The food scans demo ("Interactivity" examples section) is incredible. Especially Mel's Steak Sandwich looking into the holes in the bread.

The performance seems amazingly good for the apparent level of detail, even on my integrated graphics laptop. Where is this technique most commonly used today?

There's a community of people passionate about scanning all short stuff with handheld devices, drones... Tipatat let us generously use his food scans for the demo. I also enjoy kotohibi flower scans: https://superspl.at/user?id=kotohibi

Wow what kind of device do I need to make my own?

The food scans are just photos from a Pixel phone processed with postshot (https://www.jawset.com/) to generate the splats

Out of interest, to what extent do splats recorded in this manner have reliable/measurable dimensions?

They are not reliable at all unless paired with some physical measurements (Lidar, or a known size object in the scene).

Probably an interesting use for a pretrained model to estimate scale based on common items seen in scenes (cars, doorframes, trees, etc…)

I'm sure it's not cutting edge, but the app "scaniverse" generates some very nice splats just by you waving your phone around an object for a minute or so.

Yes there are several phone apps to generate splats. Also Luma 3D capture.

And the transfer size for that level of detail isn't that bad, either - only around 80MB. (Not being sarcastic, it's really neat.)

Yeah. And some of the individual scans like Clams and Caviar or Pad Thai are < 2MB.
