Hi Robert,
PyMOL>help rotate
DESCRIPTION
"rotate" can be used to rotate the atomic coordinates of a
molecular object. Behavior differs depending on whether or not the
"object" parameter is specified.
<snip>
So much for rotate. The help for turn is misleading:
PyMOL>help turn
DESCRIPTION
"turn" rotates the camera about one of the three primary axes,
centered at the origin.
<snip>
It does not turn the camera, actually. It changes the orientation of
the scene with respect to the camera. The effect is the same, and you
can interconvert. That is the basis for the povray macros I wrote some
while ago to combine things in object space with those in the pymol
camera space in the exported scene.
Cheers,
Tsjerk
