[vtkusers] implicit surface with polys qn..

[K.R.Subramanian]

I have 2D contours from a series of consecutive image slices. I need to
do the following:

1. Connect them up into a polyhedral mesh (actually linear
interpolation, which is polyhedral)
2. I want to treat this like an implicit function, in particular, be
able to do a membership test, inside
    should be positive, outside should be negative, on the surface
should be zero..

The surface is open at both ends (like a bent pipe)

As I am fighting a deadline,  if someone has done something similar, I
would like to know
the easiest way to do this using VTK.
