The shift from vector graphics which I prefer to raster and bit map technology has been incorporated. Many contemporary problems are introduced: Most issues of pattern recognition and image enhancement are beyond the scope of this book.

From Model to Screen

Difficult choices were undoubtedly encountered in selecting the material, but it seems that wisdom prevailed. Currently the market is being flooded with graphics instruction manuals that tend to be tied to the limited hardware and aims of personal computers.

These hastily produced books may be useful for specific examples and routines that apply to hardware and installations under consideration, but they do not have the broader range of applicability and methodical concern of the book under review here. The authors state, "The purpose of this book is to provide both a tutorial and a reference source for readers interested in the many aspects of modern interactive graphics: Project MUSE promotes the creation and dissemination of essential humanities and social science resources through collaboration with libraries, publishers, and scholars worldwide.

Forged from a partnership between a university press and a library, Project MUSE is a trusted part of the academic and scholarly community it serves.

No institutional affiliation. LOG IN. The design of the "system" amounts to throwing together such present-day items as inertial guidance "inexpensive? The author doesn't say why such a system would be inexpensive and competitive, compared to conventional freeways, or why it hasn't been already developed.

Just like the automatic driving system, which is an assembly of existing components, some of the other scenarios lack imagination. In the automated factory of the future we find surprisingly oldfashioned machine tools being attended by man-like robots equipped with two why not four or ten?

The space colonies are "very Earthlike", full of flowers, trees and birds. O'Neill's confirms what the late Marshall McLuhan noted when he wrote in The Medium is the Massage : "We impose the form of the old on the content of the new.

The malady lingers on.

Computer Graphics: Principles and Practice in C, 2nd Edition

We march backwards into the future. A reader with scientific and technical background must look elsewhere for plausible scenarios. Fundamentals of Interactive Computer Graphics.

James D. Major differences from the first edition include the following: The vector-graphics orientation is replaced by a raster orientation. We explain how to do applications programming in each of these packages and who how to implement the basic clipping, scan conversion, viewing, and display list traversal algorithms that underlie these systems.

Interactive 3D Computer Graphics in Medical Imaging

User-interface issues are discussed at considerable length, both for 2D desktop metaphors and for 3D interaction devices. Coverage of modeling is expanded to include NURB nonuniform rational B-spline curves and surfaces, a chapter on solid modeling, and a chapter on advanced modeling techniques, such as physically based modeling, procedural models, factals, L-grammar systems, and particle systems.

Increased coverage of rendering includes a detailed treatment of antialiasing and greatly expanded chapters on visible-surface determination, illumination, and shading, including physically based illumination models, ray tracing, and radiosity. Material is added on advanced raster graphics architectures and algorithms, including clipping and scan-conversion of complex primitives and simple image-processing operations, such as compositing.

A brief introduction to animation is added. This text can be used by those without prior background in graphics and only some background in Pascal programming, basic data structures and algorithms, computer architecture, and simple linear algebra. An appendix reviews the necessary mathematical foundations. The book covers enough material for a full-year course, but is partitioned into groups to make selective coverage possible.

The reader, therefore, can progress through a carefully designed sequence of units, starting with simple, generally applicable fundamentals and ending with more complex and specialized subjects.

Basic Group. Chapter 1 provides a historical perspective and some fundamental issues in hardware, software, and applications. Chapters 2 and 3 describe, respectively, the use and the implementation of SRGP, a simple 2D integer graphics package. Chapter 4 introduces graphics hardware, including some hints about how to use hardware in implementing the operations described in the preceding chapters.

The next two chapters, 5 and 6, introduce the ideas of transformations in the plane and 3-space, representations by matrices, the use of homogeneous coordinates unify linear and affine transformations, and the description of 3D views, including the transformations from arbitrary view volumes to canonical view volumes.

Chapter 7 also discusses the advantages and disadvantages of the hierarchy available in PHIGS and the structure of applications that use this graphics package.

User Interface Group. Chapters describe the current technology of interaction devices and then address the higher-level issues in user-interface design.

Various popular user-interface paradigms are described and critiqued.

In the final chapter user-interface software, such as window mangers, interaction technique-libraries, and user-interface management systems, is addressed. Model Definition Group.

The first two modeling chapters, 11 and 12, describe the current technologies used in geometric modeling: Chapter 13 introduces the human color-vision system, various color-description systems, and conversion from one to another.

This chapter also briefly addresses rules for the effective use of color. Image Syntheses Group. Chapter 14, the first in a four-chapter sequence, describes the quest for realism from the earliest vector drawings to state-of-the-art shaded graphics. The artifacts caused by aliasing are of crucial concern in raster graphics, and this chapter discusses their causes and cures in considerable detail by introducing the Fourier transform and convolution.

Chapter 15 describes a variety of strategies for visible-surface determination in enough detail to allow the reader to implement some of the most important ones. Illumination and shading algorithms are covered in detail in Chapter The early part of part of this chapter discusses algorithms most commonly found in current hardware, while the remainder treats texture, shadows, transparency, reflections, physically based illumination models, rat tracing, and radiosity methods.

The last chapter in this group, Chapter 17, describes both image manipulations, such as scaling, shearing, and rotating pixmaps, and image storage techniques, including various image-compression schemes. Advanced Techniques Group. The last four chapters give an overview of the current state of the art a moving target, of course.

Chapter 18 describes advanced graphics hardware used in high-end commercial and research machines; this chapter was contributed by Steven Molnar and Henry Fuchs, authorities on high-performance graphics architectures.

Chapter 19 describes the complex raster algorithms used for such tasks as scan-converting arbitary conics, generating antialiased text, and implementing page-description languages, such as PostScript.

The final two chapters survey some of the most important techniques in the fields of high-level modeling and computer animation. The first two groups cover only elementary material and thus can be used for a basic course at the undergraduate level. A follow-on course can then use the more advanced chapters.

Alternatively, instructors can assemble customized courses by picking chapters out of the various groups.

For example, a course designed to introduce students to primarily 2D graphics would include Chapters 1 and 2, simple scan conversion and clipping from Chapter 3, a technology overview with emphasis on raster architectures and interaction devices from Chapter 4, homogeneous mathematics from Chapter 5, and 3D viewing only from a "how to use it" point of view from Sections 6.

The User Interface Group, Chapters , would be followed by selected introductory sections and simple algorithms from the Image Syntheses Group, Chapters 14, 15, and A one-course general overview of graphics would include Chapters 1 and 2, basic algorithms from Chapter 3, raster architectures and interaction devices from Chapter 4, Chapter 5, and most of Chapters 6 and 7 on viewing and SPHIGs. The second half of the course would include sections on modeling from Chapters 11 and 13, on image syntheses from Chapters 14, 15, and 16, and on advanced modeling from Chapter 20 to give breadth of coverage in these slightly more advanced areas.

A course emphasizing 3D modeling and rendering would start with Chapter 3 sections on scan converting, clipping of lines and polygons, and introducing antialiasing. The course would then progress to Chapters 5 and 6 on the basic mathematics of transformations and viewing. Chapter 13 on color, and then cover the key Chapters 14, 15 and 16 in the Image Syntheses Group. Coverage would be rounded off by selections in surface and solid modeling.

Chapter 20 on advanced modeling, and Chapter 21 on animation from the Advanced Techniques Group. Acknowledgments This book could not have been produced without the dedicated work and the indulgence of many friends and colleagues.

We acknowledge here our debt to those who have contributed significantly to one or more chapters; many others have helped by commenting on individual chapters, and we are grateful to them as well. We regret any inadvertent omissions. Additional valuable editing on multiple versions of multiple chapters was provided by Debbie van Dam, Melissa Gold, and Clare Campbell. We are especially grateful to our production supervisor Bette Aaronson, our art director, Joe Vetere, and our editor, Keith Wollman, not only for their great help in producing the book, but also for their patience and good humor under admittedly adverse circumstances--if we ever made a promised deadline during these frantic five years, we can't remember it!

Computer graphics has become too complex for even a team of four main authors and three guest authors to be expert in all areas. We relied on colleagues and students to amplify our knowledge, catch our mistakes and provide constructive criticism of form and content.

We take full responsibility for any remaining sins of omission and commission. Several colleagues, including Jack Bresenham, Brian Barsky, Jerry Van Aken, Dilip Da Silva who suggested the uniform midpoint treatment of Chapter 3 and Don Hatfield, not only read chapters closely but also provided detailed suggestions on algorithms.
