This is nothing new- Google's "Cardboard Camera" app has been around for a few years and does almost exactly this same thing. https://play.google.com/store/apps/details?id=com.google.vr....

This looks like it is actually creating a 3d model. The app you linked to I think just stitches together photos into something closer to street view. It's not actually 3d, it just looks 3d because you have enough photos to cover the whole field of vision.

They don't do a 3d model, but it is a real stereo image. There's a bit more info in their docs: https://developers.google.com/vr/concepts/cardboard-camera-v...

> it is a real stereo image

Until you look down. Or until you have a different eye distance than average. Or you try to move a bit and there are things close enough to make you dizzy.

Cardboard didn't need any of those fancy things, of course. It was bad enough with abysmal latency.
