You can get the ID of a particular point using some of this:

http://www.vtk.org/Wiki/VTK/Examples/HighlightSelectedPoints

You can then create a new point/vertex/mapper/actor to "move" the point, but
you will have to figure out a good way to update the old set of points so
that the point in the old position is deleted.

Thanks,

David
