Is it possible to decompose the mesh1 function into a vertical and horizontal
part? I have studied the source of isofunc.c trying to convert mesh1
into a .pov function so that I'd have better control over it, but
it was more difficult than I first anticipated.

What i really need is to apply one texture for the vertical strands
and another for the horizontal. I'm trying to make a patterned tablecloth.
I've also tried modelling the whole thing with repeating patterns
of sphere-sweeps, but it took serveral hundred megabytes for even a 
small piece of cloth.

I'd like to find a solution that doesn't include adding a new function
and recompiling the source.

You could probably try to overlay two different textured meshes with
slightly different parameters, but that would not be very elegant :-)

IMO it's not very difficult to generate 'half a mesh' with an isosurface
function, just start with a repeating cylinder function and distort it
with some sinus function.

I think Tor Olav Kristensen did some similar things recently.
