3D sketching for 3D printing. How was this not possible before?

Considering augmented reality has been around for some time now, it’s surprising that a technology that allows creatives to draw 3D images, seen in mid-air through a pair of glasses, was only recently developed. Either way, the Gravity sketch tech, developed by four London-based students of the Royal College of Art in less than a year, is pretty genius, and comes equipped with a tablet and stylus that’s used to draw a 2D image, but appears as three-dimensional when wearing a pair of augmented reality glasses.

What’s great about this contraption is it allows people to do what comes natural, drawing on a 2D plane instead of in mid-air (which could take some getting used to). The tool allows its user to rotate the image using a dial, and is useful in quickly creating and showing others your ideas in a 3D space, which can then be sent to the printer to bring it a more tangible life.
