Are you looking at this page:
http://www.vtk.org/doc/nightly/html/classvtkHedgeHog.html
?
If you click "List of all members", it will bring you to this page:
http://www.vtk.org/doc/nightly/html/classvtkHedgeHog-members.html

which has the function you're looking for. (They are functions of a parent
class).

Please see this example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/HedgeHog

The VTK6 way to do it is SetInputData, and the VTK5 way to do it is just
SetInput. Both are demonstrated.

Also note the use of vtkSmartPointer - this will let you avoid the giant
list of Delete() calls at the end of the program.

Good luck,

David
