2d-interpolation on non-equidistant data grid ?

Hi,

does anyone know of a piece of code which allows for 2d-interpolation on
a non-equidistant data grid (or an arbitrary array of vectors) ?

(e.g.: numericalData = { {0, 0, 100}, {2, 0, 101}, {2.5, 0, 105}, 
                         {1, 1, 120}, {2, 2, 110}              }    )
                          |  |  |
                          x  y  f(x,y)

( Interpolation[] doesn't like this )

 
Thanks,

Ralph Kimmlingen
