Hi,<br><br>I've got a vtkPolyData of points.<br>Sometimes, the user can choose one or more id.<br>Then, arrows are displayed from the center of each point to another point which doesn't matter.<br><br>My first idea was to create a vtkPolyDataAlgorithm (the filter) which have in input the polydata of points and in output the same polydata but with only the selected points.<br>Unfortunately, this does'nt work because I can't set a vtkIdList of the selected points in the filter.<br><br><br>How can I do this ?<br><br>Thanks in advance,<br>Regards,<br>Ben.<br><br><br><br><br /><hr />Votre correspondant a choisi Hotmail et profite d'un stockage quasiment illimité. <a href='http://www.windowslive.fr/hotmail/default.asp' target='_new'> Créez un compte Hotmail gratuitement !</a></body>
