Hi All,<br>I'm trying to catch events from a vtkActor that notify any modification that would cause the rendered image to appear differently. Usually I can use GetRedrawMTime to know this information, but instead of polling this information I need to listen for an event that notifies the modification of the timestamp related to the actor redrawing.<br>
<br>Unfortunately I don't receive any event and I'm wondering if such an event really exists on a vtkActor. <br>Resuming my code:<br><br>// create my vtkCommand callback<br>vtkCustomCallback* onModify = vtkCustomCallback::New();<br>
<br>// add the ModifiedEvent observer<br>actor->AddObserver(vtkCommand::ModifiedEvent, onModify);<br><br>When i modify my actor or any of its previous inputs (mappers, sources, etc), the vtkCustomCallback::Execute is never called.<br>
<br>Thanks in advance for your help.<br>Fausto<br>
