Computer Graphics: Principles and Practice, Third Edition, remains the most authoritative introduction to the field. The first edition, the original “Foley and van Dam,” helped to define computer graphics and how it could be taught. The second edition became an even more comprehensive resource for practitioners and students alike. This third edition has been completely rewritten to provide detailed and up-to-date coverage of key concepts, algorithms, technologies, and applications.

The authors explain the principles, as well as the mathematics, underlying computer graphics–knowledge that is essential for successful work both now and in the future. Early chapters show how to create 2D and 3D pictures right away, supporting experimentation. Later chapters, covering a broad range of topics, demonstrate more sophisticated approaches. Sections on current computer graphics practice show how to apply given principles in common situations, such as how to approximate an ideal solution on available hardware, or how to represent a data structure more efficiently. Topics are reinforced by exercises, program­ming problems, and hands-on projects.

This revised edition features

The text and hundreds of figures are presented in full color throughout the book. Programs are written in C++, C#, WPF, or pseudocode–whichever language is most effective for a given example. Source code and figures from the book, testbed programs, and additional content will be available from the authors' website (cgpp.net) or the publisher's website  (informit.com/title/9780321399526). Instructor resources will be available from the publisher. The wealth of information in this book makes it the essential resource for anyone working in or studying any aspect of computer graphics.

This book is an essential guide to some of the best free add-ons to PHP. These add-ons, or tools, provide invaluable functionality for improving your PHP web applications, including accessing databases, generating robust Web forms, using page templating systems, creating and parsing XML documents, authenticating users, and much more.

In response to the existing shortage of documentation about the tools, author David Sklar packs this book with details about installing, configuring, and using each tool—along with plenty of examples tailored to PHP 4 and 5.

Sklar also lays out the details of Auth and HTML_QuickFormtwo hard working PEAR modules, so you don''t have to code your own authentication system or Web form construction set! Also included are chapters on debugging programs, and increasing Web server speed. In short, you will learn to eliminate inefficiencies in PHP, and enhance performance without any code modification.

If you want to get started with PHP, this book is essential. Author David Sklar (PHP Cookbook) guides you through aspects of the language you need to build dynamic server-side websites. By exploring features of PHP 5.x and the exciting enhancements in the latest release, PHP 7, you’ll learn how to work with web servers, browsers, databases, and web services. End-of-chapter exercises help you make the lessons stick.

Whether you’re a hobbyist looking to build dynamic websites, a frontend developer ready to add server-side programs, or an experienced programmer who wants to get up to speed with this language, this gentle introduction also covers aspects of modern PHP, such as internationalization, using PHP from the command line, and package management.

How far would you go to save someone you barely knew, if it put your own life in danger?

When Andrew, an American medical student, decides to climb Mt. Kilimanjaro with a group of international travelers, he''s looking forward to the adventure. But when the climb takes an unexpected turn, it forces the climbers to confront their deepest fears-and each other.

In the middle of the night, just a few hours from the summit, Barry, one of Andrew''s fellow climbers, becomes deathly ill. As the only one with medical expertise, Andrew feels responsible for Barry''s fate. Saving Barry means risking his own life, but failing to act will compromise his values as a healer and human being. It doesn''t help that he''s falling for Barry''s climbing companion and girlfriend, a beautiful Peace Corps volunteer whose free spirit makes methodical, meticulous Andrew feel alive.

All of the climbers are haunted by their choices during that terrifying night and its aftermath...but Andrew, most of all. Torn between descending Africa''s highest peak in the dark to save a near-stranger, or fulfilling his dream of reaching the summit, Andrew must choose. And in the wake of his choice, his life will change forever.
