The book has great ideas inside but some of them are presented like marketing material. They give lots of information on the innovation but they do not include enough detail to reproduce the effects.
The actual code included is a very small fraction of the complete code. In some cases it makes sense only to people who are deeply involved into the specific problem.
The wording/structure resembles more the Siggraph ACM Proceedings book, where they explain techniques but not with enough detail so that you can reproduce them. It is not definitely the cookbook I imagined to be when I ordered it.
