Re: [PyMOL] Coordinates of the mesh-points

[Tsjerk W. <ts...@gm...>]

Hey Björn,

The mesh will be in Pymol camera coordinates, not in PDB coordinates.
You'll have to take the object_matrix (cmd.get_object_matrix) and
apply it to the protein to convert it to the same space if you are to
use it outside of Pymol.

Hope it helps,

Tsjerk
