This sample demonstrates tracking via the Track widget. It works using geolocation functionality which accesses the geographic location of the tracking device and displays it in the SceneView. Since this sample may be accessed on a desktop, it was written with hardcoded coordinate locations to simulate tracking. The view rotates according to the direction where the tracked device is heading towards. A third party library is referenced for the geolocation API reference.
There are security considerations to be taken into account when working with geolocation. The Track widget is not supported on insecure origins. To use it, switch your application to a secure origin, such as HTTPS. Note that localhost is considered "potentially secure" and can be used for easy testing in browsers that supports Window.isSecureContext (currently Chrome and Firefox).
