Does setting the image update extent on the output of MC help. Something like ?<div><br></div><div> marchingCubes->GetOutput()->SetUpdateExtent( 10, 50, 10, 50, 10, 50 )<br><br><div class="gmail_quote">On Fri, Feb 24, 2012 at 10:05 PM, Cory Quammen <span dir="ltr"><<a href="mailto:cquammen@cs.unc.edu">cquammen@cs.unc.edu</a>></span> wrote:<br>

<br>
I've looked at the VTK documentation and wiki examples, but couldn't<br>
find an example of what I want to do.<br>
<br>
I'd like to generate an isocontour from a subregion of an image. I<br>
could use a vtkExtractVOI to extract the subregion of interest, but<br>
I'd like to avoid copying the image data. Is there a way to specify<br>
the extent on which the vtkImageMarchingCubes filter operates on its<br>
input?<br>
<br>
If there is an alternative that saves memory, I'd be happy to hear that as well.<br>
<br>
Thanks in advance,<br>
Cory<br>
