Not the best book I read.,
Verified Purchase(What's this?)
This review is from: OpenGL Shading Language (3rd Edition) (Paperback)
The authors honestly warn the user that this book is not intended to be read from start to finish in sequential order. Cannot agree more. The material is scattered through the book with little logical order. Very often I find myself putting the book aside and going to Internet after futile attempts to find even some basic information.
For example GLSL defines a number of special embedded variables, but you will not find a list of those variables and especially examples of using them. Instead they are scattered in the text.
A good part of the book is just examples of solving some fancy tasks. GLSL is a very interesting and exciting subject and I expected to find something more useful when ordering this book.
Save your money.
