vtkSpyPlotReadert Reader does not "correctly" build dataset
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
MultiBlock data should have AMR box filled with global extents of its associated image data, but spyplot reader instead fills this with an indicator of weather or not ghost cells have been stripped from this block.
Given the CTH format, much information needed for post-processing filters is available in the reader but not provided, for example:
Level 0 dx Data set Origin Standard block size Index space bounding box(like chombo problem domain)
In addition all processes need to know the global structure of the data set, (ie have access to AMR Boxes which contain the global extents of each block.) This type of information is needed for neighbor finding etc...
Currently as the items are not provided each instance of the post processing filter then must attempt to deduce and communicate this information amongst its process,leading to complicated code, extra communication and processing overhead.
