There is a program out there called sine wave surfer that can make
seamless tiled images of all kinds of looks. From its web page comes to
mind one striking image of some kind of glowing green metallic ooze, all
seamless!
Rather than download this program, even if it were freeware, I was
trying to do the same thing with the isosurface PIGMENT feature in
Superpatch. I figured that the easiest way to make a seamless tile was
with a trig-function based pigment, viewed orthographically. I tried
around with several different functions, but everything essentially
looked like marching squares and circles.
Is there an algorithmic way to use POV to make a seamless tile,
especially with the superpatch?

Yes. Chris Colefax has an include file to do exactly this... I think you
may ask uncle Ken for the link, since I don't have _any_ of my
links/bookmarks left here *sobs*

If by that you mean the SuperPatch go to http://twysted.net and
you will locate it in the patch station section of Twyst's web site.
If you were thinking of something else I propbably have the link for
that too.
The Sinewave Surfer by the way is at:

No, I'm sorry, I was trying to avoid dling the official Sine Wave Surfer
and I already have the Superpatch. My question was a mathematical one.
I want, say, an irregular-looking pattern that is at the same time
tileable. Something fractal-looking, animal-scale-looking, or metal-bubble
looking. All of the functions I have plugged into the pigment function of
the superpatch look like boring arrays of circles & squares. Has anyone
gotten any formulas to yield interesting, REGULAR patterns in the pigment
function?
Here is some code I've used with previous options commented out.
pigment{
function {
//abs(cos(z))+abs(cos(y))+abs(cos(x))
// cos (x*2*rr)^2*cos(y*3*rr)+
abs(cos(x*rr)*sin(y*rr)/3+1/4*cos(x*rr/4)*sin(y*rr/4))^0.5
}
color_map{
[0.0 rgb<0 1 0>]
[0.6 rgb<1 1 0>]
[1.0 rgb<1 0 0 >]
}
}

I was simply replying to Mick''s post where he asked for an address.
I really don't have much to offer in regards to special patterns in the
superpatch. It really wouldn't hurt for you to take a look at what Chris
Colefax has done with an include file to make tilable patterns in the
official build of Pov. There might be some code in there that you can
learn from.
Sorry for the lack of help but it's the best I can offer at this time.

Hi
Habve a good browse in utilities someone came up with some textures for
superpatch which included some sine wave pigments.
I think it was called pigments.inc

You mean the one that can only be used in the Super Patch ? The one
that uses special macro functions and math routines available only in
the superpatch to achieve the pattern types in the include file ? Is
that that the one you are referring to ? I haven't seen it.

I've also tried to make that kind of tileable images,
but haven't achieved any satisfying results.
Chris Colefax's include-file have the disadvantage
that the textures used are averaged in the center of
the tileabled image, thus you can never make sharp,
bright textures.
I've also tried alternative camera-types, but if you
want the texture to tile both horizontally and vertically,
there will always be some parts of it that is enlarged
more than other parts.
So I'm afraid I can't help...
