Dear Tom,
If I'm not mistaken, it is always the camera that is moving when you rotate
a molecule. That is how Pymol is so fast - only one point is actually
moving.
Have you investigated the mset command to set waypoints for the camera?
http://pymolwiki.org/index.php/Mset
http://pymolwiki.org/index.php/MovieSchool_2
After you set a number of waypoints you can play the animation and PyMol
interpolates camera positions between your waypoints. I would suggest you
keep a text file (or .pml script) open when you work with mset so that you
can keep a record of all of your waypoints (use get_view) and what they
correspond to.
You might have better luck working with surfaces if you want to export a
protein into a 3D modeller. I have done some work with meshlab where I
import .x3d files corresponding to the mesh vertices from electron density
contours.
Good luck! I'd love to hear the solution you decide on.
Mike
