Hi Bjorn,<div>As I recall, vtkImagePlaneWidget already has a polydata describing the boundary of the plane. You could get that and manipulate it instead of mucking about with a cutter / tube filter...</div><div><br></div><div>
You can either directly manipulate the plane property (<a href="http://www.vtk.org/doc/nightly/html/classvtkImagePlaneWidget.html#aa967a678dc64d006ef7d9c9bce703e77">http://www.vtk.org/doc/nightly/html/classvtkImagePlaneWidget.html#aa967a678dc64d006ef7d9c9bce703e77</a>) or get the polydata (<a href="http://www.vtk.org/doc/nightly/html/classvtkImagePlaneWidget.html#a118b91779af7e29ab0162b6109531b95">http://www.vtk.org/doc/nightly/html/classvtkImagePlaneWidget.html#a118b91779af7e29ab0162b6109531b95</a>) and send it to the tube filter if you really can't do without the tubes.</div>

The vtkCutter is then used to create tube outlines where the cut plane intersects some 3d mesh structures. However, when I render the resulting outline, the outline tubes are slightly offset from the vtkImagePlaneWidget in the direction of the normal. I was expecting the outlines to be positioned exactly on the vtkImagePlaneWidget plane, since I used GetOrigin() and GetNormal() from the plane widget to define the cutting plane.</div>
