I rewrote the hair generating algorithm... the previous version was simply a
flat mesh of triangles, and I wasn't happy with it.  This one generates a
more cylindrical shape, and is constructed of a mesh of smooth triangles
instead (including surface normals).  Only a few parameters are programmed
in so far: base diameter, tip diameter, length, number of segments, base
curl, base texture, tip texture.  It assigns individual textures to each
segment that are interpolated from base to tip.  The next two additions are
tip curl and scraggle.  Ultimately, it will duplicate the way hair and fur
are generated by Maya (so I hope).

What's wrong with bezier patches?

Hmm, I don't know... haven't looked into the possibility actually.  I chose
to use a triangle mesh since I wanted to use triangle texture interpolation.
I've never messed around with bezier patches, but i will take a look and see
if it's possible and if it has any benefits.

Got the tip curl implemented now too.  Incidentally, the amount of curl on
the base and tip is unlimited.  I rendered this one with the tip curl set to
360 degrees to demonstrate.

Damn that's cool.  Please make a Moray plugin for it, too? :)

Holy cow!!!!! This is really impressive stuff man!

I'm definitely going to use this in the near future, believe me. (for
animations also)

Well thanks :)
Hadn't thought about animations yet... actually I've never messed around
with animation at all.

Did some work today on scraggle, which is close to finished.  Scraggle is
basically Maya's term for turbulence it seems.  Anyhow, will post a sample
when its done.

Hey Doug!

Your work is really fascinating!

As for the animations - a little one with curling changing from 0 to 360
degrees would look damn good already.

Keep up the good work,
Florian
