Example code from the OpenGL 4 Shading Language Cookbook, 3rd Edition

The example code from the OpenGL 4 Shading Language Cookbook, 3rd Edition, by David Wolff and published by Packt Publishing.


To compile these examples, you'll need the following:

  • The GLM Mathematics Library version 0.9.6 or later. Note that versions prior to 0.9.6 may not work properly because of a switch from degrees to radians. GLM 0.9.5 will work, but you'll need to add
    prior to including the glm header files.
  • GLFW version 3.0 or later.

Compiling the examples

The example code builds with CMake. Note that the examples for Chapter 10 will not function on MacOS due to lack of support for compute shaders on that platform.

  1. Install GLFW by following the instructions on their web site.
  2. Install the latest version of GLM. Note that for CMake to find GLM correctly, you need to run the install "build" (e.g.
    make install
    ) or install GLM from your favorite package manager. Otherwise, the CMake config files will not be created/available.
  3. Download this example code from github, or clone using git.
  4. Run cmake. If cmake has difficulties finding the GLFW or GLM installations, set the variable
    to help cmake find them.
    It can be tricky to get CMake to find the GLM libraries, unfortunately. See below for tips.
  5. Compile by running

Tips for getting CMake to find GLM

When searching for GLM, CMake looks for the files


If you install GLM using a package manager such as Homebrew on macOS, or a Linux package manager the cmake files should already be included.

Otherwise, if you're using the GLM source distribution, you'll have to run GLM through CMake to get it to generate the

files. It is frustrating, I wish that the GLM maintainers didn't require this.
  1. Download GLM and extract it to some location:
  2. cd $GLM_SRC
  3. mkdir build
  4. cd build
  6. cmake --build . --target install


above with the place where you extracted the GLM zip file, and replace
with the location where you want to install GLM. This should generate the needed cmake files and install all of GLM to

Tips for compiling for Windows with Visual Studio

  • Use the Visual Studio target in CMake:
    -G "Visual Studio..."
    , open the Visual Studio solution. You should see one project per chapter.
  • Each chapter requires a command line argument to choose a recipe. When running in VS, be sure to set the 'Command Argument' under 'Properties' for the appropriate recipe.

OpenGL Function Loading

An OpenGL header file and a function loader for a 4.3 core profile are included with this project. They were generated using GLAD. This loader should also work on MacOS under a 4.1 core profile, but of course not all functions will load.

The code has been tested with OpenGL 4.3 on Windows/Linux and OpenGL 4.1 on MacOS.

OpenGL 4 Shading Language Cookbook - Third Edition

This is the code repository for OpenGL 4 Shading Language Cookbook - Third Edition, published by Packt.

Build high-quality, real-time 3D graphics with OpenGL 4.6, GLSL 4.6 and C++17

What is this book about?

OpenGL 4 Shading Language Cookbook, Third Edition provides easy-to-follow recipes that first walk you through the theory and background behind each technique, and then proceed to showcase and explain the GLSL and OpenGL code needed to implement them.

This book covers the following exciting features: * Compile, debug, and communicate with shader programs * Use compute shaders for physics, animation, and general computing * Learn about features such as shader storage buffer objects and image load/store * Utilize noise in shaders and learn how to use shaders in animations * Use textures for various effects including cube maps for reflection or refraction

Instructions and Navigations

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

GLFWwindow *window = glfwCreateWindow(800, 600, "Title", nullptr, nullptr);

Following is what you need for this book: If you are a graphics programmer looking to learn the GLSL shading language, this book is for you. A basic understanding of 3D graphics and programming experience with C++ are required.

With the following software and hardware list you can run all code files present in the book (Chapter 1-11).
