[MOAB-dev] VTK structured mesh outpu

[Paul Wilson]

Hi Iulian,

We are much more interested in the writer, but might be convinced to 
support a reader as well :)

We would want to explore the SCD interface to see how it could best 
support this.

Our use case begins with MCNP mesh tally output files that are always 
structured mesh.  There is a native reader in MOAB for these files, but 
not as rich/robust as we'd like, and it does NOT use the scd interface, 
instead making an unstructured representation.  There is also a reader 
in the PyNE toolkit that does ultimately use the scd interface, but then 
also relies on MOAB's vtk writer which stores an unstructured 
representation.

The key to a structured (Cartesian) mesh VTK writer is having access to 
the x,y,z bounds without having to infer them from the set of vertices.

The rest is probably straightforward.

Paul
