user 'ingo' did nice stuff on IK (FABRIK algo).

Hi Mike (and everyone),

Fabien Mosen created a mannequin image for the IRTC back in 1998:

Nice, thanks. I have to take a peek at his code. It looks very close to the same
wood mannequin I have beside me. Don't have the female version. I just added the
screws at the ball joints. My physical mannequin has brass screws.

I still have the files. The problem - as far as I can judge at this 
stage - is that the mannequin needs Moray for posing and moving the 
different parts, after which it is exported to a POV-Ray file to be 
included in a scene. That was how it worked at the time. Possibly I 
would need now to rework such a POV-Ray include into macros to make it 
work from there. Not sure, and unfortunately I have little time to 
plunge deeper in the matter at present. On hold for now, but who knows...?

That is very true.
I got however a warning by Malwarebyte about a trojan at the site Ingo 
mentioned in the threat (https://chiselapp.com/....) in 2018. Real or 
false positive? I did not dare to go further. (I have not yet checked if 
I have a copy on my other laptop though).

have not heard of, nor had, problems with chiselapp, so far (fingers crossed
:-)); fwiw, for a while until last month, the private SSH key for the github
site was available "in public", worth bearing in mind.

Don't know what happened to that site, at some point I stopped using it.

The IK I've never finished. There is something wrong I couldn't fix, don't even
remember what. If anyone is interested in it in its current state I can zip
something up and put it in binaries group.

Regarding mannequins, there is also an ancient Japanese one. I posted it once to
one of the binaries groups so it wouldn't get lost. It is lady.inc by Yasunari
Iwanaga. I could not find it with google.

Thanks Colin. I've pulled in the files. Cool that most the mannequin forms are
modeled with a sphere/cylinder blob pairing.
Mike.

 Nice!
My first thought was that it looked like it came out of my old Quantum Robots
code. After reading your text I knew it didn't. Then 'I could have done that if
I
wanted to.'
A long time ago I went robot crazy. So I made a robot factory, with a few window
programs to help set some(well a lot) reusable poses. I used those poses as
keyframes in my animations. The thing is I made a lot of walking/running
animations. I could give the keyframe poses to ya if it would help.
 I used the full 3 element rotate.
 So a lot of conversion would have to be done :(

Have Fun!

>> I could give the keyframe poses to ya if it would help.
That would be great - I would love to see how the poses are handled. A biped
format that could be applied to any rigged character could be fun to program. :)
Mike

just a thought...I have Max and tons of .bip files. I should be able to write
the rotation keys out as a frame sequence - one .inc file per frame? A 4 second
animation would be 120 include files. :(

>> I used the full 3 element rotate.
That seems to work best for linked forward rotations...unless there's
a way to handle quaternions in POV. I need to go back and add 3 independent
rotations per joint. I got lazy.

The scene starts to get really impressive.
A lot of work!
