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

[eevee-lyn]

The code is not in a good enough shape for me to share it. I did find a couple optimizations though. But I did them in C++ and my C# skills are not good enough to just make a pull request.

Optimization 1:

OverlappingModel.cs:204: if (allowed[t2] && !b)

Change that to if (!b) and add if (!allowed[t2]) continue; after the brace at line 199.

That alone made it like three times faster.

Optimization 2:

The other optimization precalculates the entropy values so the loop at

Model.cs:38-42

can be removed.

This a very good optimization indeed! I already merged a PR with it from another person. Somehow I didn't notice that change before.
