WaveFunctionCollapse

Purpose: WaveFunctionCollapse generates bitmaps that are locally similar to an input bitmap.
Pattern matching: The output is constrained to contain only NxN pixel patterns found in the input.
Tilemap generation: The simple tiled model can be initialized with tiles and adjacency data instead of a sample bitmap.
Symmetry: A tile symmetry system can shorten adjacency lists for tilesets with symmetrical tiles.
Constraints: The algorithm supports constraints and can be combined with other generative algorithms or manual creation.
Higher dimensions: The README describes WFC models in higher dimensions, including voxel examples.
Integrations: The README lists adaptations for Unity, Unreal Engine 5, Godot 4, and Houdini.
Platforms: The project can be built from source with .NET Core for Windows, Linux, or macOS, and the README links to a browser version.
Limit: Generation can reach a contradiction and stop without producing output; determining whether a valid bitmap exists is described as NP-hard.
License: The software is under the MIT License; the license states that the provided image samples and tiles are not part of the software.
Release note: The v1.00 release page says Linux and macOS users should download source from the repository because the bundled release source uses a Windows-only System.Drawing library.
Input augmentation: The algorithm can optionally augment pattern data with rotations and reflections.
Possible failure: Generation can stop if propagation creates a contradiction, leaving no valid coefficients for a pixel.
Intended uses: The README describes the method as well suited to game level generation and pixel art, and less suited to large full-color textures.
