The same way antialiasing works. Shoot at the
four edges and find a great difference in color.

I for one first thought that someone was explaining
mosaic preview, then I saw that it was Rune who
wrote, then I read on.

I find the idea rather attractive, and I'd guess that
anyone able to look at the source-code and understand
antialiasing could tweak that to do the super-pixeling
Rune has proposed, though I'm not expert and could
be wrong there.

I always liked Mosaic-Previews, but Rune's idea
is even better. After all, you do several passes with
POV-Ray until you've set up camera, lighting etc,
during that time one could easily adjust the superpixeling
to the needs of that render, and later on, save time
by just copy-paste.

If there's someone out there capable of doing that in
a clean and efficient way, we might go rebel against
the POV-Team and have them introduce it into the
official version very quickly! ;-)
I rather like using the Official Version, and have only
used MegaPOV once to experiment a little with
isosurfaces and photons, when I knew that POV 3.5
would get them, just as background why I'd go rebel... :-)

Tim
