i3D for iPhone and iPad 2 Brings 3D to 2D Displays With Face Tracking

i3D for iPad 2

3D  and iOS fans may remember Wen Duan‘s post about using the front-facing camera to achieve 3D on the iPad 2 and iPhone 4; you may be interested to know that you can now try it out for yourself if you have either of those devices. The app is called i3D and is available now for free on the Apple app store.

Before you go off and get it, it’s handy to know that it’s not a game. This is an interactive tech demo that lets you basically go through the same demos shown in the video that made the rounds last month. The idea here is that this could be used as middleware for game developers to bring 3D titles to iOS devices and have them play much the same as they do on the Nintendo 3DS.

One big question on my mind is how processor-intensive the face tracking is. The iPad 2 has proven to be pretty beefy when it comes to running software, but the iPhone 4 lags behind a generation on the chip side; how well would a 3D-intensive game run on top of this face tracking middle layer? With some luck, maybe we’ll find out soon.

Grab it and give it a whirl, then come back and let us know what you think in the comments!
