iOS multiplayer AR game is possible
With the development of AR technology, major technology companies have also invested in this field, developing their own AR software development kits, such as Google's ARCore, Apple's ARKit, etc. These software development kits are obtained from video in mobile devices. The coordinates of the real world, and then the amplifying object is superimposed on the coordinates, thereby combining the amplified object with the actual environment.
At the WWDC 2018 Developers Conference last year, Apple officially launched the ARKit 2.0 augmented reality platform and added several new features to it:
Improved face tracking effect;
More realistic rendering processing power;
3D control detection capability;
The ability of the object to persist;
Shareable multiplayer AR capabilities.
The "shareable multi-person AR capability" allows multiple users to simultaneously view and interact with the same AR scene using different devices. Each user sees a common virtual environment from their own perspective. It is this new capability that makes iOS multiplayer AR games possible.
Specifically, an iOS device running iOS 12 can connect to multiple devices via Wi-Fi, Bluetooth, or other means of sharing, thereby sharing the WorldMap established by one device with other devices. For example: Player A performs the initial scene setting first, and player B who joins the game can share the synchronization between the devices through player A's tracking data sharing. During the game, the phone uses a special algorithm to share WorldMap and real-time location information.
