[vtkusers] Rotating a Polydata around an arbitrary axis not centered on the origin

[Gideon Valch]

Hello,

I need to rotate a polydata around an arbitrary axis (not X, Y or Z) not
centered on the origin.  Is there a preferred way of doing this in VTK? I
believe the URL below describes the transformations. But I suspect there is
an easier way of doing this in VTK.  Any help would be appreciated.
