Wave function collapse (wfc for short) is an algorithm used in game development to procedurally generate contents such as images or 3D models. It's especially exciting for game designers, letting us draw our ideas instead of hand coding them. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Wave Function Collapse. This may reduce the possibilities for other locations around that initial one, or, depending on the tileset, even completely determine what tiles we must pick in some places. It is most commonly used to create images, but is also capable of building towns, skateparks, and terrible poetry. Are you sure you want to create this branch?

The Wave Function Collapse algorithm is a heuristic for generating tiled images.. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. This works until a cell is reduced down to 1 possibility, and because there is no recursion, that cell that just collapsed by proxy did not reduce the possibilities of neighbouring cells.

Observation: Find a wave element with the minimal nonzero entropy. All I did was create a bunch of grid objects (contained in a whole sudoku board object) with lists containing numbers 1-9, which represented the possible numbers that can be placed in a certain 'cell' or 'pixel' in that grid. Like how to implement rules and how to use those rules to do constraint propagation and such. Ultimately, you can make the argument that the WFC doesn't need to operate . The algorithm begins with a collection of equal sized image blocks and randomly places them, one at a time, within a grid subject to the tiling constraint and an entropy constraint, and it wraps (the top row of blocks in the grid is treated as adjacent to the bottom row of blocks, and similarly the left and right . A tag already exists with the provided branch name. Wave Function Collapse is a procedural content generation algorithm that uses an extension of constraint solving. Furthermore, the Wave Function Collapse Algorithm operates on a matrix of cells, which translates really well to image processing but not so well to freeform 3d structures. All the algorithm guarantees is that there is a consistent path or arc between all of the values. A tag already exists with the provided branch name.
