You do, at least in a way. It's called... view=cmd.get_view() and cmd.set_view(view)
... Adapted from kristian's wonderful tips page: http://www.rubor.de/bioinf/pymol_tips.html Meaning of the get_view output Of the 18 numbers in the output array, 0-8 is the 3x3 rotation matrix, 9-11 is the camera offset, (RELATIVE TO ORIGIN, in WORLD FRAME OF REF.) 12-14 is the origin of rotation, 15-16 are the clipping distances, and 17 is the orthoscopic flag. For example, view=cmd.get_view() view=view[0:12] + (1,3,4) + view[15:] cmd.set_view(view) would set the origin to (1,3,4) Cheers, Warren -- mailto:[email protected] Warren L.

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. :) JP ---------- Forwarded message ---------- Date: Wed, 4 Jun 2003 13:51:16 -0400 (EDT) From: Tim F <[email protected]> To: Warren L.

What you really want is a non-symmetric camera frustrum (dunno how hard this is to do in pymol....) where the two images should look along parallel vectors separated by some distance (something like 1/20 the focal length). Check out Paul Bourke's page for all the details: http://astronomy.swin.edu.au/~pbourke/stereographics/ Hope this helps.
