[vtkusers] vtkClipClosedSurface using a finite plane

[sebastian ordas]

Dear all,

I'm successfully using vtkClipClosedSurface in an application for 
slicing a set of perfectly closed meshes.

Now I would like to cut through my scene with a finite plane or somehow 
restrict the slicing extension to a given extent

My target  application is an ultrasound simulator. I would like to avoid 
slicing through the complete scene (i.e all organs in my scene) but 
within the US image plane only

I´m trying to combine several planes in vtkClipClosedSurface, but I´m 
not getting the pretended results

Any hint will help

many thanks
sebastian
