I understand what you're saying--but after thinking about it, I don't think
it will have any different result.  The windows are already using ambient.
Now, if I make the windows transparent, but put a layer behind it that is
fully ambient, no one could tell that it was any different than the way it
is now.  Am I thinking about this correctly?

The difference, is that using patterns or iamge_map, two instances of the same 
windows layout will look different depending on that inner pattern. This can 
make things more interesting. 5 outer textures and 5 inner patterns randomly 
rotated/translated could generate 1000000's of combinations. Think of the cells 
pattern randomly translated and wraped around the axis.

I think that, when finished, this macro would be ideal for the POV-Ray 
object collection!!

Good work!!

Overall, it looks very sci-fi to me, and I specially like the glass domes,
but perhaps they are to whitish? I will do these more transparent but also
more reflective.

It's curious how I used a very very similar approach when I first tried this
some years ago... :) In fact, when I've seen your image, for a moment I had
a strange feeling of "deja vu".

Now, I'm not very imaginative for this kind of scenes, but I can pass to you
the advice given to me by a real architect: not even in the future the
cities will be that regular and homogeneous. That is, you need much more
variety in the building shapes and heights... and that's why I abandoned my
"sci-fi city" project: too much planning for a lazy like me. I'm attaching
the final render before giving up, as perhaps it can give you some ideas...

High!

Awesome... especially the lighting and colors, it gives the impression 
of a desert megalopolis, let's say Dubai City in 2030!

But I'm not sure whether I really would like to live there... just bare 
concrete, no parks at all and surely pretty dark in the lower floors!

And it must have taken ages to render this, as you used a good deal of 
radiosity...

Nice render!

You're certainly right that it is still far too homogeneous, and that is the
challenge, of course (although it seems my artistic theme lately has been
"monotony").  The next step would be to start writing macros that make
different kinds of buildings (like squarish ones) and incorporating them
(perhaps someone else would like to contribute some macros to the object
compilation??).  Also, all of these buildings are about the same average
diameter.  One would need some buildings that were considerably larger than
others. After that would be layout.  Perhaps future cities are not arranged
on a grid?  Perhaps they are arranged in series of tangent circles of
various sizes?

For Yadgar:

Actually, these images do not use radiosity.  I'm just using a dim,
purplish, shadowless light opposite my primary light source.

I have posted one version of the macro in s-f, but I am still working on it
so I will probably post newer versions later.

That's why we need to accumulate several macros. :-)

As the future city would have evolved from a contemporary one, throw in some 
"classic" buildings: square ones, relatively low compared to the tall circular ones.
Add some LARGE variation in hight: the newer ones are probably taller than the 
older ones. Higher buildings been shinier than lower ones.

It would help if not all the buildings were round.  Even where fashion 
or engineering forbids sharp corners, I'd expect most of the buildings 
in such a city to be rounded polygons, to use up more of the ground.

I've never used Povray macros, let alone written any, but I'd imagine 
that your macro can easily be extended to use prisms (sideways) for 
straight walls that match the lathe's profile.

No, you misunderstood me... I didn't relate my comment to your macro 
demo images, but to Jaime's rendering!
