[vtkusers] Extrapolation

[Jose Luis Pina]

Hello:

I have a cubic grid (nxnxn) with scalar values associated and I want 
calculate the scalars in new points around the cube (n+2)x(n+2)x(n+2),
I know that some filters interpolates but I wander if there is any one 
witch extrapolates,
,interpolation with the intermediate points outside the grid.
Anyone know if this filter exists?

Thanks in Advance.
