<TITLE>RE: [Paraview] Dataset name in a MultiBlock dataset and display of unstructured grid</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/plain format -->
<P><FONT SIZE=2> Thanks, Paul...The name part has been done according to your suggestion... The other question still remains:<BR>
<BR>
<BR>
The scenario is that: I have a reader which reads a multiple block data. Each of the data block is a unstructured grid. After i load the data and press the Apply button. The meshes are displayed in the view window which is not what i want. I just want the reader to store the data and a subsequent filter will be used to retrieve the data block by block and display them. The grid needs to be constructed in the reader since all corresponding functions are in the reader. The filter knows nothing about these. Another option is "eyeball" icon in the pipeline browser, is it possible to "turn off" by default?<BR>
<BR>
What should I do? Setting the block name is for the filter to display the options that the user can choose. Is this the right way to do it?<BR>
<BR>
Thanks in advance.<BR>
<BR>
Regards,<BR>

Hi Zhigao,<BR>
<BR>
If you are writing a reader or filter that returns a multi-block data set<BR>
you can name a block with the following:<BR>
<BR>
<BR>
MULTI_BLOCK_DATA_SET->GetMetaData(BLOCK_NUMBER)->Set(vtkCompositeDataSet::NAME(),<BR>
"PUT_NAME_HERE");<BR>
<BR>
If you are just using ParaView you can use the "Extract Block" filter and<BR>
select the blocks you are interested in. In the pipeline browser you can<BR>
change the name from "ExtractBlock1" to something more meaningful.<BR>
<BR>
