The primary focus of this book is the OpenGL Shading Language (GLSL). Therefore, we don't spend any time discussing the basics of programming with OpenGL. In this book I assume that the reader has some experience with programming in OpenGL, and understands 3D rendering concepts such as model coordinates, view coordinates, clip coordinates, perspective transforms, and the other associated transformations. There's no assumption of any experience with shader programming, however, so if you're new to GLSL, this is a great place to start.
If you're an OpenGL programmer looking to learn about GLSL programming, then this book is for you. Even if you have some shader programming experience, you will very likely find the recipes ...
