Irradiance caching is a ray tracing-based technique for computing global illumination on diffuse surfaces. Specifically, it addresses the computation of indirect illumination bouncing off one diffuse object onto another. The sole purpose of irradiance caching is to make this computation reasonably fast. The main idea is to perform the indirect illumination sampling only at a selected set of locations in the scene, store the results in a cache, and reuse the cached value at other points through fast interpolation. This book is for anyone interested in making a production-ready implementation of irradiance caching that reliably renders artifact-free images. Since its invention 20 years ago, the irradiance caching algorithm has been successfully used to accelerate global illumination computation in the Radiance lighting simulation system. Its widespread use had to wait until computers became fast enough to consider global illumination in film production rendering. Since then, its use is ubiquitous. Virtually all commercial and open-source rendering software base the global illumination computation upon irradiance caching. Although elegant and powerful, the algorithm in its basic form often fails to produce artifact-free mages. Unfortunately, practical information on implementing the algorithm is scarce. The main objective of this book is to show the irradiance caching algorithm along with all the details and tricks upon which the success of its practical implementation is dependent. In addition, we discuss some extensions of the basic algorithm, such as a GPU implementation for interactive global illumination computation and temporal caching that exploits temporal coherence to suppress flickering in animations. Our goal is to show the material without being overly theoretical. However, the reader should have some basic understanding of rendering concepts, ray tracing in particular. Familiarity with global illumination is useful but not necessary to read this book.

This book is suitable for undergraduate students in computer science and engineering, for students in other disciplines who have good programming skills, and for professionals. Computer animation and graphics are now prevalent in everyday life from the computer screen, to the movie screen, to the smart phone screen. The growing excitement about WebGL applications and their ability to integrate HTML5, inspired the authors to exclusively use WebGL in the Seventh Edition of Interactive Computer Graphics with WebGL. Thisis the only introduction to computer graphics text for undergraduates that fully integrates WebGL and emphasizes application-based programming. The top-down, programming-oriented approach allows for coverage of engaging 3D material early in the course so students immediately begin to create their own 3D graphics. Teaching and Learning Experience This program will provide a better teaching and learning experience-for you and your students. It will help: *Engage Students Immediately with 3D Material: A top-down, programming-oriented approach allows for coverage of engaging 3D material early in the course so students immediately begin to create their own graphics.*Introduce Computer Graphics Programming with WebGL and JavaScript: WebGL is not only fully shader-based-each application must provide at least a vertex shader and a fragment shader-but also a version that works within the latest web browsers.
The comic book universe is adventurous, mystifying, and filled with heroes, villains, and cosplaying Comic-Con attendees. This book by one of Wired magazine's art directors traverses the graphic world through a collection of pie charts, bar graphs, timelines, scatter plots, and more. Super Graphic offers readers a unique look at the intricate and sometimes contradictory storylines that weave their way through comic books, and shares advice for navigating the pages of some of the most popular, longest-running, and best-loved comics and graphic novels out there. From a colorful breakdown of the DC Comics reader demographic to a witty Venn diagram of superhero comic tropes and a Chris Ware sadness scale, this book charts the most arbitrary and monumental characters, moments, and equipment of the wide world of comics. Plus, this is the fixed format version, which includes high-resolution images.
The book discusses practical issues and provides a complete presentation of the most recent and innovative advances in the radiosity method: an exciting new technique for producing synthetic images. Unique illustrations and 45 color plates make this visually appealing to computer graphics buyers.

Even the most creative minds need stimulation. Inspiration can come from examples of exceptional work, exercises designed to motivate, or time to reflect. The more inventive pieces the mind takes in, the more resources it has to draw from. Street Smart Advertising: How to Win the Battle of the Buzz contains countless examples designed to jump-start the right side of the brain. Margo Berman's book is packed with memorable uses of new media, exciting on-strategy marketing, creative online work, and insightful quotes by giants in the advertising industry. She offers innovative techniques to generate 'sticky' slogans and headlines, easy-to-apply copywriting tips, and practical revision strategies. Berman has updated the book to reflect how online media has changed its approach from 'pushing' information to the audience to 'pulling' - i.e., engaging the audience in a brand. By using social networking groups like Facebook and Twitter, the author points out, even small companies can have a giant digital footprint by leveraging their online presence, offering relevant insights, and stimulating consumer-created content. In tough economic times, Berman says, savvy advertisers don't need huge budgets to engage the audience and create forums for them to share ideas. The biggest change in marketing is reaching people through new touch points: through audience intersection, viral marketing, and online dialogues. As Street Smart Advertising makes clear, those who become victorious in this new marketing arena will win the battle of the buzz.
