Publisher's summary

I'm sitting in Gordon Wetzstein's lab at Stanford University with a hacked-together prototype of a head-mounted display strapped to my face, using a wireless Xbox controller to manipulate a series of 3-D models: a lion, a chessboard filled with chess pieces, an espresso machine, and so on. The images are fairly simple, run-of-the-mill models—the kind that anyone could download from the Internet. What is interesting, though, is what happens as I stare at the models, turning them with the controller so I can inspect them from different angles: I can focus on the different parts of the images at different depths as I would when gazing at something in real life, so when I look at, say, the chess pieces up close, those in the background look fuzzy, and vice versa when I focus on the pieces in the distance.
