Save AR object transform to file or database?

Is there a tutorial on saving a placed AR object's transform to file or database?

Basically I'm looking for a way to place models around in a space and save it so the next/new session, or another person to view the models and their placements.

So I'm guessing using GPS & wifi for placements. I know that method isn't entirely precise, it could be a meter off in placement. I'm also thinking of using image tracking as object placement for precise placements. The images would be taken during run time and not preset in a reference library.

Thanks.

 

Where do you want to store it? Locally or on a server? Or just send it to a person in the same room?
Locally you can just do something with this https://docs.unity3d.com/ScriptReference/PlayerPrefs.Save.html
For a server, I've been trying Azure Storage and found that they have a unity plugin that makes it quite easy to store some data on a server.
For the last option, you need some multiplayer system. I found Photon very easy to implement and use.

 

Thanks.
