“If I take a scan of my face, the app asks ‘what does the image look like if I shine the light from the left side, what does it look like from the right side,‘ and so on. There’s one three-dimensional answer per pixel, and combining all those answers results in the full 3-D model,” said Schindler.
“There are professional, $40,000 3-D scanners out there; this won’t perform like those do, but for anything under $100, this is your best bet.”
