Animation Methods by David Rodriguez is a very, very good book on learning animation in Maya. It's a book that focuses primarily on 3D Character Animation, a step-by-step guide for learning Maya, and the Maya animation tools. It also has useful sections on how to get into the industry, how to make a great demo reel, and how to get a job in animation. We think this is a very useful companion book to the animation and VFX course at Bucks.
It is also an unusual book in that it makes extensive use of QR codes - meaning you can use your smartphone to scan the codes and then view a 3D animated clip of the lesson. So, not only can you read the lesson, but you can also see and understand it through a video demonstration.
