only used it on Polydata, so it conforms to the outside of your actor. If you
want to measure internally, I’m not sure how you would go about that.<o:p></o:p></span></p>

<p class=MsoNormal>Hi all,<br>
<br>
I was wondering if anyone has used vtkDistanceWidget to measure the distance
between two points in 3D space? Ideally I want the widget to select
points from my actual data and not just any position on the screen. Has
this been done before?<br>
<br>
<br>
Thanks,<br>
<br>
John <o:p></o:p></p>
