For my own city buildings, I'm making some more semi-detailed 'rooftop junk'.
These are two 'air-conditioner units' so far. Not really meant to be seen
close-up, and they will be duplicated lots of times.

They actually might be *too* detailed-- that is, requiring more scene memory
than is worthwhile, for such a relatively small visual greeble. I'll tackle that
problem later ;-)

The only problem I ran into was with the shiny metal pipes-- their 'corrugated'
look is just a normals pattern applied to a section of a torus object. But I'm
still working out the best SDL approach of *applying* those normals-- what kind
of 'mapping' to use and what kind of bump-map gradient pattern. So far, I
haven't gotten the normals to work consistently around an *entire* torus object
(as relates to a particular light source location.) On half of the torus, they
look correct; on the other half, their effect is 'reversed.' It's probably due
to my choice of mapping etc...

Greebles? That reminds me fore the amazing work Zeger Knaepen did, years
ago, for us POV-Ray users. But his greebles were for SciFi projects.

If you want, search for his amazing work here in the groups.

That was, however, some days ago. I think, in 2008... :-)
