Reading about all of the math involved in making models was exhausting. It is good to have an understanding of how the computer understands the models, but I am very glad that the computer deals with the majority of the math and I just get to concentrate on making things look pretty. The explanation about the difference between local and global transformations was very helpful. Reading the exact description of all of the different navigation terms was also very helpful, it is explaining the things we have been doing all along. Having the experience in Maya made all of these terms understandable, and reading about them after the experience made them make more sense. I think that if I had read these chapters before getting started in maya, this would have all been total gibberish to me.
Chapter 4 explored some things that I didn't know about before and better explained parts of Maya that I am very familiar with. I definitely want to learn more about sweeping and try it out. I would also like to experiment with text and other things with making 2-dimensional objects into 3d. I would also love to learn more about Visemes, which was only briefly mentioned towards the end of the chapter, and briefly mentioned by Arturo.
