The same technique used for Thom's face in the Radiohead "House of Cards" video. I'll walk you through setting up your projector and camera, and capturing images that can be decoded into a 3D point cloud using a Processing application.
I've included a lot of discussion about how to make this technique work, and the general theory behind it. The basic idea is:
1 Download ThreePhase
2 Rotate a projector clockwise to "portrait"
3 Project the included images in /patterns, taking a picture of each
4 Resize the photos and replace the example images in /img with them
