[Paraview] [EXTERNAL] Idiot's Guide to Programmable Filter

[Scott, W Alan]

Dennis,
The Python/ Programmable filter is a black box to me (i.e., I won't be much additional help).  However, the place i would start would be the new, super-duper ParaView Guide.  Kitware - and especially Utkarsh - have done a great job on it.

Rather than giving the link, here is how to find it.  It is sold in paper form on Amazon, and also is available as a .pdf for free (lacking 3 chapters, not related to the python filter).

paraview.org/ Resources/ ParaView Guide.  This includes the link to the .pdf.  You are interested in (at least) chapter 13.  It is listed under master section II, Reference Manual.

All,

I'm a little confused by what objects are inside a programmable filter.    I have a multi-block EXODUS dataset.    When I read this in it is a Exodus2Reader object (sp?) and I can access the blocks, pointdata, celldata, etc in a python script.

Once I get inside the Programmable filter, the  blocks of the input[] seem to have different member functions than they did in a Python script.   So I can't figure out  how to get connectivity,   number of cells in a block, generate new cell variables, etc.

So, if I'm in a Programmable Filter, what object do I look at in either the Paraview or VTK class libraries to understand what the properties of the block are?

Thanks very much for any insight you can give.

Dennis
