[vtkusers] Visualizing Points in space

[Mike Jackson]

I have a vtkUnstructuredGrid object with about a 100,000 thousand points. I
would like to put a "sphere" on each one.. Or even just a Tetrahedron to
keep memory down. What is the most efficient way to do this?
   Do I need an actor for each point? And a Mapper for each?

Thanks
