I have a humans finger (DCS DOF node which has local coords) and I want
to point at an object in the scene (DCS node which could have local or
world coords). I can get the world coord of the finger and draw a
vector from finger to object using pfMakePtsSeg which gives me a
direction but in a world unit vector. Graphics 101 Question: How can I
get the appropriate matrix to rotate my finger to point at the
object.(Assume the hand is always pointing in the general direction of
the object)?
