It definitely constructs a face, but how accurate is it? Would be interesting to see a measurement of error against a known result. Maybe try rendering an image of a 3d model of a face, then attempt to reconstruct it from the rendered image and measure the displacement from the original model.

Probably not. Apple specifically said that they've tested Face ID against masks (even Hollywood quality ones). Also, Face ID checks for user attention, so a static 3d-printed would not work. I wonder though if it worked if you put a mask over your face with eye cutouts? When the devices arrive I'm pretty sure some very clever people will try to tackle this problem, this should be interesting :)
Man are they good at marketing. They just knew this precise conversation would come up and created the perfect brief counter-argument preemptively ("hollywood quality masks").

I wonder whether this could be used to crack face id.

I tried it on a few Japanese faces; it basically gave them a Caucasian-looking side profile: big foreheads with over-hanging eyebrow ridges; big noses.
Completely unrecognizable after turning more than a few degrees from front view.
Which is not to flame the project---nice work!---but as a potential improvement for certain applications, it would be useful to simply have these details as parameters that could be interactively tweaked.
Being able to adjust the overall roundness of the face, and prominence of the chin/forehead/nose would probably go a long way.

If you look at the .obj model file that you can download you can see exactly how accurate it it. The mesh is dense and the detail is not. The detail that it does have however is very plausible.

right, but adding in fake eyeballs should do the trick.

Notably, the shape/depth of my nose is very, very wrong.
