Check Azure Spatial Anchors, "Across augmented reality (AR) platforms, “anchors” are a common frame of reference for enabling multiple users to place digital content in the same physical location, where it can be seen on different devices in the same position and orientation relative to the environment. With Azure Spatial Anchors, you can add anchor persistence and permissions, and then connect anchors in your application so that your users can find nearby content." https://azure.microsoft.com/en-us/services/spatial-anchors/ https://azure.microsoft.com/en-us/services/spatial-anchors/
