Try http://news.povray.org/povray.binaries.scene-files/20553/ for a string
simulation. I am working on some string macros myself that will do what you want,
but the code is far from release. I'll get an anim together and post it later in
the week if you like.

This looks realy good, sove quite detailed modelling.

That would be great, thanks. I think that is probably beyond my current
POV/maths skills - I'm having to re-learn stuff I forgot years ago...
I'm working on an IK method of positioning the fingers at the moment, so I
haven't really got time to do string stuff as well!
thanks,
Mark Hanford

I can't see how the hand would close. Am I missing something? I really like
the "clips" at the joints.

I'm thinking that a few chips in current packaging (SMT, PGA or similar),
rather than the 14 pin DIPs in your scene, might fit a bit better with
style of the robot hand. DIPs are more than a little long in the tooth,
you know. :-)

Sorry, it's all I had to hand (hahahaha)
Actually, the components came from a totally different project, and were
modelled from real bits I had lying around here from some old school
projects (more than a few years old...)

See my post in p.b.a on this.

The Hanford hand is coming about nicely i hope in no suffering of the home
life... =] I like the fingertips... ??? Looks rubbery and useful for leafing
through papers ect... =]

Thanks very much. I do most of the work on this on the train going
to/coming from work. The wife might disagree, although I'd sware that I
spend no more than half an hour (or is it 3) on this in the evenings :)
Time goes astray sometimes...
Oddly enough, I like the finger tips, even though they are pretty much
unchaged since the original (box+sphere)-box-box. I might try to find a
way of putting some fingerprint-type roughness onto the tips...
see ya
