(warning - crosspost. This was on the devel list a week ago with no resolution).<br><br>I am trying to make a filter that takes a vtkPolyData as input and produces a vtkGraph as output:<br>
<a href="http://rpi.edu/%7Edoriad/VTK_List/vtkNearestNeighborGraph/" target="_blank">http://rpi.edu/~doriad/VTK_List/vtkNearestNeighborGraph/</a><br>
<br>
I get a bunch of these errors that make it look like I have not set an input:<br>
vtkStreamingDemandDrivenPipeline (0x89d60a0): Input port 0 of<br><div id=":yz" class="ii gt">
algorithm vtkGraphToPolyData(0x89d5ac8) has 0 connections but is not optional.<br>
<br>but as far as I can tell I have set all the connections properly. Can anyone see something I have done wrong?<br>
<br>
Thanks,<font color="#888888"><br><br>David<br></font></div>
