Very true.
It would be great to have a feature where we have access to a camera
object, with control of the:
1. camera root (where the camera)
I experimented with this method a decade ago when I was working
on a stereo 16mm film for the late Kent Wilson. The parallel
line-of-sight method was described in a popular book on stereo methods
.. sorry I don't remember the reference and it would take a lot of
digging to find it.
To be honest,
Very true.
It would be great to have a feature where we have access to a camera
object, with control of the:
1. camera root (where the camera)
2. camera target (where it's looking)
3. focal length control
4. and all associated 6D transforms.

You're both right.
"Perfect" ray-traced stereo pictures are impossible in PyMOL
because the built-in ray tracer is limited to an orthographic
projection. Unfortunately, I optimized all the vector code for this, so
we're talking a major rewrite to change that : (.

This method of generating stereo images is correct, but also leads to
quite a bit of vertical parallax (the so-called "toe-in" projection) -
this is why many stereoscopic images are ha
Flip,
Thanks for answering that question -- actually, the new PyMOL release
(version 0.88, downloadable from http://pymol.sf.net ) makes this a
little easier.
ray angle=-3

ray angle=3

This is superior to using the "turn" command because it also rotates the
