1 # Mouse Tracker for Cubism
3 A library that tracks mouse cursor location and microphone input and
4 converts them into Live2D® Cubism SDK parameters.
6 This is a spin-off project from [Facial Landmarks for Cubism](https://github.com/adrianiainlam/facial-landmarks-for-cubism).
7 The objective is to provide similar functionality, but requiring much
8 less CPU load, which can be critical if the processor does not support
9 AVX instructions. It also does not require the use of a dataset which
10 restricts commercial use, and it does not require a webcam.
12 *Disclaimer: This library is designed for use with the Live2D® Cubism SDK.
13 It is not part of the SDK itself, and is not affiliated in any way with Live2D
14 Inc. The Live2D® Cubism SDK belongs solely to Live2D Inc. You will need to
15 agree to Live2D Inc.'s license agreements to use the Live2D® Cubism SDK.*

20 ## Supporting environments
22 This library is designed for Linux (or other *nix systems) with X11 and
25 I have made use of one C++17 library (`<filesystem>`)
26 in the example program, but it should be straightforward to change this
27 if you don't have C++17 support.
31 1. Install dependencies.
33 You will require a recent C/C++ compiler, `make`, `patch`, CMake >= 3.16,
34 libxdo, and PulseAudio. To compile the example
35 program you will also require the OpenGL library (and its dev headers)
36 among other libraries required for the example program. The libraries I
37 had to install (this list may not be exhaustive) are:
39 libxdo-dev libpulse-dev libgl1-mesa-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev libglu1-mesa-dev
41 2. Clone this repository including its submodule (editline)
43 git clone --recurse-submodules https://github.com/adrianiainlam/mouse-tracker-for-cubism.git
45 3. To build the library only: (Skip this step if you want to build the example
46 program. It will be done automatically.)
48 cd <path of the git repo>
51 To build the example program:
53 4. Download "Cubism 4 SDK for Native R1" from the Live2D website:
54 <https://www.live2d.com/en/download/cubism-sdk/download-native/>.
56 Extract the archive -- put the "CubismSdkForNative-4-r.1" folder under
57 the "example" folder of this repo.
59 Note: The Cubism SDK is the property of Live2D and is not part of this
60 project. You must agree to Live2D's license agreements to use it.
63 "example/CubismSdkForNative-4-r.1/Samples/OpenGL/thirdParty/scripts"
68 6. Go back to the "example" directory and run
72 Note: I have observed that sometimes, on the first build, a failure
73 will be reported, such as:
75 [ 98%] Completed 'editline'
76 [ 98%] Built target editline
77 Makefile:149: recipe for target 'all' failed
78 make: *** [all] Error 2
80 I have no idea why, but seems like running build.sh again solves the
81 issue. Please open an issue / contact me if not.
83 7. Now try running the example program. From the "example" directory:
85 cd ./demo_build/build/make_gcc/bin/Demo/
89 ## Command-line arguments for the example program
91 Most command-line arguments are to control the Cubism side of the program.
92 Only one argument (`--config`) is used to specify the configuration file
93 for the Facial Landmarks for Cubism library.
95 * `--window-width`, `-W`: Specify the window width
96 * `--window-height`, `-H`: Specify the window height
97 * `--window-title`, `-t`: Specify the window title
98 * `--root-dir`, `-d`: The directory at which the "Resources" folder will
99 be found. This is where the model data will be located.
100 * `--scale-factor`, `-f`: How the model should be scaled
101 * `--translate-x`, `-x`: Horizontal translation of the model within the
103 * `--translate-y`, `-y`: Vertical translation of the model within the window
104 * `--model`, `-m`: Name of the model to be used. This must be located inside
105 the "Resources" folder.
106 * `--config`, `-c`: Path to the configuration file for the Mouse Tracker
107 for Cubism library. See below for more details.
109 ## Configuration file
111 There are fewer tweakable parameters compared to the Facial Landmarks
112 library, but I have still kept the configuration file to allow some
113 customization. The file
114 "config.txt" lists and documents all parameters and their default values.
115 You can change the values there and pass it to the example program using
116 the `-c` argument. If using the library directly, the path to this file
117 should be passed to the constructor (or pass an empty string to use
122 The library itself is provided under the MIT license. By "the library itself"
123 I refer to the following files that I have provided under this repo:
125 * src/mouse_cursor_tracker.cpp
126 * include/mouse_cursor_tracker.cpp
127 * and if you decide to build the binary for the library, the resulting
128 binary file (typically build/libMouseTrackerForCubism.a)
130 The license text can be found in LICENSE-MIT.txt, and also at the top of
131 the .cpp and .h files.
133 This library depends on "editline" which is included here as a git
134 submodule. The fork used here was originally written by Simmule
135 Turner and Rick Salz, made available under the Spencer License 94,
136 now maintained by Joachim Wiberg. See "lib/editline/LICENSE" for more
139 (Note: An earlier version of this library linked to GNU Readline as
140 a dependency. I have made a mistake and assumed GNU Readline was LGPL,
141 when in fact it was GPL. This has been corrected within 24 hours, by
142 replacing GNU Readline with editline instead. I apologize to the
143 copyright holders of GNU Readline.)
145 The example program is a patched version of the sample program provided
146 by Live2D (because there's really no point in reinventing the wheel),
147 and as such, as per the licensing restrictions by Live2D, is still the
150 The patch file (example/demo.patch) contains lines showing additions by
151 me, as well as deleted lines and unchanged lines for context. The deleted
152 and unchanged lines are obviously still owned by Live2D. For my additions,
153 where substantial enough for me to claim ownership, I release them under
154 the Do What the Fuck You Want to Public License, version 2. The full license
155 text can be found in LICENSE-WTFPL.txt.
157 All other files not mentioned above that I have provided in this repo
158 (i.e. not downloaded and placed here by you), *excluding* the two license
159 documents and files generated by Git, are also released under the Do What
160 the Fuck You Want to Public License, version 2, whose full license text
161 can be found in LICENSE-WTFPL.txt.
163 In order to use example program, or in any other way use this library

168 This is not a license requirement, but if you find my library useful,
169 I'd love to hear from you! Send me an email at spam(at)adrianiainlam.tk --
170 replacing "spam" with the name of this repo :).
174 Contributions welcome! This is only a hobby weekend project so I don't
175 really have many environments to test it on. Feel free to submit
176 issues or pull requests on GitHub, or send questions or patches to me
177 (see my email address above) if you prefer email. Thanks :)
