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
