I was going to suggest object pigment(s) until I tried it and failed the
attempt.  :)
Here's what I finally did instead. Needs rescaling to be correct measurements
for a real field. I didn't consider thickness either, just wanted all parts to
show. Originally was making a pigment pattern for a flat plane anyhow. I haven't
used POV for that purpose in uncounted years, maybe somebody else has answers.
Also, you would want to think about how to go about doing real
dimensions/measurements. I chose not to use actual numbers of feet/meters for
this, only going for a likeness of the drawing you gave, otherwise I might have
done this minus the 45 degree angle first so as to have axial distances then
afterward rotate the field (if you understand my meaning).
