From the reviews: MATHEMATICAL REVIEWS In this book the authors have combined results from the classical parts of geometry with computational methods This results in a unique and fascinating blend which is shown to be useful for a variety of applications including robotics geometrical optics computer animation and geometric design. The contents of the book are visualized by a wealth of carefully chosen illustrations making the book a shear pleasure to read or even to just browse in. The book will help to bring the concepts and techniques of line geometry...to the attention of a wider audience.
