3D Graphics with OpenGL ES and M3G- P2

3D Graphics with OpenGL ES and M3G- P2:Mobile phones are the new vehicle for bringing interactive graphics technologies to consumers. Graphics that in the 1980s was only seen in industrial flight simulators and at the turn of the millennium in desktop PCs and game consoles is now in the hands of billions of people. This book is about the technology underpinnings of mobile threedimensional graphics, the newest and most rapidly advancing area of computer graphics. | x CONTENTS CHAPTER 11.
