Description:
In the case of w3 is already located in the plane of v1 v2 v3 prior to the computation of the last transformation but needs a rotation of PI around the axis v1-v2, the dot product of the vectors axis_w and axis_v equals -1. This leads to a nan in the subsequent computation of the rotation angle by the acos function!
Solution:
This special case must be treated seperatly.
