[vtkusers] vtkContourWidget on 3D-images

[Lars Friedrich Lars]

hi,

I'm using KWWidgets (vtkKWRenderWidget) combined with vtkImageViewer2 so that I can 'scroll' through a 3D-volume slice by slice.
Additionally I connected a vtkContourWidget in order to be able to construct ROIs on the individual slices of the volume. The problem is that this only works for the first slice of the volume (even if the vtkImageViewer2 displays another slice, triggered by invoking its SetSlice()-method through a vtkSliderWidget). How can I tell the vtkContourWidget (or one of its sub-components) on which Z-position (slice) I would like it to draw on? How can I 'synchronize' the vtkImageViewer2 and the vtkContourWidget?
The contour-widget VTK-tests/examples work on single slices ...
