Algorithm for generating a 3D Hilbert space-filling curve in Python

Question

I\'d like to map points in a RGB color cube to a one-dimensional list in Python, in a way that makes the list of colors look nice and continuous.

I believe using a 3

Answer 1

What's frequently used in engineering practice is not strictly Hilbert (Peano) curves - it's Morton code.

Much easier to compute.
