I'm not sure if this image is finished
or not now.
What do you think ?
Should I change something ?
I should probably mention that I had
to "hand correct" the finished image
somewhat at the sphere's "south pole".
(Because there seems to be some
calculations that are not calculated
correctly by POV-Ray. Increasing
max_gradient or accuracy did not help
at all.)
I have also used Micrografx Picture
Publisher to increase the contrast a
little.

All it needs is a guy looking up at it. Make him so small that he can be
mistaken for a spot, then you notice the shadow and the scale suddenly
shifts...

Fantastic, I like the image just as it is.
Congratulations,
Fernando.

If you defined the spiral correctly, that's because the spiral never ends,
the detail increases towards the poles infinitely. That is, if I understood
the description of the shape that I read a while ago correctly.

In an equiangular spiral (reverse Mercator projection of oblique
parallels), that would happen at both poles; TOK said only one.
What's the formula?
(Love the textures.)

If that surface structure is a normal you could make it part of the
isosurface geometry. Apart from that, do you have 'normal on' in
radiosity?

I think it's quite obvious that spiral structures lead to infinite
gradients which can't be rendered correctly under all circumstances.

Looks nice.
Will it form a whole sphere when combined
with the y-rotated other textured one?

I tried to render your scene file posted in p.t.s-f
last month. But I could not find any problem
on the image. Did you use the same function?

Sorry, this has nothing to do with the question, but I wanted to ask you
something:
Today I have had a problem with a file you sent to p.t.s.f. (Iso quilt and
Carpet: 3 torii) in november 2001.
If I render it, I only obtain 2 torii and a black background.
I wanted the iso carpet for an imagen I'm working on, but it seems like it
has dissapear.
Maybe it's caused by the beta versions.
(AMD Athlon 600 Mhz, Win 98SE, Povray for Windows 3.5 beta 10).
Any help?
Thanks in advance.

Yes, it is caused by the syntax change. I posted the revised one
in p.t.s-f as a reply of that message. (I've added checker and hexagon
pattern in that scene) I hope it is helpful for your project.
