If we're talking Swift frameworks, ModelIO (underrated) and ObjectCapture are certainly part of things.
That black box is Object Capture API, which takes a folder of images and outputs an USDZ (or OBJ) file. Model I/O isn’t necessary.
Kudos to Apple for releasing a photogrammetry pipeline that allows web and app developers to build tools like this, with zero knowledge of 3D reconstruction required.
I work in the same field, making a capture app for photogrammetry software
I think that the photogrammetry side of things, the "give me an object now" will shift towards mobile device camera apps.
It is only serverside now due to power requirements.
I just saw that you're from https://www.aboundlabs.com and metascan.ai Your scans look great! So how does your black box work?
