How to extrude light

By Rain Noe - September 15, 2010

These amazing images were made using an iPad, long-exposure photography and some clever programming. A collaboration between UK-based design consultancy Berg and Dentsu London yielded a brilliant way to "extrude" light into visual forms:

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.

Still don't get it? Hit the jump for a demonstrative video.

Pretty amazing concept. It took about 30-40 seconds to get the above photo, I wish it was faster but maybe it's my phone (iphone 3G)

I used to make long exposure photos painting with light using a flashlight. This is taking it to the next level ! :)

DUUUDE! This is badass! The actual explanation of how this was done left me a little disappointed though. From the pictures alone, I thought there was some cool new 3D displays we were going to learn about.
