
that when you zoom in upon distant objects, the stereo separation
between them is enhanced, and you get (as I have written elsewhere)
the impression that you are actually moving closer to the objects
in view rather than just enlarging a picture of them. For me, this
is a significant enhancement of the "reality" part of Virtual
The only problem is that as you pan past objects much closer at
hand, the parallax between them is exaggerated to more than the
eyes can accommodate, and produces a rather uncomfortable
I suspect this may encourage people to restrict the ability to
zoom in, so that viewers are protected from this discomfort.
Personally I would prefer to be able to zoom in to more distant
objects and blink when nearer objects pan past. <grin>
