Hi Timo,
I think you may have to switch to a different drawing primitive like TRIANGLES
or TRIANGLE_STRIP. Since these are closed objects I assume that the enclosing
area should be fillable with a color of choice. Unfortunately I have not
actually had a chance to play with these primitives, so I can't provide any
docs. Check out \PyMOL\PyMOL\examples\devel\cgo08.py and/or cgo07.py for
examples of TRIANGLE_STRIPS.

Subject: Re: [PyMOL] Creating coloured and transparent polyhedra
Hi PyMOL users,
thank you for your help. I tried to apply Carsten's suggestions using the
LINE_STRIP approach. This is what I tested:
from pymol.cgo import * # get constants
from pymol import cmd
obj = [
LINEWIDTH, 50,
BEGIN, LINE_STRIP,
COLOR, 255, 0, 0,
VERTEX, 11.335700035095215, 7.798659801483154, 7.798659801483154,
VERTEX, 11.335700035095215, 5.352089881896973, 5.352089881896973,
VERTEX, 14.965800285339355, 5.352089881896973, 5.352089881896973,
VERTEX, 14.965800285339355, 7.798659801483154, 7.798659801483154,
VERTEX, 11.335700035095215, 7.798659801483154, 7.798659801483154,
END
]
cmd.load_cgo(obj,'cgo01')
where four atoms make up a square. This snippet creates - when called by "run
<path-to-script>" - four lines between these coordinates I got by using "print
cmd.get_model('<selection-name>', 1).get_coord_list()". How can I have the the
area between those four points filled with a colour of my choice and have it be
partly transparent? The next step would be to create polyhedra with
corresponding surfaces with atoms spanning a three dimensional object.
Thanks in advance
Timo
