For an upcoming project I am working on, I needed an augmented reality camera view that overlays location based data which users can interactive with. It also needed to have a radar in the top corner indicating where these locations where.
When I first looked at Augmented reality back in 2011, the main examples where based on an open source project called iPhoneARKit. I was looking for an updated version and found this little gem:
iOSARKit by Carlos Alonso. I actually spoke to Carlos who was very helpful and friendly.

I have made a few tweaks to this which can be found here : Burf GitHub
