Meanwhile, any explanation of the OpenGL API being called inside that function is missing completely - and a listing for the function is also missing.Īll in all, this is a pretty useless and confusing book. There's also the use of home-grown software to skip over certain important details - the book uses several pages to describe how to use a function that isn't even in OpenGL, but part of the authors' personal library.

I understand a book must have a limited length, but a book that positions itself as 'the official guide to learning' should surely prioritize the basics of the API over much more esoteric subjects like the procedural texturing chapter? A vital table, explaining what the arguments to glReadBuffer() actually do, and that was present in the predecessor book, is now missing. This book goes into great detail about pointless and redundant functions, like explaining how to allocate, de-allocate, bind, and query for the existence of every type of OpenGL resource (which typically gets a full page per resource, but is always the same except for the function name) - yet it fails to explain what it actually is you are allocating, or what you might use it for, or what a good strategy for its use is.Īs an example: what is a VAO? Sure, having read the book, I know how to allocate one now - now tell me: why would I? What does it do, and how do I best use it?įunction arguments are also barely explained. It represents an enormous step back from the previous version 2 book, which I also have. The book claims to be 'the official guide to learning OpenGL', but it does an absolutely lousy job at helping you understand this complex API.
