+The project uses the 'Museum' scenario wit a statue as described in the GS 005 documentation. In the figure below, a statue would be augmented with some AR contents (e.g. a nose label). For this, some World Trackables, Anchors and Links are created (left picture in the figure) and are placed in the Unity scene onto the correct position (right picture). The statue serves as a digital twin and won't be visible in a final application.
