not sure if I got it; but I think you need to apply the transformations 
in your actors to their corresponding polydatas and then append the 
transformed polydatas

have a look to:

actor->GetUserTransform() // in 
vtkProp3D<http://www.vtk.org/doc/nightly/html/classvtkProp3D.html#a5cce6e4e754d06113adba06c184dc745>
vtkTransformPolyDataFilter 
<http://www.vtk.org/doc/nightly/html/classvtkTransformPolyDataFilter.html> 
// to apply that transform to the points in your polydata


good luck
sebastian
