Wave Function Collapse for Image Files

A rust library for generating images which are similar to other images. Similar is defined as both:

• strict locally similar: every small (typically 3x3) pattern in the output image appears somewhere in the input image.
• loose globally similar: the distribution of small patterns in the output image is roughly the same as the distribution of small patterns in the input image.

This is based on https://github.com/mxgmn/WaveFunctionCollapse

Examples

Simple

This example generates an output image which is similar to the input image.

Flowers

It's also possible to manually restrict the output to encode specific properties. In this example:

• The bottom row of patterns is set to be ground.
• A sprout pattern is placed in a random position along the bottom of the output.
• Ground patterns are forbidden from being automatically chosen.
• The flower pattern is forbidden to appear in the bottom few rows of output, to enforce a minimum height of flowers.
