It's looking better and better <*sigh*> You've also solved the need for
'recessed' building sections on top of the 'main' buildings. I still haven't
tackled that (well, with my newer 'buildings as height_field faces' scheme,
anyway.)
Your approach is well worth the effort!

Well, I know Amsterdam has one at least. ;-)

Do you mean the 'compound' buildings with the decreasing sizes? Those are
basically a specialised building type that just creates two or three
sub-buildings with different versions of the base polygon. Since the building
construction already offsets polygons extensively, it wasn't a lot of work to
add this.

So far so good. But I think your buildings are much more detailed and realistic
on an individual basis, which I'm going to struggle with later on. It's
interesting to compare approaches on similar but unrelated projects - there are
indeed many ways to skin a cat!

Ouch! I hope no cats have been hurt in this project! ;-)

I can confirm that no cats were hurt during the development of this project, and
that all skinning incidents have been metaphorical in nature :)

The one that have the official title is in Bruxel, on the Grand Place.
As it's a private house, there are no visiting.

This as far as I got with my original code (and I made only a single small
render, unfortunately.) The upper building sections are not 'correct' though.
Then I changed the code, to try a different approach to those upper sections.
*Then* I decided to go in a different direction entirely-- making the building
faces as height_fields (which will require a re-work of my original
city-building code.)
Ah, the fun of it!

Pleased that you are enjoying yourself.
This is looking too good. ;-)

Yes, I remember this image - really nice. I need more roof furniture!

It's not the destination, it's the journey :)
