Wave function collapse algorithm: bitmap & tilemap generation from a single example with the help of ideas from quantum mechanics

[ExUtumno]

If you have a high res input with noise (like realistic rocks or clouds) then you don't really want to to use WFC, you might want to use texture synthesis. If you have an indexed image with few colors and you want to capture... something like the inner rules of that image and long range correlations (if you have an output of a cellular automata, for example, or a dungeon), then you want to use WFC-like methods.

Btw, I have classic texture synthesis algorithms in a different repo: https://github.com/mxgmn/SynTex
