I wanted to use vtkCookieCutter for a project to cut a hole in a surface but for now, it’s only meant to return the mesh lying inside the given contour loop, while I wanted to opposite. I tried other filters like vtkClipPolyData but none of them give a result as clean as vtkCookieCutter does.
So I only want to know, from VTK devs point of view, if it’s possible to update the filter to use some kind of InsideOut flag like with vtkClipPolyData. If so, I would try to do it and make a MR.
