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.

Thank you for the idea Bill. I'm thinking
about how where I can get a human model from.

No. I'm sorry if the title of my prior
posts have confused you people.
This shape uses another PhiFn() than the one
I used for the shape in my "The remains of an
iso sphere: Take 2" image.
I think that I'll soon post some source code
for this image to p.t.s-f.

Wow!
Thank you very much.
Bye.
