It is possible!!! There is nothing magic about the SphereSources - they
just produce a vtkPolyData. You should have your meshes (the output of a
vtkXMLPolyDataReader most likely?) as vtkPolyData as well.

You can position/orient the actor that you produce from the vtkPolyData
using something like this:

I suggest you take a look at the "Transformations" slide set here:

Good luck!!!
