Have a look at the functions in the DiscreteMath`ComputationalGeometry`
package which is included with version 3.0.
Also, the book "Mathematica Graphics" by Tom Wickham-Jones includes code
for triangular interpolation which generates a function for
approximating irregular data. The packages are available from
