Quote - So in fact you don't have to construct anything. You just use your three vectors p, q and r as the rows of your rotation matrix, and that's it. Just be careful that they all have length 1 and are at 90 degree angles with each other, so that you get a proper rotation and don't deform your chain links.

Ooh.  Simple and elegant!  :laugh:  I would have expected it to be far more complicated, or even impossible.  But then I'm superstitious about rotations.  :lol:

I'll see what I can do with this information.  Thanks, odf!  :thumbupboth:
