<div>Hi everybody.</div> <div> </div> <div>I am rendering a volume and would like the user to be able to select a VOI. In that purpose, I used vtkBoxWidget, which is nice to select manually and view the VOI. But what I'm interested in is to get the data corresponding to the VOI selected for further processing. I was thinking of using vtkClipPolyData but I don't know how to use it in association with my BoxWidget.</div> <div> </div> <div>Maybe, there is another solution to get the data from that selected VOI or another way to select interactively the VOI.</div> <div> </div> <div>I would really appreciate any suggestion cause I am a bit stuck.</div> <div> </div> <div>Thanks</div> <div> </div> <div> </div><p>
