// .NAME vtkEllipsoidTensorProbeRepresentation - A concrete implementation of vtkTensorProbeRepresentation that renders tensors as ellipoids.
// .SECTION Description
// vtkEllipsoidTensorProbeRepresentation is a concrete implementation of
// vtkTensorProbeRepresentation. It renders tensors as ellipsoids. Locations
// between two points when probed have the tensors linearly interpolated
// from the neighboring locations on the polyline.
//
