Because the previous thread has become so large, it is hard to keep an
overview. Thus I am starting now this thread as part 2 of that
remarkable thread.
THE PROJECT
To develop a scene where tall futuristic skyscrapers rise above cloud
level, not necessarily on Earth.
PUBLIC DOMAIN
Such scenes can be very beautiful. My original intention was to make
this scene public domain, allowing everyone to use it. But the scene
received so much valuable input of so many members of our great
community that I feel I need to ask everyone who helped for their
permission - a lot of source code was submitted by so many members.
I can even imagine, each POV-Ray community member with interest in this
project can design the interior of his/her own flying home (a flattened
bubble with a diameter of 20 meters) and submit it to this thread as
self-sustaining INCLUDE file. Those home bubbles hover above or below
the clouds or can land or even swim on the water, or they are anchored
in large swarms along the futuristic skyscrapers). The bubble design
will at one point be submitted by me into this thread or an own thread
for you to use. Basically, it has one round floor and a transparent
wall/roof. Only the bottom is non-transparent, it hosts the antigrav
modules in a ring along the lower bubble inside. The center of the
bubble has one lowered floor and one raised floor. On three sides, the
bubble will have docking mechanisms for towers or other bubbles.
WHERE WE ARE NOW
The basic scene layout is there: a layer of clouds, two suns, even a gas
planet.
1
At the moment, there is a big problem to set the colors correctly for
this scene, as each color change causes many other colors to change
unpredictably, too. This need to be fixed, then everyone using this
scene can easily use the own colors of desire.
2
The two suns don't look like suns but just like luminescent discs. No
glow, and their colors are not correct, too: the large sun should be dim
red, and the small sun should be white-glowing blue, each having a glow
around them.
3
The illumination doesn't come from these two suns, but from a
traditional light_source. making it come from these two suns, and using
their own light color, would be more authentic.
4
The large gas planet needs some overhaul, but that is a fairly easy task
I can do on my own. Priority for that, however, is low at this moment
(as I can solve that at any given time by myself).

I think anyone offering help considers their SDL freely given, only nice to
mention if you feel the need. If I'm wrong maybe we will hear differently.
Ambitious goal, not sure I could do more but it has potential.
There could be inherent problems with the realism aspect of the suns and
atmosphere. I know some people have attempted it in the past with some good
results, but I don't remember how simple time of day or motion changes affected
them. A scene can become unexpectedly different due to even slight changes of
camera/light/objects.
I think of POV-Ray as not being a reality simulator, more of a simulation of
reality. If that makes sense.
I suppose a good enough facsimile should be possible anyhow, sun orb auras and
all. Once the formulation is found anyway. If the idea is to forego any tricks,
such as halo disc objects, in lieu of pure 'media' it might prove difficult as
you've no doubt seen already.

This is really impressive. The choice of using lighting at dusk (or dawn?)
instead of 'mid-day' makes the entire scene look magical. The same goes for the
very nice hazy cloud effect.
Thanks for posting your code. I've been playing around with it, and made an
area_light to replace your point light... which makes the scene even SLOWER to
render, of course, but I noticed that your test-building on the left was casting
too 'sharp' of a shadow through the foggy atmosphere, compared to the size of
the large Sun. (I only noticed the sharpness re: that one building, so *maybe*
the area light could be assigned to *just* that building, in a light_group, to
save rendering time. I haven't tried that yet, though.) Anyway, here's the
light...
light_source
{
-z*9999.0//< 50, 100, -250 >*10e4
color 1.3//< 1.0, 0.62353, 0.46667 >*2
area_light
<450, 0, 0> <0, 0, 450>
6, 6 // total number of lights in grid (4x*4z = 16 lights)
adaptive 1 // 0,1,2,3...
// area_illumination on
jitter // adds random softening of light
circular // make the shape of the light circular
orient // orient light
rotate < 20.0, 240.0, 0.0 > // altitude, azimuth, tilt
}

Surrounding the Sun(s) with a sphere of emission media (not too dense, and with
a 'spherical'-pattern color-map bleeding off to transparency) might work for the
glow(s).
Over the years, I've discovered that media colors do indeed change the
appearance of background object colors; it's a typical (and expected)
side-effect of media's color filtering. My own workaround for that has been to
radically change the colors of the background objects (your Suns, for example)
to try and 'compensate' for the color change. I usually have to do it 'by eye'
with test renders and experimentation. BTW, you can even use *negative* color
values for those objects-- like rgb <-.5,.3,-.7> for example -- to 'subtract'
unwanted media colors there, if you need to.

I tried rendering cloud these days.
Using media is easy to get not bad result.
This picture is subsurface material version. When translucency rise. It is not
like cloud enough. I'm not very knowing why. Cause when cloud is not dense it
should like be.

My best guess is that it doesn't look anything like clouds because in
clouds you have a somewhat gradual change in the density of water
droplets, whereas the subsurface light transport model is designed for
cases where the density of the scattering agent changes abruptly at a
well-defined surface.
Directionality of scattering may also play a role (POV-Ray's current
implementation only supports isotropic scattering), but I don't think it
matters much in this case.

Media is easy to get not bad result, but still have some limit.
This time I used the correct scattering color of cloud, and added some emission
to simulate multiple scattering effect(emission strength should proportion to
the sun power) , emission color I just guess.
For this cloud size this simulation is not bad.

This looks much better as clouds :)
I like all of your previous attempts - they are useful for other types of
materials being modeled. You should save / post the parameters for those
results for future reference.

It looks more like the foam you get from detergent. Maybe when there has
been a discharge into a river, to me.
And, keep hold of the code.

I suggest to consider, to add this code to the INSERT options of
POV-Ray. Or, to the code collections on the POV-Ray objects page.
Or both.
And the clouds you all helped to develop in my own scene, should be
added to the POV-Ray objects page, too, ans complete environment
including the haze layers as well.

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.

Olala! Thanks for telling me. Will try it out. :-) :-D
But we need to find a way, to get a glow around the two suns, too.

Is there any location, where "this" and "dens_cloud" are defined? I
feel, I am missing some previous code here. :-)

On your last (high-attitude) cloud image, i would apply a tiny scale
attribute to your clouds. make them just a little bit flatter, maybe 10
to 20% only.
Your low-attitude cloudy-mountains image shows clouds that are not dense
enough in their center, not hiding the mountains well enough yet. I
believe, if you increase the density inside the centers, you should be
finished with the cloud coding. :-)

My approach will not allow me to rise the density much more, or it shows more
artifact. That's one of what I said the limit of the media previous. It can
simulate not so dense cloud, but more density it can't.
The two pictures that I last post is in the same cloud setting. Just change the
camera position. I want to express that my approach can simulate cloud nearing
the physical reality, not just an inconstant result.

"dens_cloud" is mine. It outputs the shape of the cloud from a function, I
usually use function to control the pattern. You can use your own density
pattern instead.
#include "functions.inc"
#declare f_test =
function(x,y,z) {
0.32*sum(i, 0, 4, pow(abs(f_noise3d(x*pow(2, i)/0.4, y*pow(2, i)/0.4, z*pow(2,
i)/0.4)), 2.5)/pow(2.0, i) )
}
#declare f_cloud_base =
function(x,y,z) {
0.5 - f_test(x,y,z)*3*3*z*exp(-3*z) - 0.32*3*3*z*exp(-3*z)
}
#declare dens_cloud =
density{
function{0.5 - 0.2*f_cloud_base(x,y,z)}
color_map{
[0 rgb 0]
[0.5 rgb 0]
[0.56 rgb 1]
[1 rgb 1]
}
}

Sunset:
this image I just assigned scattering media for the cloud. You can see the cloud
is too dark.
Even I set the extinction smaller than 1.0(this is equal emission some lights)

Too dark is caused by lacking of multiple scattering, so I fill-in some light
with emission for it.

for the sunset I use rgb<1.00,0.161,0.01>*strength for my parallel light as sun
light. It is from a sunset photo, I measured the color.

The images still look nice. Sad only, that I self have no understanding
of media, I wished I could help here. Sounds like you should propose a
new feature inside the BETA section of this newsgroup, or expanding
existing features to make it possible to increase the density further.

The issue isn't so much whether it is /possible/ to increase the
density, but rather whether doing so gives /realistic results/.
The problem is that the scattering media model is designed for cases
where the media's density is non-uniform, but low enough that the single
scattering contribution is dominant (i.e. a typical light ray will be
deflected from its initial direction at most once), and the multiple
scattering contribution (i.e. light that is deflected from its initial
direction more than once) is negligible.
Compare this to the subsurface light transport model, which is
specifically designed for cases where the density is pretty much
uniform, but high enough that the multiple scattering contribution is
dominant.
To extend the scattering media model in such a manner that it gives
reasonably realistic results for high-density media, a monte-carlo-ish
rendering approach would have to be used, where secondary rays would be
shot here and there along the light's path (even recursively). Expect
noisy results and/or high rendering times.
This is in fact on my wishlist, but other stuff takes priority.

Thank you for this insight.
I think, looking to the list of persons actively involved in the
developing, POV-Ray needs again some more promotion. It is such a
unique, great, possibilities-loaded render engine, it deserves to be
connected to all school and university students. I think, we really need
many more developers who are into POV-Ray rendering. But that is just my
personal opinion.

For some strange reason, it seems I am unable to change the location of
the two colors inside my pigment_maps ("MyHull" texture and "MyInterior"
texture, both at the top of the code), even when changing the numeric

Can anyone of you test and find out, if you encounter the same problem?

See the image. I tried successlessly to raise the upper edge of the
sand-brown area in my pigment_map...

Then redefine your texture maps using A and B

Thanks. I actually found some errors already, but they are not with the
pigment_map.
But what I recognize, if I apply RBGT colors with transparency 0.75 to a
shape, and use a difference to take of another shape from it and that
shape has also transparency 0.75, the result is a pigment with no
transparency. Strange.

Emissive media with a sprerical pattern and some turbulance.
One sphere for the sun itself, and a larget, concentrical one, for the glow.
The media for the glow should have a lower emissivity that the main one.
The media for the sun should probably be OK using an uniform density.

Not enough samples. Try using at least 3 times as many, maybe even as
much as 50+ times more.
