Thanks to your comments - and a bit of home work - I solved the street 
problem exposed in the thread above. I kept the single trace test for 
each house but just added a test for those houses bordering the streets 
and adjusting their height to the local street level.

The image below shows the result, with Paolo's (Philippe's) ground 
texture added too.

The code for the urbanism is posted in p.b.s-f of course (version 
2013.03.29)

Better and better.

Now for the wheel tracks in the road,

You are taking requests? Aren't you?  ;-)

I second that--on both counts ;-)  Really nice, Thomas; I feel like I'm standing
in your city. (And it's all so beautifully made that the camera can apparently
be placed anywhere--wow!)

The one thing that stands out to me is that the buildings and roadway are a bit
too *clean*. (Well, very clean!) Some slight discoloration or grunge where the
building walls meet the street would really add a lot to the reality of the
scene--but I honestly don't have any idea how that could be done! It's an
interesting problem...

I'm looking forward to seeing your next image(s).

Well, as you may have seen in the overview scenes of the Gancaloon 
landscape, the roads are /eroded/ into the height_field. In the past, I 
have done wheel tracks in a similar way for several of my scenes.

As you can imagine, the street surfaces will remain in the simple state 
they are in now, as most of the time more detail is not needed. However, 
for close up views I intend to build locally more elaborate street 
surfaces, with cobbles and all, and - of course - wheel tracks.

Not so much /requests/ as /challenges/ ;-) They tickle my imagination...

Thank you indeed. Yes, I am surprised myself at how well the camera can 
take the place of a spectator. It is all turning out better than I had 
expected when I started with this piece of code a couple of weeks ago.

Of course :-)

As far as the street surface is concerned, the solution is easy with a 
more complex texture. For the buildings, if you look up some of my other 
Gancaloon scenes, I have done that kind of texturing, mostly by using 
Sean Day's textures as a basis. They consist of complex layers using 
slope and altitude. At present, the buildings are using a proximity 
macro texture which looks well from some distance but is not too 
convincing at close range. Also, I need to tweak the parameters some 
more to see if I can improve the results. We shall see. There is work to 
do still ;-)

Thanks. They will appear eventually...

A very lonely bird. :-)
The town looks so weird without people. I think that is a complement as 
it looks so real.

The last bird on Earth... Aliens kidnapped all living animals, including 
humans ;-)

Peopling this town is a whole different kettle of fish.

The last man on Earth sat alone in a room. There was a knock on the door...

Indeed. Good luck.
