The naive implementation is n^2 (with n being the number of gridpoints), and simply iterates over the coarsest grid, each time finding the matching points in the two others. That code's destined not to look to ugly (possibly helped with clever application of #zip or sth? dunno), but if you have stricter speed requirements...
