What is Dual Quaternion rigging anyway...?
And what, if any, is the advantage over traditional Poser rigging? Mind you now, I am NOT asking Poser to adopt that rigging. I am ONLY asking people who know, to explain it to me.
There was a tutorial over on Rendo Free Stuff that answers this question in great detail. You might wanna go see if it's still there. I believe it was another AllStereo tut.
This paper should explain it all
