Thanks. The texture is actually individual rounded boxes arrayed in
concentric circles. Each takes its color from an underlying photo using
trace(). So it is a kind of fake mosaic. To automate a more realistic
mosaic, where the pieces loosely follow contours, would be an
interesting accomplishment, but not within my reach I am afraid. The
photos are by a contributor I know over on DeviantArt. The pinkish ones
are of her own lips, closeup.

Yes, furniture always gives me problems, especially with proportions.
Wrought iron I think can be very strong, but this may be a bit spindley.
Maybe Wire this thin might be used double or more on the legs. Also
this furniture is probably still quite high vs its footprint. Believe
it or not, I already took the original models and reduced the vertical
scale by 1/3. Here I think I both wanted to show off the table tops and
the bricks so I probably tended towards tall and spindley. I can never
quite believe chair seats are only up to my knee. And I agree these
chairs are more like stools, not really suited to a wide bottom. Maybe
I picture this place with slender young women nibbling on silly little
sandwiches.

Yeah I'll fix the posts. The arbor structure was a single modelled
piece with one wood texture applied. The center of the circular wood
texture (rotated to vertical) is about at the right foreground table.
I'll take a breath then make the posts separate with separately applied
textures. I was just being lazy there, though I might get away sith it.
What *was* I thinking?

Never thought of that, a nice compliment. I love those impressionist
paintings.

Yes I agree, That welded iron stuff really is remarkably strong.

Yeah, me too, actually I was puzzled as to how this would actually be
constructed. Examples I see with google do often have a little
finishing around the foot though. Probably to cover any bolts or other
fastenings to the masonry base.

Yes, I will play with that somemore.

Yes now that much is set I can afford some overnight renders and try and
improve the richness with the radiosity. Thanks for suggesting that.
The sun value is determined by LightSys. But its *apparent* brightness
has a lot to do with the sharpness of the shadows. With no area light
to area light with a spread of 1% the distance, the shadows look sharp
and deep and the sun bright. In this image the spread of the area light
is 2.5% of the distance to the light. At 10% the distance this image
looks quite dull like it is a cloudy day.

This is an interesting technique indeed... Hmm, have to think about that!

Comparing those photographs with your furniture, I believe yours are just a
tiny bit thinner, especially the tables. Note that several chairs have
double wires too. I remember those chairs from my youth in France, where we
had them in the garden. However, I agree with you and Alain that the
material is quite strong by itself, so my comment on this is not entirely
valid. It is more the impression of frailty that concerned me I think.

After reading Alain's answer, I agree that the posts can rest on the
pavement, perhaps fixed invisibly by a steel pin. So, no real need to change
that. Now that I think about it, I have seen posts like these, fixed a short
distance above ground (by a metal pin) giving the impression of floating in
the air.

It may be a combination of things like the palet used, the scene depicted,

In Lightsys, you can play with the luminosity by:
#declare SunLuminosity = 3;
used in the Light_Color(SunColor, SunLuminosity) macro you can use as light
source color.
I am not sure, but possibly you can also influence the luminosity by:
#declare Intensity_Mult = 0.80; // default [.75]
before including CIE_Skylight.

That shows it very well! The original photograph is nicely deformed this
way.

I know how I would do it, but it wouldn't be worth it. It would still
look fake. It takes a real-life artist to accomplish something this:
http://www.lilianbroca.com/index.php/mosaics-gallery.php
Your tables look like the Ikea version, which suits a modest Bistro like
this one. The whole scene reminds me of the kind of place I used to see
around Austin: a pizza kitchen with tables left over from when it was a
coffee house and a lucky cat on the counter left over from when it was a
pho shop. These places all seem to have been taken over by corporate
restaurants.
Houston family-owned restaurants are more resistant to corporate
take-over, but Houston doesn't have beautiful scenery or historic
architecture. There is something Romantic about eating a plate of
over-priced, under-portioned, glorified junk-food in a beautiful
setting, at least when you're immature and idealistic. The famous Oasis
(Garth Brooks slipped on down to it) in Austin was nothing more than a
burger joint with a view.

Your standards may be too high. I would be interested in your idea.

No, that level could not be programmed. But cruder result could hold
some charm.

Yes, it was really about the table-tops. They drove the scene.

There was a well-known student, cafe-type, hangout around the University
of Toronto called "Lickin' Chicken" Used to *be* a Lickin Chicken so
they just left the sign there.

Well, garden restaurants in the east village here have zero view.
They're built in the charmless backyard/airshafts of tenement buildings,
and shaded with weeds that grew into trees. But we love 'em and pay
$3000/mo for one bedroom closet apartments to be near 'em because this
is New York and gawd knows only New York has the right to call itself
New York.

Nothing revolutionary:
1. "Posterize" the image into an appropriate number of colors
2. Use marching squares to build borders between colored regions
3. Place tiles along the borders
4. Advance the borders and check for intersections
OR.... The slower, easier way
4. March the squares again, this time checking for tiles as well as
color differences.
