The description from the book’s product page reads:
The book will also include an introduction to 3D engines — a topic that could fill entire book on its own. Currently, the only browser which supports WebGL on Android is Fennec, a mobile version of Firefox, so the book may have readers develop their own engine using the canvas element.
The planned release date for the book is November 15th, 2011.
