Calculate the Hilbert value of a point for use in a Hilbert R-Tree?

Question

I have an application where a Hilbert R-Tree (wikipedia) (citeseer) would seem to be an appropriate data structure. Specifically, it requires reasonably fast spatial querie

Answer 1

The code and java code above are fine for 2D data points. But for higher dimensions you may need to look at Jonathan Lawder's paper: J.K.Lawder. Calculation of Mappings Between One and n-dimensional Values Using the Hilbert Space-filling Curve.
