wfc_generator

Wave function collapse algorithm

It's a wave function collapse algorithm implementation written inrust. There are 3 different input options. To run app use cargo run --release --wfc-generator Example bitmap: Produced bitmaps:

1. You can use manual input and specify, what kinds of tiles can be near in different directions to each other. You should change the data/tiles-data.txt file. The format is:

   tile id

   path_to_file rotation_of_texture(number from 0 to 3)

   8 lines with possible neibors in different directions un order: (-1,-1), (-1, 0), (-1, 1), (0, -1), (0, 1), (1, -1), (1, 0), (1, 1).

2. You can use simple-input and change data/simple-input.txt. It uses gates system. You have different connections between your tiles. If tiles can connect with each other you should write the same digit (gate type) for them to connect. Tiles are rotated, so you should specify each texture onle once with gates in format: path_to_texture gates in directions up,left,right,down.

3. You also can use graphical editor, to make a sample and then turn them into the actual data. Use cargo run --release --bin map-to-data

   Controls are:

   arrows -> cursor moving

   V -> on/off selection mode, makes action to the whole selected region

   Y -> copy color under the cursor

   P-> paste color

   N -> next color in palet

   L -> load from file (data/map.txt)

   S -> write to file

   T -> transform into the data for generation

   Method uses N=3 neiborhood.
