 This an implementation of very primitive tile-based wave function collapse.
 It uses tiles to generate an image, similar to this:

 ![Demo of the program](demo/demo.png)
 
 It generates the tiles as ppm, then generates the image, similar to the demo image as ppm. There is a script to turn the ppm files into png using imagemagick.

+### How it works
+
+There are two programs, the first one generates the tiles and a special little file which includes the information
+if a tile should connect to another tile. The tiles are specified as bitmaps, their symmetry type, and on which sides it connects.
+And the program generates every tile and all of its rotations as ppm files.
+
+The other program reads the ppm tiles and the tile-info file (tiles.bin) and it creates the tilemap.
+Using the tile-info file it internally creates a table of bit masks to apply to the neighbors of collapsed tiles.
+Other than that it functions very similar to a normal a normal simple tiled model
