Applied transformation matrix of vtkProcrustesAlignmentFilter in similarity mode


Is there a way to retrieve the transformation matrix that is applied by the vtkProcrustesAlignmentFilter?
We want to apply this filter to align 2 shapes (meshes of 10.000 corresponding points) on each other in similarity mode.
However, when we do so, the result is scaled down by approximately factor 4000 and we have no idea where this comes from.
In affine transformation mode, it does behave well, however we don’t want anisotropic scaling or shear transformations to be applied.

Kind regards,
