Physically Based Rendering: From Theory to Implementation

Free sample

Rendering is a crucial component of computer graphics— the conversion of a description of a 3D scene into an image for display. Algorithms for animation, geometric modeling, and texturing all must feed their results through some sort of rendering process for the results to be visible in an image. Focusing on realistic images, physically based rendering incorporates ideas from a range of disciplines, including physics, biology, psychology, cognitive science, and mathematics. This book presents the algorithms of modern photorealistic rendering and follows step by step the creation of a complete rendering system. As each new rendering concept is introduced it is also shown implemented in code—there is no better way to understand the subtle and complex process of rendering. The code itself is highly readable, written in the literate programming style that mixes text describing the system with the code that implements it. The result is a stunning achievement in graphics education for students, professionals, and researchers.

*CD-ROM with the source code for a complete rendering system for Windows, OS X, & Linux—with many examples of images created by the system throughout the 4 color text
*The code and text are tightly woven together through the technique of literate programming with a unique indexing feature that lists all locations of functions, variables, and methods on the page they are first described
*The most complete guide to understanding, designing, and building a rendering system

The present AutoCAD reference guide is, basically, an extension of our teaching, training and working experience in the CAD (Computer Aided Design) field and covers only ~200 commands of AutoCAD. In a productivity war, not only fewer weapons (tools and commands) force us to imbibe the defeat, but more than enough weapons are also suicidal (because we have less time for selection of weapon, too). So a compromising balance has been tried to achieve the optimum.

The available average good books on AutoCAD are horribly containing 2-3 thousands of pages for main text, with dozens of pages, only for their contents. All these mess is full of unnecessary details of even very simpler commands, which user can easily learn intuitively. Even after the bulk of pages they skip some really useful commands, which could otherwise boost the productivity of end user. 

While this reference guide is intended to provide a compact guide of AutoCAD to a wide range of working CAD professionals and students, ranging from engineering streams (architectural, civil, mechanical, electrical, etc.) to non-technical streams. We are relying heavily on the AutoCAD’s user friendly interface while writing the reference guide, as after entering the command alias in AutoCAD, it,  itself, tells ‘n asks for minimum ‘n necessary details through command line. So, practically, there is no need of written procedural details.

As this reference guide book is complimentary with the ‘AutoCAD-Advanced’ and ‘AutoCAD-Professional’ courses of ‘4Dimensions’, most commands given in this guide need at least one time lab training on real projects by an experienced tutor/professional. Each command, once mastered, doesn’t need the whole procedure to be remembered exactly (as different versions may have different procedures).

This video book will quickly teach you what every photographer needs to know about Photoshop CC, including:

 * Removing blemishes and distractions

 * Creating amazing, natural-looking portraits

 * Changing the color of clothing and hair

 * Changing the shape of bodies and objects

 * Using layers, adjustment layers, and masks

 * Replacing skies and backgrounds

 * Straightening lines and buildings

 * Compositing multiple images together

 * Changing facial expressions and poses

 * Creating complex selections and masks

 * Creating panoramas

 * Creating actions to automate tasks

 * Choosing the best image formats

 * Customizing and configuring Photoshop CC

Tony & Chelsea go beyond teaching you how to use Photoshop; they teach you why and when to use each feature to create stunning, natural images. When Photoshop isn’t the best tool, they suggest other alternatives.

Combining the benefits of video training and book learning, this video book gives you over 10 hours of video and dozens of images to practice with. If you learn better with video, watch the video training and refer to the book for quick reference. For best results, walk through each procedure in the book using the provided sample images. Then, watch the videos to learn more advanced and artistic techniques. If you still have questions, or want peer review, join our Photoshop group on Facebook and get feedback from other Photoshop users.

Tony and Chelsea cover every aspect of Photoshop in-depth, but structure their teaching so that both beginner and advanced photographers can learn as efficiently as possible. If you just want a quick start, you can watch the first video or read the first chapter and you'll know the basics of photo editing in less than an hour. If you want to know more about a specific feature, switch to that video or jump to that chapter in the ebook. If you want to know everything about Photoshop, watch the videos and read the book from start to finish. 

Physically Based Rendering, Second Edition, describes both the mathematical theory behind a modern photorealistic rendering system as well as its practical implementation.

A method known as literate programming combines human-readable documentation and source code into a single reference that is specifically designed to aid comprehension. The result is a stunning achievement in graphics education. Through the ideas and software in this book, you will learn to design and employ a full-featured rendering system for creating stunning imagery.

This new edition greatly refines its best-selling predecessor by streamlining all obsolete code as well as adding sections on parallel rendering and system design; animating transformations; multispectral rendering; realistic lens systems; blue noise and adaptive sampling patterns and reconstruction; measured BRDFs; and instant global illumination, as well as subsurface and multiple-scattering integrators.

These updates reflect the current state-of-the-art technology, and along with the lucid pairing of text and code, ensure the book's leading position as a reference text for those working with images, whether it is for film, video, photography, digital design, visualization, or gaming.
