<div dir="ltr">Hi <br>I have been trying to get "simple filters" to work with composite data inputs.<br>What I do is this :<br>1. create the simple filter ( say a vtkContourFilter )<br>2. Set its executive to a vtkCompositeDataPipeline<br>
3. Set its inputConnection to the output port of a XMLMultiBlockDataReader( the source of my <br>composite data ).<br>4. Now when i do an Update() on the contour filter and try to Get its Output using <br>a GetOutput() i always get a NULL value. <br>
<br>The executive that i attached to the filter above however returns the proper output dataset<br>when i call its GetCompositeOutputData() function.<br><br>Is this expected behaviour ?<br>Am I missing something ?<br><br>
In general is the method mentioned above proper to get normal filters to work <br>with composite data ?<br><br>--<br> regards<br>shekhar<br>
