[PyMOL] rotation about an arbitrary vector?

[Will S. <wh...@br...>]

PyMOL folks,

I've been putting together movies of molecular trajectories on and off
all summer, and have found pymol to be great for this purpose. I now
need to put together something sexy for an end of the summer, and am
trying to make a movie with alot of camera panning. The camera
movement I would like to do is a little more than simple rotations or
spirals, so it would be very helpful to me to be able to rotate about
an arbitrary vector, rather than just the principle axes, in mdo
commands. Is there a way to do this? 

thanks!

-Will

There is. The movie.py script does exactly this: camera movements. 
Basically, any movement can be achieved by adding x,y and z rotations.
You can specify how quick each axis is to be rotated and so on. Any 
camera movement can be smoothed, if You like.

As You wrote You are making movies of trajectories i assume that Your 
animation uses more than one state. Movie.py doesn't get alongt with 
them at the moment. This is because i don't know what would be useful.
If You want to go with movie.py, write me, and we'll get something on that.
