# Facial Landmarks for Cubism
-A library that extracts facial landmarks from a webcam feed and converts them
+A library that extracts facial landmarks from a webcam feed (computed by [OpenSeeFace](https://github.com/emilianavt/OpenSeeFace)) and converts them
into Live2D® Cubism SDK parameters.
*Disclaimer: This library is designed for use with the Live2D® Cubism SDK.

+## Old version using dlib
+The old version using dlib is no longer actively maintained, but if
+you want to use it, you can get it on the [dlib-stable branch](https://github.com/adrianiainlam/facial-landmarks-for-cubism/tree/dlib-stable).
+
+## Spin-off: Mouse Tracking for Cubism
+
+An alternative version using mouse cursor tracking and audio based lip
+syncing instead of face tracking is available at
+<https://github.com/adrianiainlam/mouse-tracker-for-cubism>.
+
+The main advantage is a much lower CPU load.
## Supporting environments
This library was developed and tested only on Ubuntu 18.04 using GCC 7.5.0.
-However I don't think I've used anything that prevents it from being
-cross-platform compatible -- it should still work as long as you have a
-recent C/C++ compiler. (The library should only require C++11. The Cubism
+
+Currently it only supports Unix-like environments, as I am using
+`<sys/socket.h>` etc to communicate with OpenSeeFace. If there is demand
+for it, I can try to make it work on Windows as well (contributions
+welcome).
+
+The library should only require C++11. The Cubism
SDK requires C++14. I have made use of one C++17 library (`<filesystem>`)
in the example program, but it should be straightforward to change this
if you don't have C++17 support.
-I have provided some shell scripts for convenience when building. In an
-environment without a `/bin/sh` shell you may have to run the commands
-manually. Hereafter, all build instructions will assume a Linux environment
-where a shell is available.
-
-If your CPU does not support AVX instructions you may want to edit the
-relevant build scripts to remove the `-D USE_AVX_INSTRUCTIONS=1` variable
-(or change it the SSE3 etc). However there could be a penalty in performance.

-4. You will require a facial landmark dataset to use with dlib. I have
- downloaded mine from
- <http://dlib.net/files/shape_predictor_68_face_landmarks.dat.bz2>.
- Extract the file and edit the "config.txt" file to point to the
- path to this file.

- Note: The license for this dataset excludes commercial use. If you want
- to use this library in a commercial product you will need to obtain a
- dataset in some other way.

To build the example program:
-5. Copy the extracted dlib dataset from step 4 to the "example" folder
- of this repo.

-6. Download "Cubism 4 SDK for Native R1" from the Live2D website:

* `--model`, `-m`: Name of the model to be used. This must be located inside
the "Resources" folder.
+ * `--old-param-id`, `-o`: If set to 1, translate new (Cubism 3+) parameter
+ IDs to old (Cubism 2.1) IDs. This is necessary, for example, for

* `--config`, `-c`: Path to the configuration file for the Facial Landmarks
for Cubism library. See below for more details.
I have decided to make pretty much every parameter tweakable. The file
"config.txt" lists and documents all parameters and their default values.
You can change the values there and pass it to the example program using
