Believe me, if Apple's camera could 3D scan larger stuff accurately at a good distance, Apple marketing would be shouting it from the rooftops and slapping a 500 Dollar or 1K premium on that phone.

Another question is whether those "IR dots" grow and overlap at a distance. The dot on your face might be 0.01 mm in radius. 10 feet away it might have grown to 0.1 mm and overlap with the other 30,000 dots. This may not allow accurate 3D scanning at all.

A lot depends on HOW the camera creates the dots. Is it shooting 30,000 IR individual photons into the real world. Or is this 1 IR lamp that has a grille with 30,000 holes in front of it?

Anything that can be a viable replacement to LIDAR scanners and such - very expensive - would be worth a lot of money.

So if Apple really has created a viable 3D scanner, why haven't they called it iScan3D and put out a 200 Dollar app that lets you scan stuff with it?
