I'm currently working on a client project that uses the Vuforia library paired with an array of iPad Pros to pull off this sort of AR-light effect. But Vuforia relies on a tracking marker, and it's a huge pain in the ass for us. The idea of using lower-level camera and inertia sensor data to perform tracking without a marker is something I didn't expect to see without a Tango-like cluster of depth sensors. Can't wait to try this out.
