Use a vtkImagePlaneWidget, set its PolyDataSource (which is a plane) to be
co-planar with your clipping plane and its input to your 3D volume.  You
could even organize it so that if you move the IPW that your clipping plane
also changes.

Have a look at ImagePlaneWidget and VolumeRenderWithBoxWidget examples to
give you ideas on interactor widgets, clipping planes and IPWs.

Good luck,
