That is an interesting idea. However, I see the method (or at least some implementations of it) are covered by a patent.
I don't look at patents. Everything I've described is either my own (re-)invention or taken from the 1981 paper "Multidimensional Range Search in Dynamically Balanced Trees" by Tropf and Herzog that is linked from the Z-curve Wikipedia page.
Can something that is published by Tropf 1981 be patented by Tropf 2004? -- Interval Container Library [Boost.Icl] http://www.joachim-faulhaber.de
