This is the kind of greeble I like very much: not too intrusive, but subtly
guiding the eyes over the surface. Good work Zeger! Could be used
architecturally, on a curtain wall.

I went the other way. I based my Greeble code on the macro that I used
to generate this city:

Be careful, Borg! We otherwise will get support from our captain who will
come back to us from the near future! With nano viruses which will destroy
you Borg from within, as soon as you assimilate!

Hi!
Will it be able to use different textures for vertical and for surface
areas? That would allow the usage of windows for all side areas of your very
useful and breathtaking macro! Best would be, one texture for front and
back, one for left and right, and one for surface (and bottom).
Respect,
Sven

as it is now, the texture has nothing to do with the macro, the macro
only handles the geometry, so yes, you can define different textures for
any part :)
btw, has anyone got any idea on how to subdivide a triangle to make the
"greeble-cells" ? :-/

This one's actually quite good. A nice metallic texture, instead of
polished marble.

One way is to give cells borders, and require that two cell types cannot
meet unless their typing along that border matches. Then you can
sprinkle some stand-alone cells in with larger pieces, and even
irregular pieces. The tricky part is to make sure that the surface can
be completely tiled in this way.
Or you can have multiple layers of greebling, in which the higher level
has tubes and stuff that traverse the lower-level tiles.
Regards,
John

Depends on the proportions of the triangle. An equilateral is best
subdivided into smaller equilaterals. A triangle with the golden ratio
between its sides is best divided with a Penrose tiling.
