Creating a polyhedron inside a stack

Gabriel Landini
Hi,
I wonder if anybody has any idea about creating a binary polyhedron inside a
stack (either filled or hollow).
More precisely I would like to create a truncated octahedron
(tetrakaidecahedron or Kelvin cell) like this one:

If somebody has some insight on this, I would be very grateful.

Cheers,

Gabriel

Hi, Gabriel
I have only a structuring element for a cubeoctahedron:
ste=[[[0b,1b,0b],[1b,1b,1b],[0b,1b,0b]],
         [[1b,1b,1b],[1b,1b,1b],[1b,1b,1b]],
         [[0b,1b,0b],[1b,1b,1b],[0b,1b,0b]]]
This dilates (in 3d square grid) a point to a cubeoctahedron : example  
rejected
Example with 40 repetitions
I don't know how to create in the existing 3d morphology plugins a  
structuring element.
Regards
Karsten

Thank you Karsten. In the mean time I found that the body cubic lattice gives
a tessellation of space with truncated octahedra. (so this is the seeds in
each corner of a cube and one in the centre). I will try Thomas' 3D distance
map to see if I can get it with that.
Thanks again.

Regards,

Gabriel
