[Paraview] Input text

  OK, I confess I'm still stuck. All I'm wanting to do is read an ascii file
in the form x(n), y(n), z(n), a1(n), a2(n), . . .  Where xyz are spatial and
an are other attributes for colorizing or other viz tricks.
  I really don't know where to go with the c++ VTK code you sent me (being
new to this, and not even having the VTK documentation).
  I looked at the particle viewer web page you sent me to, which also left
me ice cold -- not knowing what to do. Namely, how do I get the vtk particle
reader to work from ParaView?
  I've been roughly through the ParaView book and see where you bring in a
package, so, how do I get this simple package? I also see the ParaView XML
for reading in files, but, then don't I need a reader for those files? Back
to the beginning!
  It seems I must be missing something. There's gotta be something dumb for
simply structured ASCII, namely, something to use with import package. My
files are not that huge (yet) and I was hoping to go up the learning curve a
bit later.
  Or am I just nuts and have to plow through VTK first.
Thanks
