Capping

Hi everybody!
I am trying to reconstruct a surface from noisy 3D data. I already know
that the surface must be within 2 voxels of filtered data. Using this, I can
construct a worst case limit. This results in an unstructured grid. Based on
scalar data for every point in the unstructured grid, I would like to contour
a better approximation of the surface. Due to the noise, the contour
surface is not always within the 2 voxel limit. Can I have a general and
oddly shaped capping surface for the contour? In the end I want the
contour within the unstructured grid or the surface of the grid to fill out
those regions where the contour and the grid surface intersect.
It is not a simple case of capping the top and bottom. Maybe someone
can help me?
Cheers
Uwe
