Nice algorythm for a circle passing through 3 points.

   Now do you have an equation for a circle/arc passing through 3 points
   in 3D space?

   Answer must be in terms that will allow drawing the circle/arc 
   (in "n" small segments ) from point 1 through point 2 to point 3.

   I'm no math expert, but I've tried this problem several times
   and still have not come up with the kind of answer I'm looking for.
