Well a persons eyes are just along side each other so it's really just a
horizontal shift.  Not much either unless the scene is intended to be very
close.  Of course if not sticking to realism entirely then you could still have
a large shift.  I've taken photos that way in order to see large scale objects
in 3D.
I've also just rotated the camera around the y axis a bit without even using a
translate for 'location' or 'look_at' and it doesn't seem to make too great a
difference.  If only approximation to a stereo image is all you want then that
could be okay but you'd probably need the look_at point set out beyond the
central focus of your scene.

| Hi,
| is it possible to shift the Camera horenzotally  (incl. look at point)
| from the current point of view, in order to render two pics (one for the

| position 3-dimensionally?
