CLOUD CITY: "HABITAT" sub thread
Please see below the scene code. I started to work on the habitat module
which hovers in swarms around the intended futuristic skyscrapers and
above and below the clouds.
I have a problem:
I make the hull hollow with a "difference" of the same shape but
slightly smaller side. However, I get strange results when watching the
habitat from below: the surface should be smooth because only from the
inside shape (difference) I take again some items off with another
difference. This should not impact the outside shape. And still, it
does. Help is welcome.

I just noticed something in your scene code that is probably unnecessary, in
your 'BigSun' and 'SmallSun' objects: the use of CSG union there...
Original code:
// Small Sun
#declare SunSmall = union
{
sphere
{
< 0.0, 0.0, 0.0 > 1.0
pigment { color rgb < 0.23529, 0.11373, 0.46275 >*1.0 }
finish { emission 0.0 }
}
scale 66.0
translate < 160.0, 25.0, 112.0 >*33.0
}
The scale and translate at the end only apply to that one object, so a union
isn't required; you could more easily write it as...
#declare SunSmall =
sphere
{
< 0.0, 0.0, 0.0 > 1.0
pigment { color rgb < 0.23529, 0.11373, 0.46275 >*1.0 }
finish { emission 0.0 }
scale 66.0
translate < 160.0, 25.0, 112.0 >*33.0
}

Yes, you are right. The UNIOn comes from a time when I tried to add
another hollow media sphere to each sun, to simulate (successlessly) a glow.
I eventually want to give another glow try, somewhen.

scattering with type3 (mie murky) or type5 + eccentricity 0.9 is the most

Hi, big thanks.
As I understand it, I need to add this media into the declaration of
each sun, is that correct? And if so, would the sun sphere need to be
hollow?

No, don't waste your time with that single building/light_group idea, sorry. I
tried it and the results are not what I had imagined. I don't know how to
describe the resulting effect, but it definitely looks 'wrong' with the clouds
and atmospheric medias.
