As a data structure, Hilbert paths are +useful because ordering along the curve preserves locality: points +that are close together along the curve are also close together in space. +The converse is often, but not always, true. The coloration +reflects this. + +https://en.wikipedia.org/wiki/Hilbert_curve + +Written by Jamie Zawinski; 2011. + </_description> +</screensaver> |
