This is cool!

Any tips for an app to use on iOS to capture the necessary .ply data?

Scaniverse is a great app by Niantic that can do this on-device, but it isn't very customizable and can't export its raw scanning data (exported .plys do not have the data this editor requires).

PolyCam I think is the most popular?

Polycam or Scaniverse
