I just *had* to try to make my own greeble-macro :)

here's a first result, rendertime: 3'48" on a Sempron 2400+ with 768MB RAM, 
running Windows XP SP2

comments are more than welcome !

I think it is a bit of a stylistic departure from the usual but the 
result is attractive, even gorgeous, and useful I think.

The obvious problem with this and the other attempts at an automated 
generator is the lack of averarching elements that would span "cells" 
Simply varying the scale of the cells does not get that effect.

Hmmm...

It is looking gorgeous, for my eyes! It is a good combination of greebles 
and metallic texture.
I also like that cell structure which reminds me for a large town full of 
huge buildings. Here, in this case, it ensures that the shown ship section 
indicates its huge size. Your design is actually better than my greebles I 
use for the Imperial Carrier SENECA. Actually, I would like to climb my 
X-Wing, and dive down into these artificial ravines hunting some imperial 
fighters..!

An additional idea: add a few very fine (very thin) antennas randomly, maybe 
with having a few anti-collision lights on them (no light but ambient 1.0). 
Probably, the tiny antennas would be recognizable from this distance.

Another idea: Build a macro which can be applied to cylindrical objects, 
which will have a fluid move from surface structures (as seen here) to side 
structures and (maybe) bottom structures. Wow!

Last idea: The borders of these ravines shouldn't be too straight like cut 
by a knife - let these ravines have slightly different diameters (just 
slightly, not more).

This here seems to be a surface macro. I would be veeery interested now to 
see a side macro (different shapes and structure) and a front macro (again 
different structures, I guess, and kind of symetrical).

Again: it looks damn good! This macro will become the stuff many of us will 
want for our future armadas of starships!!!

Greetings,

Sven

Nice, I like it! Never mind the fact that i didn't know what a greeble was
and had to google it to find out!! Are they difficult to do?

true, but I'll try to work on that :)

depends on how detailed it needs to be.  For long shots, my macros might 
be good enough, but in close-up they'll look kind of lame :)

hehe :)
I was just trying to create a city-macro based on this greeble-macro :)

good idea! I'll try that !

sounds difficult, but not impossible :)

well, for the city-macro I just made, I made it possible to have streets 
between the buildings (kind of obvious, no? :)), so it shouldn't be any 
problem to do that also with the greeble-macro :)

first I'll try to finish this, with more interesting greeble-objects 
than just superellipsoids
then I'm going to try to make a triangular version of this macro... 
don't know how exactly yet though :-/
after that's done, I'll try to make that side- (with windows), front- 
(maybe with extra weapons?), back- (possibly with engines?), ... -macros 
:)

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:
