If an animator is to really get good at their trade they need to have a bit of knowledge behind them and understand the theories and techniques that are necessary to produce the 3-D, 4D, and 5D graphics special effects that all this modern technology is capable of. Today, in the United States we are outsourcing much of our animation creation to India, so those in the United States that hope to compete must be the best of the best.
Not only must they know the nuts and bolts of the industry, and a good bit about 3-D modeling but they must also understand the texture mapping, lighting, and the drawing and rendering. And even then getting the job is not going to be that easy. Additionally, it should be noted that 3-D animation has its own vocabulary, its own language, and if you can not speak it, you can expect to get in.
If you are really interested in getting a high-paying job in graphic animation, then you need to read up on this subject so that you understand all the ins and outs of the industry. In case you are interested enough to go through the learning curve, I'd like to recommend a least one of the books that you should read. The book is called;
“3D Graphics & Animation; from Starting Up to Standing Out,” by Mark Giambruno; New Riders Publishing; Indianapolis, IN; 1997. ISBN: 1-56205-698-0
This book will help you get a job in film, broadcast television, multimedia or designing games, simulators, or virtual reality environments. It also has chapters on illustration and fine art along with a little bit of information on design and engineering. It's hard to be a good modeler, designer, or mapper until you can also become a good drawer.
Indeed, I think Mark does a good job explaining the entire industry and all that will be involved for the novice all the way up to someone who's been in the business for several years. This book is in fact, a good reference book and if you are a graphic designer, or animator of any type this should be your library; it's in mine.
