Indeed ;-)
Nice work. It must be dark down in the streets. I suppose you can widen 
them but with current land surface prices... :-)

It is curious to see how some themes like landscapes or cities are 
regularly visited again and again. Each time a little different.

Yes... no streets yet, just the ground plane. As you say, infinite planes are
expensive :)

Yes, this is something I've been intending to have a bash at for a while now. I
was surprised how quickly I was able to get convincing results. :)

Here's another iteration.

This one looks absolutely superb, very convincing.

This one feels like real.

It's a very nice cityscape.

Much improved over the first, now some suggestions:

* The fire marshal will get into a snit if you don't put some fire 
escapes on the residential buildings.

* In a lot of major cities you will see a section where there are a 
small number (from three to six) buildings that are identical.  These 
are usually residential.

* I observe that all of the buildings have an overall rectangular shape. 
  While most buildings of this nature are that shape, every major city 
has a few that are based on cylinders or pyramids, or even something 
irregular; Detroit's Renaissance Center is a good example (in a town 
that's otherwise turning into a dump).  Toss a few of these into the mix.

* In major cities, especially along thoroughfares with lots of 
pedestrian traffic, the ground floor of a building will have storefronts 
and lobbies, making for an exterior arrangement that is different from 
the floors above.  Whether by accident or design, the ground floor is 
obscured in what you've shown us so far.

* Real cities also have a few roads that do not run either parallel or 
perpendicular to the rest, and perhaps even curve a bit as well.  These 
roads are generally major thoroughfares, that will be wider than all but 
the very largest buildings.  Even the newer American cities, which for 
the most part look like graph paper from above, have a few roads like this.

* Toss in a river, either with or without a major fork in it.

The last two will of course make for major challenges in your macro 
coding.  It might be better to code one macro to make the basic layout 
(rivers, hills, major highways), then have another fill in the minor 
streets, and then have another simulate the zoning board, and then 
finally place the buildings.

Regards,
john

awesome!  Much better than the classic povray ones.

then again, we now have much better hardware.

we need a night shot. :)

Hi!
Another round of hyper-realistic or useful suggestions:
-Birds, clouds, aircraft contrails,
-The environment, would a mountainous horizon perhaps? Or the sea coast? In
Spain it is very typical that the horizon line in the big cities the pollution
is
observed in the environment (though our politicians are bent on denying it)
-Satellite dishes, you will not see unless you look at them.
- Advertising?
- The reflection in the windows. The point is that in reality, crystals are not
perfectly aligned. Add a little bump distortion to make us believe we are seeing
a
photograph.

btw, excelent job and nice renders

Thanks. That hazy layer of atmosphere is a very important cue :)

Good idea, especially for that north american look.

I already thought of this - one of my next jobs will be to adapt a greebling
macro to produce discrete city blocks. An obvious option will be to produce
residential-type 'estates' with identical (or similar) towers.

Yes, this too is on my list, but needs some thought to avoid needless work. I'll
try to knock up a generic round shape not limited to cylinders.

Very deliberate, due to the absence of roads as much as anything! It will be
relatively straightforward to produce a separate ground floor I think.

Yes, I'm painfully aware of this... :) I think I'll stick to regular roads in
the short term, but it would be nice.

This means I will also need a bridge macro ;)

As you suggest, this will undoubtedly end up being a small library of layered
macros (assuming I stick with it!) I'd also like to expand on the roofing
options - there are only 2 types of roof in the latter image, so some more roof
furniture would be good, maybe a spire or pyramid. For low, long buildings, I
could try gabled roofing. I was also thinking of trying polygonal blocks with
buildings around the edges, for a more european feel. Parks would be useful to
open up some space. And let's not forget the suburbs...

I shall post progress as it occurs :)
