1. Introduction
ARWorldMap is a unique function of ARKit, which can save the data scanned by the user (such as planes, feature points, anchor points, etc.) so that the user can still restore the last saved data after exiting the application and reopening it. You can also upload the data to the server or send it to other users through the LAN, so that the other party can see the same AR information in the same environment, so as to achieve the sharing effect.
