Does anyone know of resources for interpolating on a mesh that is not Cartesian, i.e., has tablulated function values at "random" points in n-dimensional space rather than at vertices of a rectangular array?

Thanks

There is something called "Shepard interpolation" which is commonly used to interpolate over randomly spaced points. I have only used it/seen it for data that is a function of 2 variables.

Just search for it on Google, there are plenty of links.

Thank you, Mark. Let me check it out.
