Alex,

Please keep the conversation on the mailing list so everyone can
benefit and contribute :)

I don't think you'd be able to draw 2M spheres. If you just want to
see a set of points, you should use vtkVertexGlyphFilter on your
points, like this:
http://www.cmake.org/Wiki/VTK/Examples/Filters/vtkVertexGlyphFilter

and then put the output of the glyph filter into the mapper and have
only a single actor. I'll add this visualzation to the above example
tonight.

Good luck,

David
