[Paraview] New data object types

[SamuelKey]

Paul,

I am not sure how familiar you are with PV, so your issues may be way 
beyond the suggestions I am offering --

PV will read and display multiple source files. (I have been able to 
read in simultaneously an Exodus-II formatted file and an EnSight Gold 
binary formatted file.) Each displayable object can have its own filter 
pipe-line; each displayable object can have its visibility independently 
turned on/off; animation will use whatever is on the screen. I routinely 
generate a data-set for proofing the mesh, BC's and IC's followed by a 
separate file set for computed results. You can actually read the same 
data set twice and filter them differently for displaying two different 
results. You can translate and rotate one data set with respect to the 
other to watch two different views in an animation. The list goes on.

Using these features maybe a lot easy than getting entangled in writing 
your own reader.

Firstly, my reader is taking an input file, running it through our meshing software and loading the structured mesh that is created into paraview.  The program also creates other files, e.g. one that gives the boundaries for that structured mesh.  I was hoping to store that addition information (like where the file is stored) for some of my other filters to use.  Instead, would it be possible for me to pass this string in another output from the reader so that I could still use the other filters associated with vtkMultiBlockDataSet as well?

>> Sorry to keep asking questions but I need to know how to add an extra DataObjectType in a plugin.  The new DataObjectType is derived from vtkMultiBlockDataSet (with some additional information stored) but I don't know to register it in order to use as the output to my reader and input to my filter.  Is this even possible with a plugin?
