I am really fascinated about the active and dedicated help, thanks to both of
you!

Somehow I really missed the in-text links to the POV-ray code. I will need to
carefully search if I can derive a solution for my objective from these...

But please do not neglect your tire (are you talking of a car tire?), this would
seriously disturb my peace of conscience :)

It's sad that I cannot attach an image, so I'll try to explain a bit more: The
field data is in a volume composed of a hexahedron and a cylinder (so it is more
complicated than in a box). It is computed for a unit cell with with hexagonal
base area, which I'd like to tile for some periods in x- and y-direction. So I
thought the easiest way would be to have basically two loops: one over the
points (x,y,z,color,brightness) inside the unit cell; and another one over the
lattice, which basically repeats the first stepp over and over with translated
coordinates.

Wouldn't it be possible to generate the field profile in the first loop using
"boxes" of emissive media (properties set according to x,y,z,color, ...), i.e.
3d pixels that in total fill up the mentioned volume?

For the emitters mentioned at the beginning, I could image that a more simple
"glowing" effect (i.e. a small sphere with a halo) would be sufficient. In the
ideal case the glowing would be adjusted depending on the location in the field
above.

I hope this was somehow more clear than the short paragraph given above. I am
deeply grateful for any further suggestions and code samples!
