If you call yourself a computer graphics professional but aren"t sure of the meaning of cukaloris, Lambertian reflection, or umbra, you might want to pick up a copy of Visual Effects in a Digital World: A Comprehensive Glossary of over 7,000 Visual Effects Terms. Educational, fun, and historically fascinating, this is one of those books that every pixel monkey should have on his or her shelf. If you"ve ever wondered what, exactly, rotoscope means (it has three different meanings) or what to eat with a "metaball," this book is for you. Chock full of interesting tidbits and a 32-page color gallery of examples, this is probably one of the more interesting technical dictionaries you"ll ever have the pleasure of looking through. Perhaps you know the difference between an array and an Arri, but the producer you"re trying to explain it to is clueless. The clear, concise definitions listed here can help elucidate these terms and others so that even the most dense suit will, if not understand, at least feel like you must know what you"re talking about. It"s one thing to be able to know what buttons to push, but something else entirely to be able to stump your friends with the meaning of arcane terms like Lindenmayer System or octrees. Everyone knows you"re a geek. Now you can prove it. --Mike Caputo
