The basic approach is to convert a n-dimensional point into 1-dimensional Hilbert space-filling curve. Passing this algorithm as a lambda to std::sort allows to sort n-dimensional points in a C++ container.

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. floaters years after cataract surgery
