Bill,<div><br></div><div>Thanks. The example is helpful, but doesn't show how to extract individual actors. The vtkActor I display (after discretemarchingcubes) is a single actor that covers all the labeled volumes. Each component is colored separately because I use a color table.</div><div><br></div><div>I would now like the user to click on a single component volume and return an actor corresponding to that label. Is there a way to do that? I have already tried creating multiple actors with separate call to discretemarchingcubes for each individual label. However, that is much slower than just passing a range of labels with one single instance of DMC.</div><div><br></div><div>Thanks,</div><div>Thommen<br><br><hr id="stopSpelling">Date: Mon, 16 May 2011 23:31:53 -0400<br>Subject: Re: [vtkusers] Multiple actors using discretemarchingcubes<br>From: bill.lorensen@gmail.com<br>To: thkorah@hotmail.com<br>CC: vtkusers@vtk.org<br><br>Look at this example.

I am able to use vtkDiscreteMarchingCubes to generate differently colored and labeled volumes. At the end of the visualization pipeline, I get a single vtkActor representing each labeled volume. How can I get separate vtkActors for each component.<div>
<br></div><div>I understand that I can call discrete marching cubes on each label separately and store the resulting actor. I was wondering if there was a more correct way to extract the actors separately.</div><div><br></div>
