Integrating visage|SDK into Unity project

visage|SDK allows easy integration with Unity 3D game engine using VisageTrackerUnityPlugin and VisageAnalyserUnityPlugin, wrappers that expose VisageTracker's and VisageFaceAnalyser's functionalities for use in managed programming language such as C#.
In order to use visage|SDK in your own Unity project, libraries and selected data files need to be included. Unity sample application VisageTrackerUnityDemo is provided in visage|SDK as a ready-to-build project with all necessary dependencies and can be used as a reference.

Following steps are required to integrate visage|SDK in your own project:

Pre-build step:

Following libraries need to be added to the project:
- VisageTrackerUnityPlugin.jslib (located in www/lib folder)
- VisageAnalyserUnityPlugin.jslib (located in www/lib folder)
Following files and folders (located in www/lib) need to be copied to the project's assets:
- tracker configuration file (e.g. Head Tracker.cfg)
- neural net configuration file (i.e. NeuralNet.cfg)
license key file

Post-build step:

The following files need to be copied to the same folder as the index.html file:
- visageAnalysisData.data (located in www/lib folder)
- visageAnalysisData.js (located in www/lib folder)
- visageSDK.data (located in www/lib folder)
- visageSDK.wasm (located in www/lib folder)
- visageSDK.js (located in www/lib folder)

Modify index.html output file to expose unityInstance to the global variable unityGame:


<body>
    <script>
    ...
    var unityGame;
    var script = document.createElement("script");
    script.src = loaderUrl;
    script.onload = () => {
      createUnityInstance(canvas, config, (progress) => {
        progressBarFull.style.width = 100 * progress + "%";
      }).then((unityInstance) => {
        loadingBar.style.display = "none";
        unityGame = unityInstance;
        fullscreenButton.onclick = () => {
          unityInstance.SetFullscreen(1);
        };
      }).catch((message) => {
        alert(message);
      });
    };
    document.body.appendChild(script);
    </script>
</body>
