It seems that the VTK importers read a whole scene from file into a 
vtkRenderer. You can either supply your own renderer or get the default 
from the importer. The datasets, camera's, actors and mappers are 
accessible from the renderer object.

There is a VTK example for the 3DS-importer that shows you how to use an 
importer. You should be able to get your vtkDataSet object (superclass 
for vtkPolyData, vtkImageData, vtkPointSet, etc.) from the renderer 
through GetActors()->[... select an actor ... ]->GetMapper()->GetInput()
