Hello everybody,<br><br>I am trying to retrieve the polydata linked to a particular actor. I have my actor saved in a list<br>I used the "GetMapper" function to get the pointer to a vtkMapper * and the I used<br>
the function "IsA" to test if it is a vtkPolyDataMapper.<br>The IsA function returns true and I used<br><br>vtkPolyData *pd = mapper->GetInput();<br><br>to retrieve the polydata, but somehow I don't get anything reasonable and the number of vertices is 0.<br>
<br>is that the right way to retrieve a polydata from the pipeline?<br><br>Many thanks.<br>Giancarlo<br> <br><hr>Un mondo di personalizzazioni per Messenger, PC e cellulare, <a href="http://www.pimpit.it/" target="_blank">scaricale gratis!</a></div>
