[vtkusers] HDF5 with VTK

[Mike Jackson]

So basically, you need to read the data from the HDF5 file and render  
that using VTK. This can be done for your dataset but you will need  
to write the conversion code. The basic outline would be something like.

Read a timestep of HDF5 data into memory (assuming it will fit)
Instantiate the appropriate vtk object (would vtkImage be appropriate  
or vtkStructuredGrid?)
copy all the data to the vtk object creating scalar and vector  
attributes as needed.
save the resulting file to a vtk file (vtkXML....Writer)

View data in ParaView  (or vtk for that matter).

Does this help?
