[vtkusers] How to generate multiple hyper-streamlines simultaneously?

[Sohan R. Ranjan]

It is possible to generate multiple streamlines simultaneously. One way
is to use SetSource() method to specify an instance of vtkDataSet whose
points are used to seed streamlines.

e.g. vtkPointSource rake
            rake SetCenter -0.74  0  0.3
            rake SetNumberOfPoints 10

      vtkStreamLine streamers
            ....
            streamers SetSource [rake GetOutput]
            ....

However this method did not work for HyperStreamlines.
Can you suggest how to generate multiple HYPER-streamlines simultaneously,
not individually?

Thanks.
