[osg-users] different result rotating Vec3d for Quat or Matrixd

Hi, may be this is a newbie question but I would like to understand the reason of this behaviour. I have to calculate the coordinate of a 3D point wrt a different coordinate reference. The new coordinate reference is simply rotated wrt the first one. I tried two different implementations with
