Programmatically controlling USDZ QuickLook objects' initial state in Safari?

Safari utilizes the system wide AR Quick Look features to render linked USDZ files (as seen at https://developer.apple.com/arkit/gallery/ ).


Are there any options other than rel="ar" that could be used to initialize the view? I'm looking for ways to display AR content depending on the user's location and would interpret location data into coordinates and sizing values that could be used when calling the file. As in <a href="3dObject.usdz" rel="ar" data-transform3d="45,0,90" data-transformScale="2">. Obviously, calling a container via JavaScript would be more flexible, but if AR Quick Look has any hooks for providing initial state settings up front, this would be fine for my case.


Thanks for any pointers; AR in the browser context is still at such an early stage, but so interesting 🙂
