Extrude the Light: Britons Make 3D "Holograms" With The iPad


Making Future Magic: iPad light painting from Dentsu London on Vimeo.

I know you were hoping for some real “Help me, Obiwan Kenobi” stuff but this is basically a long exposure image created by moving an iPad along a surface as it “plays” the parts of a 3D image. The result? An image that seems to float in the air like magic.

First we create software models of three-dimensional typography, objects and animations. We render cross sections of these models, like a virtual CAT scan, making a series of outlines of slices of each form. We play these back on the surface of the iPad as movies, and drag the iPad through the air to extrude shapes captured in long exposure photographs. Each 3D form is itself a single frame of a 3D animation, so each long exposure still is only a single image in a composite stop frame animation.

Created by Dentsu London and BERG, this is essentially a big ad for their creative services but gosh if it isn’t neat.
