[vtkusers] Merge polydata surface with cube

I have a relatively flat polydata (like an undulating landscape).
I want to clip asquare section out of it and add a 'base to it so it becomes
a cube where the top side represents the clipped surface.
The new polydata should be watertight.

I have tried adding points for the cube underneath, clipping the surface and
running a Poisson resurface but the edges get rounded, and I would rather
not have to resurface the original data.

Any ideas how I can mount my surface patch in a cube?
