If I want to show a cube, I don't turn the camera by 180 degrees from it.
I badly read in English, but I well see the picture. I study changes in source
code looking at the picture. But, in your case I have nothing to begin.
:))))
If you wants to show the sky, turn the camera towards the sky.

...., I must say, if you want to use it for the environment(lighting), it is not
very well yet. First of all, what's the real extinction coefficient of our
atmosphere. I don't know that very well. The current value is just my guess.
Secondly, the sampling method of the secondary scatter which I implement is not
very good. But you can turn off the ground reflection by setting 'ground_albedo'
zero. It will eliminate the most obvious artifact. Finally, I should calculate
the output color of the sun again(in the output text file).
This image is the comparison of the ground_albedo 0.2 and 0.0. You can see the
artifact disappear.

Can you download it again? Because I just downloaded and tested it
immediately(unzipped it, then open the file click the 'render'), it is nothing
wrong.

When the render finishes, this is what my folder appearance.

And that is correct for me too. Maybe you should emphasize that
half_render should be put standard to /false/ so that the whole sky is
rendered, which is more comprehensive. It may take a bit more render
time but that is no problem.
I still have a lot to test but I like it.

projection (2) gives an error message. In fact, #case(2) is empty.

just noting things while paying.
- you should replace /ambient/ by /emission/ per POV-Ray version 3.7.

Thank you.
That's right. I will put it on the 'false' next time.
