3D scanning by dipping into a liquid
I expected they'd be either visually watching the changing contours of an opaque liquid, or somehow using refraction to get multiple visual angles of the same features, but…<p>…they're repeatedly dipping it, and using the volume displacement to reconstruct the shape. Amazing. The site is hammered right now so I can't get more details: anyone see how many dips are required to get the highest-detail models they show on the landing page?
