<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">I have written a filter that runs client/ multiple remote server. This filter works correctly, from what I can see. (It just replicates a dataset, in order to create a
larger dataset in memory for testing and benching.)<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">I am trying to convert this filter to a plugin. It works local server, but fails client/ remote server. I believe that my problem is that I am trying to calculate the geometric
bounds of the dataset, and each of the processors is returning a different bounding box – representing the bounding box of this server’s data. What I want is the bounding box of all server’s data. I am using a vtkDataSet function called GetBounds.<o:p></o:p></span></p>
