Another view. No fog this time, but with radiosity (using the defaults, with
brightness .6. I haven't yet worked out the best rad settings for this kind of
scene... OR for an animated moving-camera version, which is even more
demanding.)
No new changes yet, just more buildings (2500 for this render.) And I'm up to 19
different window/facade image_maps now (and their respective window-reflection
'hold-out' mattes.)
The random heights of the buildings-- the number of stories (storeys?)-- is
controlled with this...
ceil(2 + 40*pow(rand(PP),4))
.... so there are a minimum of 3 (because of the way rand works-- it never goes
to 0.0) and a max of 42, I think. I added the exponent to reduce the number of
really tall buildings... which actually wipes out many of the mid-size scales as
well. But it's fun to play around with.

Funny thing: I just now saw that belicose Trump statement on the BBC-- I was too
busy building my little city to take note of today's world events. ;-) N. Korea
has some nutty leadership... but so does the U.S!! Like two little bully-boys
daring each other to a fight in the schoolyard... with nuclear weapons. My
little city may go up in flames soon :-O
But I continue working... :-)

This is really good indeed. A building tycoon would lick his lips and
wring his hands seeing all that beautiful building space wasted on low
buildings ;-) But surely he is not aware of the hidden subterranean
problems impeding tall buildings in the first place. Interesting. I
would need to think about the local geology... ;-)

Ha! True enough. (I can think of one such real-estate tycoon here in the U.S.;
TRUMP TOWER would *never* have been built with only 3 storeys!)
I need a somewhat better 'algorithm' than a simple power-law, to restrict the
number of really tall buildings in my cityscape; I don't want to wipe out the
middle scales at the same time. I need to think on this awhile...

Of course, I could instead use a large image_map (or just a fancy bump pigment),
along with eval_pigment, to determine building heights (and placement)from the
pigment color at any particular pigment point. That has already been mentioned
re: grouping buildings into clusters, and I've used such an idea in the past.
It's probably a much better idea, with a more realistic city result too.

You could just define a simple bailout value, where after so many tall buildings
get defined, then it just skips any new ones....

Hi(gh)!

That's the basic problem with computer-based creativity - the current
human lifespan is just too short to do really great things! If we had
300 instead of 30 years left, what could we achieve in all those years,
especially when collaborating? Entire star systems with planets worked
out to a millimetre scale, simulations of complex civilizations
inhabiting these star systems, down to the very individual people... a
full-fledged Khyberspace in various historical and alternate-historical
modes, with the beards and turban ends of its Afghans blowing physically
correct in the desert wind, of course featuring all the immersion
technologies of 22nd/23rd century virtual reality... perhaps
Transhumanism will enable us to live theoretically forever (unless its
energy source run out) in those worlds... or even emulate pre-computer
age human life with death and afterlife according to the concepts of the
various religions... for the inhabitants of Khyberspace, there for
example might be an implementation of the gruesome Islamic hell, an
infinitely painful endless loop... which only the highest-ranking
programmers of Khyberspace may break, therefore they are worshipped by
ordinary Khyberspace Afghans as a collective Allah... while only a few
yottabytes away, there flourishes a hyper-scientific intergalactic
civilization of immortal near-omniscient superhumans!
Keep on coding!
See you in Khyberspace!
