[PyMOL] Displaying vectors each frame

[Thomas A. <ta...@sb...>]

Hi  -

I would like to display some force vectors operating
on atoms. These vectors do have a time dependence.

I know the general mechanism - create a script
which reads the vectors coordinates in and
then draws different 3d vector CGOs each frame.

Has anyone done this before? any code?
Or any pointers on how to load data per frame?
Can it be cached or do I have to load on-the-fly?

Thanks -
Tom
