[vtkusers] vtkTransform::GetOrientation()

[George Kamucha]

Hi all,
I have just got a major shock after applying the
vtkTransform::GetOrientation(), due to the inaccuracy and the output
format, could I be doing something terribly wrong here? I tried
something very simple, below:

vtkTransform *trans = vtkTransform::New();
            trans->Identity();
            trans->PostMultiply();
            trans->RotateY(10);
            trans->RotateX(20);
            trans->RotateZ(30);
            trans->GetOrientation();

I was expecting the output to be just three elements (so I have read
from the Manpages!), but I instead got a matrix which after decomposing
( a lot of work!), gave seemingly the following: Y=9.39, X=20.3 and
Z=33.4. So I am wondering, how come I am not getting the three angles as
opposed to a matrix, and is the error usually this big?  (I am using vtk
3.1, a nightly, August 2000). Please assist.

Regards

George
