The OpenGL Shading Language (GLSL) is now a fundamental and critical part of programming with OpenGL. It provides us with unprecedented flexibility and power by making the formerly fixed-function graphics pipeline programmable. With GLSL, we can leverage the Graphics Processing Unit (GPU) to implement advanced and sophisticated rendering techniques and even do arbitrary computation. With GLSL 4.x, programmers can do more with the GPU than ever before thanks to shader stages such as tessellation shaders and compute shaders.
In this book, we cover the full spectrum of GLSL programming. Starting with the basics of shading with the vertex and fragment shaders, we take you from simple to advanced techniques. From textures, shadows, and ...
