<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,<br>
<br>
I use vtkRenderWindows in which I'll use multiple actors ( for me : a surface and glyphs to visualize the vectors, stored in the point data of the surface)<br>
<br>
I need to access those actors from the renderwindow and by using GetRenderers()->GetFirstRenderer()->GetActors(), I am able to get a vtkActorCollection *.<br>
<br>
No problem to get the last one, using vtkActorCollection::GetLastActor(), but what about the first one? Or the intermediate ones if I had more than two actors?<br>
<br>
I tried to use GetNextActor() but it always gives me a NULL pointer.<br>
So basically I need something like GetFirstActor() or actorList[0].<br>
<br>
I found a LOT of people on Google looking for a solution to this problem, but no answers.<br>
<br>
Thank you for your help,<br>
<br>
Alexis<br>
