Is it possible to have persistent worlds using AR Foundation?

    Hello Everybody,

    I want to make an AR app where the 3D objects would "remember" their position between sessions inside a physical room.

    Does anyone know what is the status of support for Cloud Anchors and World Maps for AR Foundation?

    Is it possible to create a backend/server which would keep the position of 3D objects between sessions / App Usages? Or can an AR App itself hold the World Map of the room for future uses? If so would it work on iOS and Android?

    Is the info on this site up to date as of April 2020?

    https://blogs.unity3d.com/2018/12/18/unitys-handheld-ar-ecosystem-ar-foundation-arcore-and-arkit/

    Any info would be appreciated.

    Kind Regards

    @mr_kodjo WOW - thanks for this Idea - I would actually never have thought of that - looks very promising - I'll check it out and see if it works..

    @todds_unity Thank You very much for this info - but just to understand well - you recommend making two separate builds (iOS + Android) with two different approaches for coding persistent World Maps? So then would I have to get rid od AR Foundation approach completely? Or would it be possible/practical to use AR Foundation + ArKit / ARCore in the same app?

    Are there any plans on ARF side to unify approach to persistent AR?

    Google ARcore Team working on persistent cloud anchor, it's going to release soon. right now it's in development stage.

    From : https://developers.google.com/ar/develop/java/cloud-anchors/overview-android
    ===============================
    Note: We’re currently developing persistent Cloud Anchors, which can be resolved for much longer. Before making the feature broadly available, we’re looking for more developers to help us explore and test persistent Cloud Anchors in real world apps at scale.
