<p class="MsoNormal"><span style="color:#1f497d">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.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="color:#1f497d">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).

<p class="MsoNormal" style="margin-left:.5in"><u></u> <u></u></p>
<p class="MsoNormal" style="margin-left:.5in">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.<u></u><u></u></p>
<p class="MsoNormal" style="margin-left:.5in"><u></u> <u></u></p>
<p class="MsoNormal" style="margin-left:.5in">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. <u></u><u></u></p>
<p class="MsoNormal" style="margin-left:.5in"><u></u> <u></u></p>
<p class="MsoNormal" style="margin-left:.5in">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?<u></u><u></u></p>
<p class="MsoNormal" style="margin-left:.5in"><u></u> <u></u></p>
<p class="MsoNormal" style="margin-left:.5in">Thanks very much for any insight you can give.<u></u><u></u></p>
