Any thoughts on how to do decent human hair, and not stick-on-your-head
type haircuts - Long hair and stuff too.

	You could start with bumps scaled very small in one or two directions,
then add turbulence. To get a smooth, wavy turbulence, scale small, use the
warp version, and scale back up again. Use phong or specular, and
"metallic".

	bumps scale <0.0001,1,1>   {a scraped-back straight-hair look) 
		scale 0.1
		warp{turbulence 1}
		scale 10

	(play with the numbers, this is untested)

	You might also try a radial normal with very high frequency to get the
"whorl" effect; or use several normal_maps, each including the previous
one,
to give the effect of layers.

	You could do bangs, loose ends, etc. with a surface (bezier patch?) whose
pigment varied from clear to hair_color abruptly with high frequency and
some large-scale turbulence. Careful anisotropic pre- and post-scaling
could create density changes without upsetting the parallellism.

Actually, you want to AVOID strict parallellism, since this will cause 
moire patterns due to aliasing.  Better to have slightly sub-parallel.

Perhaps a custom version of povray with sphere sweeps can be used.
The web page is: http://www.informatik.uni-bremen.de/~vader/pss/pss.html
But you will probably need an external program to model the hairs.

You might try a height fiels, done in black and white, with the pixels
beings set sexactly as you like.  dont know how youd get it to curve and
stuff, but it might work.

If you're willing to wait for the internet release of the POV 3.1 beta
youe can do it with a new macro I've written for my current IRTC entry.
I'll be posting the macro with the entry source code. The current round
ends this month.

Any scuttlebutt or rumor about when any such release might occur? I've
suspended work on an include file utility since learning about the
macros
in 3.1. They'd be perfect for what I've done with some extremely ugly
but
functional workarounds in 3.0. If it's a long way off, I'd just as soon
finish the thing in 3.0 and recode for 3.1 later, but if it's anywhere
close, I'd rather not waste the time....

In any case, props to the POV-team for the awesome upgrades coming in
3.1! 
The new directives, macros and file capabilities will leverage the
talents
of all POV-ray artists immensely.

This is not really a serious suggestion, but I've just made a simple
animation with POV with growing hair. If anyone's interested let me know
and I'll put it on the web (for a while).

Fabulous news. Thanks for all the hard work, on POV 3.1, the new
servers, etc. Three cheers for the POV-Team!
