So you have written a vtk filter, then I am assuming you have some main() in which you are creating a VTK-pipeline to use this filter? Are you setting up the inputs correctly? Try calling Update() directly on the filter, does that result in calling of your RequestData() method? <div>

you trying to use your filter? Are you trying to define it in a ParaView
plugin? If so, you should be able to leave out any of the _EXPORT
declarations and it should work OK.<br><br>-Ken<br><br><br>On 9/21/09 9:02 AM,

__declspec( dllimport ) on my computer,but if I used that macro to define my
own filter class it would met some link errors .If I use the macro VTK_EXPORT
or did not use macro to define my filter class ,it can complie well,but
it did not work.I tried the debug.I found it would not invoke my RequestData
function at all,and the it would not invoke
vtkUnstructuredGridAlgorithm'RequestData methord either.The program invoked
the method RequestData form vtkAlgorithm class directly.I don't know why? what
should I do if want to define my own filter? Thanks a
