<div dir="ltr"><br>Hello all, <br><br>I want to extract a sub-image from vtkImageData given a closed set of points forming any arbitrary shape (may be a vtkPolyData).<br><br>I have been looking at vtk classes like vtkClipVolume, vtkExtractVOI, vtkImageStencil. I am no able to understand which way should be preferred over which to do my task. Also, I am not able to figure out the exact pipeline structure for these clipping methods.<br>
<br>Could someone please throw some light on this?<br><br>Thanks, <br>Prathamesh<br></div>
