This Unity project contains a mobile AR App based on PiratesJustAR's tutorial YouTube series (https://www.youtube.com/playlist?list=PLKIKuXdn4ZMhwJmPnYI0e7Ixv94ZFPvEP), but reworked to work with ARFoundation so it works both on iOS and Android, using the same codebase. I also added the ability to place the portal and replace it elsewhere, using a placement indicator (reused after following https://www.youtube.com/watch?v=Ml2UakwRxjk&t=1534s by The Unity Workbench)
There's two ways you can install this app:
You can clone this repository and build it using Unity. In order to do this, open the project in Unity, select the scene you're trying to build and configure your target device in file -> build settings
If you don't feel like cloning the whole repo and building it, and you have an android device, you can try out the app by downloading the apk from https://github.com/NaelAwayes/ARFoudation-Portal/releases, and installing it on your device.
PiratesJustAR and The Unity Workbench for their awesome tutorials
Idean France for allowing time for me to make this PoC app.
