If I understand you correctly what you want is for a Vector3d to be
facing the same direction. Do you want the vector in local or world
coordinates?
Assuming local coordinates then you could build a Transform3D using
your axis angle and then use it to transform a vector pointing along
the -Z axis.
If you want world coordinates then you need to apply your axis angle
to the TransformGroup, get its local-to-vworld transform, and then use
this transform to transform the -Z vector.
good luck
