Yes, I mentioned the Delaunay triangulation in my original post, which
gives a linearly good approximation to the actual integral. I was
wondering if a quadratic approximation was feasible with current
Octave functions or if I'd have to write such a function myself.

Oh, and my surface is integrable, which means it's almost continuous.
;-) It's probably also as smooth as you could want it, but it's very
wavy. It is, in fact, a solution of the nonlinear shallow water wave
equations, without shocks.
