The experimental project has been developed internally at Wargaming and uses “local cloud rendering” to achieve maximum quality and realistic experience for viewers. iPad is connected to PC like a 3D mouse, meanwhile PC does all rendering & sends that back to iPad as video. The AR experiences is based on ARKit for iOS and iPad sends its constant position/orientation to PC, in-game camera in World of Tanks on PC matches the iPad’s position/orientation and sends what it sees back to iPad as video. WoT skybox is made transparent, and the app controls what “slice” of the map in a replay the visitor is seeing at any time.
In its current state of development the World of Tanks AR Spectate experience works with replays only.
