I had posted a link to my bones.inc forward kinematics include file here about
ten years ago.  The link is of course old and broken though, so I just uploaded
it to GitHub:

https://github.com/edrobotguy/bones

bones.inc allows you to create complex skeletons and attach POVray objects to
them.  Included on the git are a huge readme file and two sample POVray files
that use bones.inc, one for animating a bipedal robot and another with a snake.
For the robot, the skeleton is defined right down to the finger bones.

Animation is accomplished by establishing a Pose for a skeleton, where each
joint angle is specified, and then interpolating between Poses according to the
clock value.  Chains of these interpolations can create some very complex
skeleton movements with very little code.

I was going through the old e-mails here and I found this.  I didn't know if I
had downloaded this bone thing or not. I did!, in 2012. I've been playing with
robots for that long?! I had decided to make androids only. I set it up a system
that'll let you adjust bone length. But soon just stuck with one set of bone
lengths. I'm really into animation so I created another system that will take
poses files and with a little effort make animated robots. I'm Now working on a
windows program that will take some of that effort out of making that animation.

Have Fun!!

Thanks for re-posting this, I didn't know about it. Looks like a really useful
tool! I've tried writing a few *basic* inverse-kinematics scenes, and even those
get complicated; this system looks like a real time-saver. I hope to play with
it soon.

in case you missed it, ingo published an inverse- kinematics "system" (FABRIK)
end of 2018.  did a quick search but all I found was this (somewhat) related
thread:
