This two pictures are the last of the patterns in my tiling patch.
Yep... It's a code patch, not a script.
Available soon on http://pov.grimbert.cjb.net/
I'm not happy at all with the naming used, but I have no time
to find good names... I'm still hooked on the 2D paving of the plane,
specially with n connected square/hexagon/triangle pieces.
The good news is that, at least for that kind of paving, I have found
a naming scheme.
In the meantime, maybe someone will find a macro/script to provide the
same kind of paving, but I doubt it...

Alas no 3.4.3.3.4, nor its dual the `Cairo' tessellation.

the 3.4.3.3.4 is still on the design table, I just need more time...
as well as the two 6.3.3.3.3 versions, and 12.6.4 and 12.12.3
The "cairo"* is also part of the new patterns I have found, thanks to
Vahur Krouverk and a little web surfing. I did not realise it was the dual
of the 3.4.3.3.4 . I wonder if any of the other archimedians have duals, and
what they would look like... Thanks :-> I already had so little time, now I
have a new branch to explore !

are you talking about universal macro generating pigment form count of
segment/vertex/figures or script for selected patterns ?
here is my result for your first pigment
script is not optimized, I want to show way of finding
of course MegaPOV required

Why "of course"? Here are a few that work in plain ol' POV. I started

"of course" because of keyword function{} and becouse "version unofficial
megapov .6;"
I was sure that it is possible

Actually, there are bugs in some of them, particularly the 6.4.3.4
implementation (starting with its name, but the tiling is a little off
too.) Also, I've rewritten them to work with nongradient pigments as
arguments and completed the set (well, almost completed the set... I
still lack the two versions of 6.3.3.3.3)
If anyone finds this even vaguely interesting, I'd be happy to post the
whole set to a scene-files newsgroup.

One last update... I now have both versions of 6.3.3.3.3 as well.
