newbee question

[Casteel, Don]

Thank you for taking the time to help me out.

My first problem is figuring out how to put the coordinates and attribute
values into a DataSet or PolyData.

PointSource outputs PolyData, I just can't figure out how to get there with
my own data.

x-y-z >> vtkPoints >> ????
attribute-per-point >> ???? 
???? + ???? >> DataSet or PolyData >> StructuredDataSet or ImplicitModeller

Here's what I've done with PointSource:

PointSource >> ImplicitModeller >> ContourFilter >> SmoothPolyDataFilter >>
PolyDataNormals >> PolyDataMapper >> Actor

You can't go from raw to Volume without a structure.  In other words, you
must 
have a structured dataset to use most of the volume routines.  To get a 
structured dataset from raw, you must use Delaunay3D, ShepardMethod, or one
of 
the other ones which is a subset of vtkDatasetToStructuredPoints method.

You might take the PolyData which you have and do a ContourFilter over it
and 
see if the resulting iso-surfaces are all you really need.
