[vtkusers] how to concatenate transformations

[meMyselfAndI]

Hi,

As the topic says i'm stuggling with the concatenation of transformations
(-> vtkTransform).

I'm implementing an iterative algorithm, which produces an rotationmatrix
and an transformationvector each iteration. Now i want to concatenate these
transformations.

if i apply the transformations each iteration on my vtkPolyData it works
just fine. i tried some things like just making a global vtkTransform on
wich i concatenate the rotation vtkTransform and the translation
vtkTransform in each iteration and apply that global transform on the
vtkPolyData -> seems not to work properly

i hope you can help me.

thanks in advance,
Tom
