Just some more experiments with using isosurface functions as patterns.
Again, these use Isofunctions.inc. I am thinking of adding all of the
patterns I come up with to Isofunctions.inc if there is any interest.

Well they are certainly interesting, but I don't think I see the point.
What is the difference between this and a regular pattern?

You can create totaly new patterns that POV-Ray itself does not have
built into it.

I like. Do they have to be grayscale or can they use a 'color_map' in the usual
way?

Hi Chris. Good work. How did you manage to get the patterns to go down to a
point?? Is it the spherical warp (that I haven't tried)? I can see a use
for such a pattern for making the iris in the human eye.

Function patterns can use any color map. The only reason I used a
black-white color map and an ambient of 1 was to show the shape of the
pattern itself without confusion from bands of colors and shadows.

You can define a custom pattern without having to patch the source code.
You also have more control over waveforms and can more easily mix
patterns to get the desired result.

No, the actual patterns work that way. I used the sin() function to
avoid having a discontinuous line where it is mapped back to itself and
get the repetition, and Phi(), R(), and Theta() from the include file to
imitate the mapping.
