you are looking for an interpolation over an irregular grid

you may try DiscreteMath`ComputationalGeometry`TriangularSurfacePlot
or the ExtendGraphics packages from Tom Wickham-Jones on MathSource.

A spline over an irregular triangle mesh is a current research topic
and I don't expect that you will find a solution in Mathematica.
