Hello, At this link you can see what someone has done with ArcGIS.
http://xbbster.googlepages.com/isoliner It is not open source but the standard version is free. I think 3-D kriging only allows a spherical model. "Isoliner is the ArcGIS extension for make grids and points theme with interpolate by Kriging's and triangulation method. Last version of extension include Slide Analyst as free function. Isoliner include additional 3D functions, interpolation by features, generation of random points."
