✦ Synopsis

Learning Processing: A Beginner's Guide to Programming Images, Animation, and Interaction КНИГИ ; ПРОГРАММИНГ Название: Learning Processing: A Beginner's Guide to Programming Images, Animation, and Interaction Автор: Daniel ShiffmanИздательство: Morgan Kaufmann Год: 2008 Страниц: 472 Формат: pdf Размер: 5.72 Мб ISBN: 978-0-12-373602-4 Качество: super fine (OCR)This book teaches you the basic building blocks of programming needed to create cutting-edge graphics applications including interactive art, live video processing, and data visualization. A unique lab-style manual, the book gives graphic and web designers, artists, and illustrators of all stripes a jumpstart on working with the Processing programming environment by providing instruction on the basic principles of the language, followed by careful explanations of select advanced techniques. Within these pages, ITP (Tisch School of the Arts, New York University) professor Daniel Shiffman demonstrates the fundamentals of programming that will expand your understanding of what is possible in the world of computer graphics. By travelling beyond the confines of proprietary software, you will be empowered to create your own custom design tools. * A friendly start-up guide to Processing, the visual artist s free, open-source alternative to expensive software and daunting programming languages. * No previous experience required this book is for the true programming beginner! * Step-by-step examples, thorough explanations, hands-on exercises, and simple code samples support your learning curve. Source code and supplemental tutorials are also available through an online companion site. 85
