to create ellipsoids, you can use instances of vtkSphereSource and pass
them to a vtkTransformPolyDataFilter. In that filter, you´ll have to
explicitly create a matrix trasformation, using the vtkTransform class.
You´ll have to invoke the Scale methods to properly specify the length
of the ellipsoid´s axes. Have a look at vtkTransformPolyDataFilter´s
documentation to see some examples.
