The aim of this book is to examine the geometry of our world and, by blending theory with a variety of every-day examples, to stimulate the imagination of the readers and develop their geometric intuition. It tries to recapture the excitement that surrounded geometry during the Renaissance as the development of perspective drawing gathered pace, or more recently as engineers sought to show that all the world was a machine. The same excitement is here still, as enquiring minds today puzzle over a random-dot stereogram or the interpretation of an image painstakingly transmitted from Jupiter. The book will give a solid foundation for a variety of undergraduate courses, to provide a basis for a geometric component of graduate teacher training, and to provide background for those who work in computer graphics and scene analysis. It begins with a self-contained development of the geometry of extended Euclidean space. This framework is then used to systematically clarify and develop the art of perspective drawing and its converse discipline of scene analysis and to analyze the behavior of bar-and-joint mechanisms and hinged-panel mechanisms. Spherical polyhedra are introduced and scene analysis is applied to drawings of these and associated objects. The book concludes by showing how a natural relaxation of the axioms developed in the early chapters leads to the concept of a matroid and briefly examines some of the attractive properties of these natural structures.

Multiple View Geometry in Computer Vision

A basic problem in computer vision is to understand the structure of a real world scene given several images of it. Techniques for solving this problem are taken from projective geometry and photogrammetry. Here, the authors cover the geometric principles and their algebraic representation in terms of camera projection matrices, the fundamental matrix and the trifocal tensor. The theory and methods of computation of these entities are discussed with real examples, as is their use in the reconstruction of scenes from multiple images. The new edition features an extended introduction covering the key ideas in the book (which itself has been updated with additional examples and appendices) and significant new results which have appeared since the first edition. Comprehensive background material is provided, so readers familiar with linear algebra and basic numerical methods can understand the projective geometry and estimation algorithms presented, and implement the algorithms directly from the book.

Distinguished Figures in Descriptive Geometry and Its Applications for Mechanism Science

From the Middle Ages to the 17th Century

This book consists of chapters that focus specifically on single figures that worked on Descriptive Geometry and also in Mechanisms Sciences and contain biographical notes, a survey of their work and their achievements, together with a modern interpretation of their legacy. Since Vitruvius in ancient times, and with Brunelleschi in the Renaissance, the two disciplines began to share a common direction which, over the centuries, took shape through less well-known figures until the more recent times in which Gaspard Monge worked. Over the years, a gap has been created between Descriptive Geometry and Mechanism Science, which now appear to belong to different worlds. In reality, however, there is a very close relationship between the two disciplines, with a link based on extremely solid foundations. Without the theoretical foundations of Geometry it would not be possible to draw and design mechanical parts such as gears, while in Kinematics it would be less easy to design and predict the reciprocal movements of parts in a complex mechanical assembly.

Picturing Space, Displacing Bodies

In Picturing Space, Displacing Bodies, Lyle Massey argues that we can only learn how and why certain kinds of spatial representation prevailed over others by carefully considering how Renaissance artists and theorists interpreted perspective. Combining detailed historical studies with broad theoretical and philosophical investigations, this book challenges basic assumptions about the way early modern artists and theorists represented their relationship to the visible world and how they understood these representations. By analyzing technical feats such as anamorphosis (the perspectival distortion of an object to make it viewable only from a certain angle), drawing machines, and printed diagrams, each chapter highlights the moments when perspective theorists failed to unite a singular, ideal viewpoint with the artist&’s or viewer&’s viewpoint or were unsuccessful at conjoining fictive and lived space.Showing how these &“failures&” were subsequently incorporated rather than rejected by perspective theorists, the book presents an important reassessment of the standard view of Renaissance perspective. While many scholars have maintained that perspective rationalized the relationships among optics, space, and painting, Picturing Space, Displacing Bodies asserts instead that Renaissance and early modern theorists often revealed a disjunction between geometrical ideals and practical applications. In some cases, they not only identified but also exploited these discrepancies. This discussion of perspective shows that the painter&’s geometry did not always conform to the explicitly rational, Cartesian formula that so many have assumed, nor did it historically unfold according to a standard account of scientific development.

Machine Interpretation of Line Drawings

This book solves a long-standing problem in computer vision, the interpretation of line drawings and, in doing so answers many of the concerns raised by this problem, particularly with regard to errors in the placement of lines and vertices in the images. Sugihara presents a computational mechanism that functionally mimics human perception in being able to generate three-dimensional descriptions of objects from two-dimensional line drawings. The objects considered are polyhedrons or solid objects bounded by planar faces, and the line drawings are single-view pictures of these objects. Sugihara's mechanism has several potential applications. It can facilitate man-machine communication by extracting object structures automatically from pictures drawn by a designer, which can be particularly useful in the computer-aided design of geometric objects, such as mechanical parts and buildings. It can also be used in the intermediate stage of computer vision systems used to obtain and analyze images in the outside world. The computational mechanism itself is not accompanied by a large database but is composed of several simple procedures based on linear algebra and combinatorial theory. Contents:Introduction. Candidates for Spatial Interpretation. Discrimination between Correct and Incorrect Pictures. Correctness of HiddenPart-Drawn Pictures. Algebraic Structures of Line Drawings. Combinatorial Structures of Line Drawings. Overcoming Superstrictness. Algorithmic Aspects of Generic Reconstructibility. Specification of Unique Shapes. Recovery of Shape from Surface Information. Polyhedrons and Rigidity. Kokichi Sugihara is Professor in the Department of Mathematical Engineering and instrumentation Physics, Faculty of Engineering, the University of Tokyo, Tokyo, Japan. Machine interpretation of Line Drawingsis included in The MIT Press Series in Artificial Intelligence, edited by Patrick Henry Winston and Michael Brady.

Drawing on the Air

In the New York Times Michael Kimmelman called them "sleek, whimsical contraptions in a modernist mode"; the Basler Zeitung termed them "net-like structures . . . like hedgehogs or serpents." The kinetic sculptures of Tim Prentice create a novel geometry of air and light. Concentrating on movement rather than object, Prentice harnesses natural elements into his art machines-delicate structures that walk the tightrope between order and chaos, control and serendipity, understated technique and extravagant wonder. Prentice purposely circumscribes the artist's prerogatives, distilling the power of wind and sun into an ever-changing dance of light and shadow. These understated, subtle inventions provide endless distraction, delighting the child in all of us. Drawing on Air offers a many-sided vision of the kinetic sculptor and his works. An essay by Nicholas Fox Weber introduces the artist and his work, while a chapter on "Mechanics" explains some of the physical principles underlying Prentice's whimsical sculptures. Photographs of works-in-progress, principal public commissions as well as occasional pieces created for casual amusement are punctuated by the artist's mordant, sometimes mischievous comments. "Prentice's sculptures . . .are about fluid movement and change, reminding us that everything is in flux. . . . Wonders of engineering, they create evanescent drawings in thin air." -Michael Amy, Art in America "What is grand in these sculptures is the sense of immensity created by their movements, a sense resonant with our most pleasurable apprehensions of land, sea, and sky." -Elaine Bleakney, Sculpture "These refined sculptures are never ponderous, plump or boring but constantly and slowly transforming themselves as though imbued by perpetuum mobile." -Karen Gerig, Basler Zeitung Experiencing Tim Prentice's work is like taking a ride on a roller coaster" -Catalog of the Connecticut Biennial
