[vtkusers] How do I save all slices of a volume from vtkCutter to another canvas?

[Sankhesh Jhaveri]

Hi Magnus,

First of all, if the goal is to just slice the volume consider using
vtkImageReslice (
http://www.vtk.org/Wiki/VTK/Examples/Cxx/ImageData/ImageReslice) instead of
vtkCutter.

You can simply set the output image data of the vtkImageReslice to a
vtkImageActor and add it to a vtkRenderer as in
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/InteractWithImage

Hope that helps.
