'Floating 3D printing' brings sci-fi-style projections closer

‘Optical trap display’ projects graphics into the air, where they are visible from all anglesWe still don ’t have flying cars, brain-computer interfaces, or an artificial intelligence (AI) you can hold a conversation with, but one classic science-fiction technology is on our doorstep: true 3D displays which are capable of projecting an image into “thin air”.Anew paper in the journal Nature reports a breakthrough from a group of researchers at Brigham Young University in Utah: the first creation of a “free-space volumetric display”, capable of reproducing full-colour graphics floating in the air, visible from all angles.Continue reading...
