Anyhoo, I have been messing around with IK for robotics, and I decided to
implement it in POV. After about a month of hacking, something is really
beginning to take shape. I googled POV-related IK, and really found very
little. (I think Rune has something squirreled away somewhere that is more
significant that the neck include file, but he doesn't appear to be letting
go of it...)

I'd just like to find out if anybody knows whether or not I'm duplicating
work. I am planning an all-out walking system, but right now I have an IK
system with arbitrary numbers of joints, lengths of segments, starting
position, axes, and goal. It fits neatly in under 200 lines (though it will
get bigger again when/if I really get going ;)), and reaches an random
goal in just more than a second.

Is this a 'hello world' project everyone does? Or should I finish the sucker
and throw it online for people to use?

Thanks for your feedback.

There is my "How to make an IK leg" on http://runevision.com/3d/povgoodies/
but it can only be used for 2-bone structures. My unreleased bone system for
AL the Alien basically just combine a few of these and the rest is forward
kinematics. I have never succeeded in creating "real" inverse kinematics.

I'm very interested!

Gotcha.

Good! I'll keep at it then. I just noticed a problem this morning, but over
the course of my classes I think I've got a couple solutions. No, I just
have to decide whether or not to use the harder, more elegant one...

Anyway, I'll keep at it, if I'm not just repeating someone else's work. As
far as I can tell, the closest thing to what I'm doing is a separate
program that can give a POV file for a given frame of an animation.

Anyway, thanks for the feedback.
