I'm using POVRay normal spiral1 scallop_wave with scale, rotate etc. It 
very roughly simulate threads, but is completely useless for multythreads.

I would like to superimpose several different wavy patterns, and 
probably something else for fluff. Maybe add, of maybe multiply them to 
each other. But for doung so, I need writing my own functions for 
normals, and I have no idea whether it's possible or not.

I'm trying to limit scene to static primitives, preferrably small, to 
avoid slow rendering.
