[Opengeoscience-developers] vtkNetCDFReader

[David E DeMarle]

I don't see an API for that on the reader, so I suppose the only way to
request a subset is via the pipeline mechanics. Ie, set UpdateExtent before
you call Update.

To go from cdms variable to vtk object, we might adapt the code that
Aashish and I wrote in UVCDAT for the ParaView displays. That was written
partially at the paraview python level but it won't be hard to adapt it
since we more or less ignored the proxy layer and assumed we had direct
access to the data.

Note: we should use vtkNetCDFCFReader for the most part as that subclass
adds understanding of the CF conventions that the climate data will most
likely have and will give us better results.
