Divided into specific areas in computer graphics, like colour theory, animation, compositing and others, CG 101 begins each section with a brief introduction where general but important concepts are covered. For example, prior to the list of terms under Colour Theory, the book provides a discussion on why computer graphics uses the RGB (red, green, blue) colour system instead of the CMYK (cyan, magenta, yellow, black) system used in printing. The section on Painting and Graphic Design lists software tools used in 2D computer graphics, particularly the early ground-breaking ones such as 1975's SuperPaint or 1985's Harry, a predecessor to Quantel's Paintbox, which paved the way for today's state-of-the-art methods.
In the margins are quotes from industry leaders, trivia and "factoids" (for example, the 24-bit paint system Paint was used to create landscape and cloud details in 1982's Star Trek II: The Wrath of Khan and other entertaining sidebars (for example, how Pixar got its name).
CG 101 also includes telephone numbers and URLs for most of the companies mentioned in the book and even tips on good software deals. Small illustrations, many in colour, visually clarify technical or scientific information and illustrate terms.
An excellent example of how much varied and useful information is contained in each section can be found in the chapter on Rendering, which focuses on the history of the computer graphics solutions, not the mathematics behind the process. Along with terms like bump mapping (surface normal perturbation that does not effect the underlying geometry) and mach- banding(an optical illusion occurring when two edges of different colour values are adjacent), the author provides "a list of what you do not see in reality" and thus what to avoid in realistic-looking computer graphics. For example, he writes, "There are no straight lines in nature" and "The real world is dirty" and explains what he means by each.
Here, as throughout CG 101, the text refers to many well-known projects where computer graphics played a big role in films like StarWars and Toy Story. These references serve two purposes: they give perspective to the complexities involved in modern filmmaking as well as give a detailed view of what a job in computer graphics might entail.
The author comes with impressive credentials in the field, including extensive work at George Lucas's Industrial Light and Magic and offers ample sound advice to those entering computer graphics. For example, in the preface to the modelling terms he states, "The most important thing I can say from experience is to be mindful of your data." He says in reference to animation, "It takes years of experience, loads of raw talent and knowledge of character animation", after which he explains the major issues to keep in mind when bringing an animated character to life.
Adding to this career advice are the final chapters on the history of computer graphics and on historically significant companies, including appendices with job descriptions (for example, character animator or modeller). You'll also find frequently asked questions, thus making this the perfect book for anyone contemplating a career in computer graphics or maybe even those just daydreaming about one. --Angelynn Grant,amazon.com
Topics covered: terms in computer graphics, including colour and light, painting and graphic design related to computer graphics (image processing and photo editing), modelling, animation (traditional and computer), rendering, compositing, input (devices like drawing tablets or the DataGlove) and output (from the old pen plotters to digital projections); historically significant companies in computer graphics; the programming and mathematics behind computer graphics; a history of computer graphics from the 1940s to the present; frequently asked questions; a list of computer graphics job descriptions; and discussions of previsualization ("the process of using 3D animation tools to plan complicated visual effects sequences prior to the production of any elements of the shot") and the era of analogue computer animation.
CG101 is the first comprehensive resource guide written in plain language for all levels of computer graphics users. It is also the first and only detailed behind-the-scenes history about the people and companies that have formed today's industry. Hundreds of contributors and in-depth interviews give a never-before-seen look into the earliest years of CG right up to present day. In addition to the historical perspective, CG 101 includes detailed tips and tricks, demo reel guidelines and CG job descriptions to help those looking to get into the business. The hundreds of software tool descriptions all have extensive contact information, including Web addresses and phone numbers for easy reference.
