Hi VTK users<br>
<br>
I'm trying to visialize cells in a vtkRectilinearGrid that satisfy
certain requirements, e.g cell data value is > 0. Basically I'd
like to see the outer faces of those cells.<br>
<br>
I already succeeded in my task by <br>
<ol>
<li>using a vtkExtractRectilinearGrid filter</li>
<li>passing it to a vtkThreshold filter</li>
<li>using a vtkDataSetMapper. <br>
</li>
</ol>
However, the visualization is quite slow and unresponsive, for large
grids memory consumption is too high. I assume this has to do with
the unstructured grid that is created by the threshold filter.<br>
Does anybody see a more effective approach to visualize a subset of
cells in a rectilinear grid?<br>
<br>
Any help is appreciated.<br>
<br>
Cheers,<br>
Mike<br>
