From the Google Blog and Google Code Blog:
A digital interface needs to be familiar enough to be intuitive, while simultaneously taking advantage of the lack of constraints in a virtual space. In this case, we imagined something that looks like the shelves in your living room, but is also capable of showcasing the huge number of titles available online—many more than fit on a traditional shelf. With this in mind, we designed a digital bookcase that’s an infinite 3D helix. You can spin it side-to-side and up and down with your mouse. It holds 3D models of more than 10,000 titles from Google Books.
The books are organized into 28 subjects. To choose a subject, click the subject button near the top of your screen when viewing the bookcase. The camera then flies to that subject. Clicking on a book
pulls it off the shelf and brings it to the front and center of the screen. Click on the high-resolution cover and the book will open to a page with title and author information as well as a short synopsis, provided by the Google Books API. All of the visuals are rendered with
WebGL, a technology in Google Chrome and other modern browsers that enables fast, hardware-accelerated 3D graphics right in the browser, without the need for a plug-in.
Bookworms using a modern browser can try the WebGL Bookcase today. We recommend using Google Chrome and a fast computer with a powerful graphics card. Even with new hardware, this interface is experimental and may not work on some machines.
If you want a quick look here at the experimental “bookcase” here’s a 38 second video that’s also embedded in the blog post.
