I also am interpolating all active data into a vtkMultiBlockDataSetAlgorithm so the end product will behave similarly as a vtkExodusIIReader object.<br>
<br>
Anyway, I can't get the cell data to interpolate. The point data is working fine (change the variable to 'point') to show this result.<br>
<br>
I was hoping you could take a look and see what I am missing, I images it is something to do with the vtkPointInterpolator, but I can't seem to find the solution.<br>

Thanks,<br>

Feel free to add this an example with the data, when I get the python version fixed up I will add it to the examples wiki as well.<br>
<br>
Thank you for your help.<br>

I found the problems with your script.<br>
<br>
vtkPointInterpolator: The point arrays will not be interpolated unless<br>
PassPointArrays is off. And the source and input data must add the<br>
field data as the active scalar.<br>
vtkInterpolateDataSetAttibutes does not interpolate field data. To<br>
interpolate field data each input must add the field data as the<br>
active scalar.<br>
<br>
Neither of these are obvious. I have attached a c++ example that is<br>
based on your script. I changed a lot of the names to help me debug<br>
the problems.<br>
<br>
I would like to ass this c++ code as an example, once I make a few<br>
more changes. Is that OK with you? I would also need to add your<br>
datasets.<br>
