Hi Tom,
Okay, I thought you wanted to trace out a path through space for the
camera. But for your purpose, it doesn't matter how the things are
defined internally. That's just a matter of representation, which can
be interconverted.
What you really want is to place the center of your active site at the
position of the camera (which has the same effect of doing it the
other way around :p). I'm not sure whether there's a shortcut to it.
But you can do it manually. First center the scene on your active
site, and then move the scene to set the offset from the camera to
zero:
center my_active_site_selection
cmd.move('z',-cmd.get_view()[11])
Hope it helps... and sorry for the confusion :)
Cheers,
Tsjerk
