Hello guys how is it going?
I have here for you two tutorials about some advanced rigging feautures for a stretchy IK by using chopnet!
you can find it here on the sidefx website itself :
http://www.sidefx.com/index.php?option=com_content&task=blogcategory&id=191&Itemid=345 [sidefx.com]

in the first part we build the regular stretchy Ik
in the second part we are gonna add some more advanced feature like the knee/elbow lock and knee/elbow slide!

comment and critiques are more then welcome guys!
If you want to be update for the next coming tutorial just subscribe to the newsletter :

C&C appreciated

As a side note, this is similar to what the InverseKin CHOP uses for Solver Type=Follow Curve, Curve Normals = Best Guess on an object-level path. Takes the normal from the first path cv and propagates that through so that you can do full revolution twists.

BTW, I like the suggestions on the cross posted thread on odforce.

thank you sir , yes that s exactly my final goal I am trying to replicate my quaternion spine (which means i need to twist along the curve) in houdini and then give it to the community as I did with a lot of custom maya nodes.

I was also thinking then to try to write a python sop that should be fairly easy 8) 8)
