[Paraview] netCDF grids and Paraview 3.3.0

[David E DeMarle]

Hello,

We do not have a netcdf reader because that format is generic. You can
store anything you want in a netcdf file. Therefore if ParaView were
to open up a netcdf file it would have no idea what to do with it.

However, the netcdf library is already included in VTK and thus
ParaView. What is missing is a layer which understands the layout of
the specific content you have placed in netcdf files, and then makes
calls into the netcdf library to read the data and map it into
ParaView's internal data structures (vtk data objects). If you wish to
go about doing this, I would recommend taking a look at the
vtkMINCImageReader. Also, the converters that you mention could
probably be adapted into readers.

The same situation is true for the HDF5 library. For that the good
folks at ARL have contributed XDMF to ParaView, which does the mapping
for the data that they store in HDF5 files, based on the data
organization that they use (an XML meta file which describes the
content of the HDF5 file) for their data.

cheers,
Dave DeMarle
