Of all the purposes we’ve seen the iPad used for, 3D models are kind of a novelty. Interactive Fabrication released a software tool for “gestural sculpting” which uses the iPad as a multitouch-based remote controller. The software renders 3D models on a Mac, the iPad is used for touch controls up to 5 fingers.

TUAW reports:

As you can see, the iPad works as a controller for the app running on the MacBook, and not only is touchscreen information passed on to the 3D modeling program (I like that multitouch works as well, so you can mold five different points in the sculpture at once), but accelerometer information is also passed across, so tilting the iPad around also tilts the onscreen view.

You can even pass the information along to a 3D printer and get a physical result of what you’ve been creating with the iPad and OS X. The developers released the tool as open source code, it’s available on their website. Check out the video below. Very cool.
