Photogrammetry (building 3D from 2D inputs—in this case several source images) is what my friend learned in the Navy to refer to as “FM technology”: “F’ing Magic.”
Side note: I know that saying “Time is a flat circle” is totally worn out… but, like, time is a flat circle, and what’s up with Adobe style-transfer demos showing the same (?) fishing village year after year? Seriously, compare 2013 to 2019. And what a super useless superpower I have in remembering such things. ¯\_(ツ)_/¯
