The streets need of course a good scrubbing ;-)
The most simple, like presently, is based on the height_field texture.
That needs an overhaul. However, especially for close ups, a street
surface is needed. That is going to be a different matter and shall be
built locally when needed.

I thought a simple texture based on the use of warp like the example
posted by Philippe some time ago (tex_Sol_en_galets).
;-)

I am not sure I remember that one. Still, it is the texture of the
complete height_field which shows through, so there would be need of a
partial reworking.

Sorry, I don't remember the news, but the code posted by Philippe
(2007-05-09) was very useful to me to understand the use of warp in
textures.
It's a silly idea use a duplicate of the height_field clipped by the
contour of the old city and translated a bit vertically?

Thank you very much indeed, Paolo. I am a voracious collector of code.
;-) Always useful one day or another.

No, it is one of the possible techniques. I had not yet seriously
thought about that use, I confess, and I shall give it a try. Should
give good results for the fairly flat areas and the overviews.

By the way, do you remember which 'Philippe' this was? Philippe Gibone?
Philippe Dubar? Strangely, the search in povray.org does not turn up the
thread.

When I take snippets of code, I write as a comment the name of the
author and probabily the message was signed only with the first name.
Maybe the post wasn't on news.povray.org but on news.zoo-logique.org,
who imho isn't fully indexed by search engines...
I'll bet on Philippe Debar.

It looks remarkably like Scarborough (North Bay)

Indeed. I think Scarborough was copied on Gancaloon ;-)
