techniques from professional cinematography, design principles from traditional visual arts, practical advice based on professional film production experience, and plainEnglish explanations of the latest science behind the scenes Who Should Read This Book? You should read this book when you have at least a working knowledge of how to use a 3D package, and are interested in taking your 3D rendering further For professional users of 3D rendering software, this book is designed to help with real-world production challenges and contribute to the ongoing growth of your work For students of computer graphics, this book will help you develop more professional rendering skills For dedicated 3D hobbyists, this book can help you improve the artistic quality of your 3D renderings and learn more about professional approaches to graphics production This book is written to be clear, but not condescending Every effort has been made to define terms the first time they are used, and to illustrate every concept and technique with figures and sample renderings This book is designed to complement, rather than to replace, your software's manuals and help files Most of the information you find here is not in your software's manual, even if some of it should be Software Requirements This book covers techniques and concepts that are applicable to work in almost any 3D rendering software 2D Paint and compositing software is also recommended 3D Software No single program is going to support every feature, function, and rendering algorithm described in this book Hopefully you won't mind learning about a few functions that aren't in your particular software yet However, most sections show several alternate approaches or work-arounds so that you can achieve any effect that is described, no matter which program you use Being non-software-specific doesn't mean that this book doesn't discuss particular software, though If there's a noteworthy feature in Renderman, Mental Ray, 3D Studio Max, Maya, Softimage, Lightwave, or any other program, it will be mentioned when it comes up This book is dedicated to the idea that, with an awareness of the art and computer graphics principles that go into a rendering, and a little bit of creative problem solving, you can accomplish great work in almost any rendering package 2D Software Any good 3D system should be complemented with 2D software to create and manipulate texture maps, and to composite together layers and render passes Ideally you should have a paint program such as Adobe Photoshop (used in many texturecreation examples in this book), Paint Shop Pro, or Fractal Painter Free alternatives such as The Gimp or Paint.NET will also work just fine A dedicated compositing program, such as Shake, Digital Fusion, or After Effects, is useful when compositing together render passes, although you could also do basic compositing of still images in your paint program About This Edition This is the second edition of the popular book [Digital] Lighting & Rendering The first edition became the standard text on the art of 3D lighting and rendering, and introduced many artists to the field Since it was published in 2000, it has met with great critical and commercial success I am sincerely grateful to each teacher who has chosen to assign my book to students, everyone on the Internet who has posted a recommendation, and every artist who has shown my book to a friend or colleague This new edition has advanced along with changes in technology, in software, and in the industry To keep up with an evolving field, every chapter has grown with new techniques and concepts Issues such as occlusion and global illumination, which had been relegated to single sections in the first edition, are now woven throughout the book, in discussions of different issues from architectural rendering to render passes A new chapter has also been added on understanding studio production pipelineshow professionals work together in different positions to create feature-film visual effects and computer animated features In computer graphics, we say our work is never really completed, only abandoned Shots always could be better, always could be tweaked and revised a little more by perfectionist artists Crashing into a deadline is what finally forces us to let go of the projects we love The same is true in releasing a book I'm glad that what I abandoned in 2000 has made so many people happy The first edition represented the best of what I had to say that year Since then I have continued .. .Digital Lighting & Rendering, Second Edition By Jeremy Birn Publisher: New Riders Pub Date: April 27, 2006 Print ISBN- 10: 0-321-31631-2 Print ISBN- 13: 978-0-321-31631-8...
