Thanks for the info, but that definitely crashed the program :) It makes sense to update the modified time, but it didn't work in this case. I know by looking at the debug info that m_poly is updated. It contains new points each time I click. I'm not sure how to check if the polyMapper has been updated, but I don't know why it wouldn't be updated?<br>

Hi Greg,<br>
<br>
I think your m_vtkWindow does render the window again. But the input data is not updated, because it does not notice that its inputdata has changed. To solve this issue you should use the Modified() function. I m not sure about the preferred usage, but I think replacing m_poly->Update(); by m_poly->Modified(); will do it. If not try adding m_conn->Modified(); and m_points->Modified();<br>
