How to get started
git clone [email protected]:emilk/wfc.git
cd wfc
./main.cpp
./main.cpp starts with a shell script that downloads dependencies, build, links, and finally runs the program.
This works on Mac and Linux.
Requirements
C++14. Nothing more, really.
All required third-party libraries are included or downloaded by running ./main.cpp. These are:
- https://github.com/emilk/configuru (
.cfgloading) - https://github.com/emilk/emilib (small helpers for looping and string formating)
- https://github.com/emilk/loguru (logging and asserts)
- https://github.com/nothings/stb (image read/write)
- http://www.jonolick.com/home/gif-writer (write gif files)
Performance
The sample configuration finishes 25% faster than the original version (50 vs 40 seconds).
Tested on a Linux VM, speed may be better on an installed distribution.
Limitations
This port supports everything in https://github.com/mxgmn/WaveFunctionCollapse (as of October 2016), though with slightly different input (.cfg files over .xml, for instance).
The code is not optimized nor well-documented. It could also do with some further cleanup.
