I would expect the following to give you the number of objects (i.e.
actors) only:

  vtkVRMLImporter *importer = vtkVRMLImporter::New();
  // or vtk3DSImporter *importer = vtk3DSImporter::New();
  importer->SetRenderWindow(your_render_window);
  importer->SetFileName(filename);
  importer->Read();

  int nactors = importer->GetRenderer()->GetActors()->GetNumberOfItems();

(this is from memory; so there might be a typo in there)
Did you try that?

Of course, this all relies on the fact that the different objects
were in fact saved as different objects by the application that
generated the VRML/3DS file in the first place.
