Book excerpt: "The Animator's Reference Book" serves as a visual reference guide for animators to show common human motion. It is an update of a classic series of reference books by Eadweard Muybridge. Although these books are generally heralded as the best reference books available, Muybridge's photographs were taken more than 100 years ago at the dawn of photography and are of poor quality. This updated book is designed specifically for the animator. It will help animators understand how to create better animation by studying actual motion. It will also serve as a valuable reference for game developers who wish to incorporate realistic human motion into their game design. In addition to human motion reference, this book will also contain instruction and tips for animating characters.
