A Solid Reference Book,
This review is from: OpenGL Shading Language (Paperback)
I was surprised at how large this book was when it arrived: bigger than the main OpenGL reference book in the same series. And the material is a little dilute - 200 pages of top quality content packed into a 600 page book.
I got slightly frustrated that it took several chapters to get into the meat of the book: before the authors got to creating useful shaders. But with hindsight, the basic material is very useful. There are gotcha's in the shading language, and the authors do a good job of making the path as plain as possible.
Even though fewer and fewer projects I work on (I work in the games industry) use OpenGL, the shading language is probably the most important addition to the OpenGL API for years. It is a standard, and the book was designed to document that standard. Most of the last section of the book is an in depth reference which is useful to have.
I found some chapters absolutely superb. But a lot of the book's material was wasted on me. The stuff on procedural shading is much better covered in other books. Generating a mandlebrot shader, for example, is hardly useful in a real project, in my opinion.
So I'd recommend the book to anyone who needs to understand GLSL. The bit that's useful is very useful, and I felt it was completely worth the cover price. The rest of the book, as my wife said, is a bit of a waste of trees.
