Hi,

I have 3 points (P1, P2 and A). They are lying in one plane, but not

along a world axis.

P2 should be rotated around A that vector P2-A ist pointing in the

same direction like vector P1-A. I have the rotation axis and can

calculate the angle. But I don´t know the direction of the rotation

(angle is always positive). Is there a formula to get this right?

Thanks.
