I dont think this is the coresponding examples ...

[benjaminfauchald]

these examples seem to correspond to http://www.webgltutorials.org/ not to the Gems / Chapters in the book. Can you please provide the examples that go with the book?

Its not easy to type in all this text especially when you do not know if the code actually showing in the pages is the complete addition to the file.

There may be some overlap between the examples. Can you please point out a specific sample you are working with? I might be able to point you in the right direction or give you the original examples I used when writing the book. Thanks, and sorry about the inconvenience.
