[chimera-dev] Rotating about an axis with mouse

[ladam]

Hi all,
I have a python script that allows me to rotate a residue in a molecule
of a desired angle around a predefined vector.
Now I'd like to be able to do this graphically with the mouse on a selected
residue.
I have almost found what I want if I use the 'Move selection' option in the
'Movement Mouse mode' but this does rotate around the center of Mass or
geometric center, not around a vector.

What I plan to do is derive the code from the corresponding 
/share/MoveSelection/move.py
module and try to insert a vector instead of the 
center_of_rotation(self.movable_groups)
  but there is maybe a better, simpler idea.

Any suggestion?

Thanks a lot
