[vtkusers] "best" way to represent an ellipsoid

[Day, Robert]

A question, good people...

I am fitting spheroids and ellipsoid to point data, and I want to show the
fitted geometry along with the point data.  What would be the "best" (or
perhaps most correct or most vtk-ish) way to do this with vtk?

I have been using a vtkSphereSource and passing that through a transform
filter.  I have also considered using a vtkTensor3DGlyph or an implicit
function.

The last (implicit function) obviously has the most generality; but I have
to run it through a contour filter to get a surface.  Is the tensor glyph
the way to go?  What do other people do?

Thank you for your advice.

Rob.
