DeBroglie is a C# library implementing the Wave Function Collapse algorithm with support for additional non-local constraints, and other useful features.

Wave Function Collapse (WFC) is an constraint-based algorithm for generating new images that are locally similar to a sample bitmap. It can also operate on tilesets, generating tilemaps where the tile adjacency fits a specification.

Unlike the original WFC implementation, De Broglie has full backtracking support, so can solve arbitrarily complicated sets of constraints. It is still optimized towards local constraints.

• "Overlapped" model implementation of WFC
• Non-local constraints allow you to specify other desired properties of the result
• Backtracking support - the original WFC implementation immediately give up when a contradiction occurs.
• supports 2d tiles, hexs, and 3d voxels
