Most traditional 3D Hilbert encoding and decoding algorithms work on order-wise manner and are not aware of the difference between different input data and spend equivalent computing costs on them, thus resulting in a low efficiency.

WebThe figure above shows the first three iterations of the Hilbert curve in two ( n=2) dimensions. The p=1 iteration is shown in red, p=2 in blue, and p=3 in black. For the p=3 iteration, distances, h, along the curve are labeled from 0 to 63 (i.e. from 0 to 2^ {n p}-1 ).

WebMar 8, 2016 · I made a simple driver routine, that takes 3 values as arguments from the command line and passes them to a Hilbert curve encode, decode routines. More precisely, I can't decode back the original coordinates (x,y,z). One of my problems was to understand what the variable nbits is doing. I assume it is the size of the encoded Hilbert value.
