You'll have to use a vtkSimplePointsReader
http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/SimplePointsReader to get the
data that is already in the file, then combine it with your data with a
vtkAppendFilter :
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Filters/AppendFilter , then you
can write the result with your vtkSimplePointsWriter.

Also, I suggest you take a look at these suggestions for asking questions:
