my coworkers and i are guessing at what data defines an anchor. i tried searching but struggled to find anything helpful.
our best guess was a combination Triangular Irregular Networks (TIN), gps, magnetic compass direction and maybe elevation sensors.
is this documented anywhere? if not, can a definition or description be provided?
We don't expose the internal details of ARAnchor but Combine Motion Sensing and Scene Analysis provides an overview.
You'll also find references to VIO in ARKit WWDC sessions.
