## What it is
A C# implementation of the Wave Function Collapse algorithm that generates bitmaps and tilemaps locally similar to a single example input, using an observation-propagation cycle inspired by quantum mechanics. It is the reference implementation that has been ported to many other languages.

## Use cases
- generate tilemaps from a single example tileset
- procedurally generate textures for a game
- create pixel art variations from one sample image
- generate dungeon or level layouts procedurally
- learn how the wave function collapse algorithm works

## When to choose
- you need procedural bitmap or tilemap generation constrained to patterns from a sample
- you want the canonical reference implementation of WFC
- you are building a game that needs locally-similar generated content

## When to avoid
- you need guaranteed contradiction-free generation with high performance
- you need true quantum computing or actual quantum mechanics simulation
- you need a non-C# implementation without porting

## Facets
- artifact type: library
- maturity: stable
- function: graphics, simulation, data-generation, image-processing
- domain: graphics, machine-learning
- platform: cross-platform, dotnet, c
- tags: procedural-generation, wave-function-collapse, tilemap-generation, constraint-solving, gamedev, game-development, algorithms
