This is an illustration from the 56th IPCC Summary Report, published in 
2268. After climate change drove humanity to an artificial structure 
around the Earth, the Panel continued to monitor the planet and to 
report on its changes.

The President of the United States In Exile (POTUSIE) has been reported 
to comment that "again, a useless piece of paper had been produced by a 
group which, unrelentingly, pursued its own agenda."

A few comments about the image:
- Bald Eagle is thanked for little code that renders "an alternative 
spiral". It is the basis for the rocky outcrop height_field.

- One million trees (2 types) were planted to fight rising CO2 levels.

- Fifty thousand boulders (also 2 types) were thrown to earth. Nice to 
mention that their sizes gradually decrease with distance from the camera.

- The space structure was built in Silo2.

this is exquisite.

critiques first.  there is a boulder below and left of center perched on its
end.  it looks peculiar.  there is another, closer, below and right of center.
the boulder at the base of the near tree lower right has a bright band at the
bottom that looks like sunlight coming thru the rock; surely an honest depiction
of the geometry but if it were me i would cheat and get rid of it somehow.
  i do not see a million trees possible in this scene.  perhaps they are
de-scaled to be the moss on the ground?  or is the one-million purely part of
the scifi dialog?
  the boulder at the lower left has a shadow at the top that i mistake for the
silhouette of a bird.  which reminds me there is no animal life in the picture.
how would it affect the purpose of the picture if there were?  what if there
were a mad-max figure in the scene?  a bit much?

the craggy outcrop in the distant center is something i drool for.  wonderful.

the thing that rivets is the space structure.  mesmerizing.  i can not make it
out however, very mysterious.  it seems to be three structures helixed around
themselves; but their cross-sections are very unclear.

somewhat off-topic, but how do the people in the space structure live as far as
gravity/acceleration?

thank you for this image, a living presence burned in my brain.

I agree with green's critique plus a floating rock in front of the tree 
in the foreground.
Niggles aside it is impressive. The space structure brings to mind, the 
Mobius offspring of a twist drill, writ large.
The composition is good.

Very nice.
My nit picks :
To the right, just in front of the tree, there is a boulder that float 
slightly over the ground.
Next, there are two boulders standing up in an impossible position : 
Centre of gravity is not over the area of contact with the ground.

LOL!

The image is beautiful-- lots of nice detail and realism. Kudos!

For the rocks, I would suggest burying them into the ground a little bit.
Assuming they have been there for ages(?), the natural wind erosion of the
ground around them would have filled in some dirt and sand. Or maybe they are
'fresh', from some kind of recent Earth-shattering explosion?

Nice textures for the rocks, btw.

Thanks - glad to have provided something useful.
I would never have recognized it  :D

What does the heightfield image look like?  Did you make "an alternative
spiral" and then blur it to get the tapering into the plain?

<Dr. Evil> "One MILLION trees...." </Dr. Evil>

I think that phytoplankton, prairie grasses, and cannabis sativa (that other
grass), would make a far bigger dent, much faster.

....Why?   From where?
Aside from that, and others comments, I'll join in with agreeing that your rock
texture is indeed very nice.

> - The space structure was built in Silo2.

Nice.
Though very different - it kinda reminds me of the "Kluchikov" isosurface.
I think I'd like to see some additional renders of that.

Nice, sombre, atmosphere, Thomas.
When I saw the picture my first thought was, what a funny clouds.
Then I realized they must be the "artificial structure around the Earth".

I was almost going to say: I did that on purpose ;-)

Especially the boulder hovering over the ground is a glitch in the code. 
It has been hammered down into the ground already. The others will be 
treated likewise as soon as I have tracked down their location.

A bit of overkill I am afraid, but there are - literally - one million 
trees in the visible part of this scene. Most are invisible because the 
horizon is far away ;-)

You may have worries about the render time but no. It is true that most 
time goes into the plotting of the locations, but those are written away 
into a separate file, and used afterwards for the planting proper. 
Reading those locations is fast.

In the upcoming version, there will be some animal life (how much is 
still a matter of debate with myself) but there is no place for a Mad Max.

Correct. Three - structures with an irregular, asymmetric, section - are 
helixed.

Thank you indeed Stephen. The rocks need a bit of additional attention 
but nothing to worry about. I was going to write that lighter-than-air 
boulders were the consequence of climate change, but I am afraid nobody 
would swallow that. ;-)

Yes, I was also thinking into that line. The idea is whether the ground 
is mostly soft or mostly hard. It probably is in-between as the slope 
represents some ancient scree surface. So, more burial of the rocks is 
indicated indeed. I have already been working into that direction.

Honour where honours are due: this particular texture (as well as the 
vegetation) came from a scene by Cedeaq:
http://news.povray.org/povray.general/thread/%3C4ca93948%40news.povray.org%3E/?ttop=371487&toff=200&mtop=351355

His post is the last one in this thread.

I had "rediscovered" his code and used it in:

I took the image rendered by your code as basis for further work in the 
GeoControl program, which transformed it into a /real/ height_field. As 
a next step in POV-Ray, I added a second height_field for the near 
plain, and a simple disk{} to join to the sphere representing the sky 
(distance is 10e4 pov units).

Yes... One has to produce impressive figures to the international press

Of course! However, trees are so much more sexy!

Oh, you know, sloppy programming, too much coffee, too little dried frog

Thanks indeed. Yes, the structures is intended to be tantalisingly vague.

Btw, the technique used to achieve this "out of the atmosphere" kind of 
look was initially developed by Bill Pragnell in some distant POV-Ray 
past. It is very simple to achieve with the following code:

//start code
background {rgb <0.01, 0.01, 0.01>}

// a sky sphere
sphere { <0, 0, 0>, 1
   texture {
     pigment {rgb 0 transmit 1}
     finish {diffuse 0}
   }
   interior_texture {
     pigment {
       gradient y
       color_map {
         [0.0 srgbt <0.6, 0.7, 1.0, 0.5>]
         [0.7 srgbt <0.0, 0.1, 0.8, 0.5>]
       }
     }
     finish {emission 2 diffuse 0}
   }
   scale 10e4
   hollow
   no_shadow
   no_reflection
}
//end code

The magic tricks are the transmit values of the interior_texture, and 
the strength of its emission in the finish block. Every object, being it 
a moon, a spaceship, or whatever you want, placed /outside/ of the sky 
sphere, will show up as if it was truly in space. You can add any kind 
of media to the sphere in order to simulate the atmosphere of course. I 
advice against the use of fog{} in this context.

Yes indeed, it does. It is a beautiful object.

It was one of those things I had to be reminded about. 2003 was a kind 
of transitional year for me and I did not access and/or download all the 
code that interested me. So, I missed that one somehow but your hint was 
enough. :-)

I shall make a version with this ring.

This is what the Kluchikov Ring looks like, without modifications to 
number of 'turns' or 'blobs'. Intriguing structure to say the least. I 
am going to play with the two mentioned parameters to see what fits best 
as a space station.

No trees here, but note that the boulder 'problem' has been resolved.

With 10 turns and 10 blobs, the sky looks like this.

Nice but I believe that, if I use the Kluchikov Ring, I shall position 
it differently: more as a 'classic' space station above the Earth surface.

:)   That's an interesting experiment - I must say that I liked your original
shape better, and the rough/matte texture with greebles gave it a bit more
"solidity"/visibility as well.

If there's a way to increase the radius of the horns/cables in the Kluckikov
isosurface that might work a little better.


My original thought was to get a better look at the space station on its own, or
from an off-world perspective, or even an on-ship perspective  :)

I'd try by adjusting the threshold a bit.

The threshold is certainly something to play with indeed in this 
context, but like Bald Eagle says, and I agree with him, I probably 
shall keep the Kluchikov Ring for a different scene after all.

Ah well... Real World news is an excellent Muse I am afraid. I have 
worked for about ten to fifteen years in the Climate Change science 
world so, when some scientific nitwit who happens to be the leader of an 
important nation tells us, with much aplomb and not hindered by any 
inherent lack of knowledge, how we should see the world, my primary 
reaction is similar to the bull in an arena. The result is this image... 
and its text. :-]

If you worked in that field, would you allow me to mention the
environmental project of a Facebook friend of mine? His name is Enrique
Lescure, and he founded the Earth Organization for Sustainability. If
you want and have the time, check out the EOS, they are on FB but also
have their own website. Tell me what you think about them.

Very nice!
After all these changes on the Earth, I'm expecting to see some insects.

This is the final version. Assuming that all mega-fauna, i.e. larger 
than a dog, has gone extinct.

Indeed. Scenes often have a background (other than /background/) ;-)

They certainly are there. A bit too tiny to be seen though, except if 
you think of huge buzzing swarms of them of course.

an evocative image.  I like the added details on the structure.  which leads me
to ask: just how big would such details need to be to be visible from Earth?
also, can you provide the approximate dimensions please (a la Niven :-))

those birds look like fairly large (circling) vultures.  ;-)

For the sake of the image, the details are huge, but so is the structure 
itself of course. As far as dimensions are concerned,I let you make the 
calculations:

The structure's basic size (in POV units) dx,dy,dz = <22.237729, 
2.253802, 22.237729> is scaled 10e4 in this scene.

Eagles, sir, eagles! But yes, they are large indeed. I was mainly 
referring to the earth-bound species...

Have you ever seen Future Boy Conan (The incredible tide)? Little bugs, 
suddenly and in a huge quantity...

This truly is the final version of the scene. Only subtle changes to the 
aspect of the Ring Structure.

Basing on your writings, the book might like you. I know that reprints 
have been made, but there are still some old versions on the web (e.g. 
http://www.highharbor.net/doc/tide.pdf).
I personally loved the anime version of Miyazaki, but it depends on 
personal tastes.
