Hi,<br>
<br>
Having a vtkUnstructuredGrid, is there any way of passing it to an<br>
object in a way that this object produces the original input calling<br>
GetOutput() and GetOutputPort(). Specifically I want to get the<br>
initial unstructured grid data by calling GetOutputPort().<br><br></blockquote><div class="gmail_quote"><br></div>If I understand you correctly, all you'd have to do in the RequestData function in your filter is</div>
