Hi,
Thank you for your reply.
I am not interested in a simple rotation matrix around an axis, but in
finding the angles corresponding to a 3D rotation matrix.
I compute VectN which is the vector normal to my surface, and I am
interested in getting the rotation parameters that bring VectY to VectN.

Mathieu
