print clipped(3lzt) should print the indices of atoms that are
clipped off by the clipping planes. That works for me, but in
Hi Johannes,
Coincidentally, I found myself in need of the same functionality the
other day. I came up with this:
from pymol import cmd
def clipped_by(at,v):
x,y,z = at.coord
nz = v[2]*(x-v[12])+v[5]*(y-v[13])+v[8]*(z-v[14])-v[11]
return nz v[15] and nz v[16]

Hi Johannes,
My guess is that you missed that get_view[0:8] is a _column-major_
rotation matrix. Transpose it before using it.
I decided to take a look at this problem for preparation of better
clipping planes in PyMOL. I got it to work in PyMOL using Python,
after much fussing about.
Here's

from PyMOL and write scripts against that yourself to determine atom
inclusion. See get_view (http://www.pymolwiki.org/index.php/Get_View)
for more help.
Hi Jason,
thank you again for the hint.
Hi Johannes,
It's not that hard. The clipping planes are defined by the z coordinate (in
the viewing matrix). So you can get the atoms for a selection, transform to
get the new z coordinate only, and check whether it's in between the planes:
m = cmd.get_model(selection).atom
v = cmd.get_view()
m

Hi Johannes,
PyMOL's awareness of and capabilities surrounding clipping planes does
not allow this functionality. Improving clipping planes is a higher
priority, so I hope to have this updated in the near future.
