The OpenGL Programming Guide

The OpenGL^® Programming Guide
9^th Edition

John Kessenich, Graham Sellers, and Dave Shreiner

Welcome to the website for the OpenGL Programming Guide (the "Red Book"). The latest release — the ninth edition — brings the most comprehensive discussion of the OpenGL API completely up to date. This edition throughly discusses the features of OpenGL version 4.5, OpenGL's latest version, including:

Direct State Access (DSA) which modifies the way that OpenGL objects (e.g., textures, FBOs, etc.) modify their attributes. This approach mitigates the sometimes confusing "bind-to-edit", making it much more straight-forward to understand which objects are being updated.
SPIR-V, The Khronos Group's compiled-shader representation, which allows authoring shaders in just about any programming language – provided there's a SPIR-V backend to the compiler chain. SPIR-V is also one of the major components of Khronos' new Vulkan API.
Expanded discussions of GPU computing (compute shaders) and rendering algorithms, with a focus of doing more work on the GPU.

As always, the Red Book guides the reader from the essientials of using OpenGL including introducing vertex and fragment shaders, through advanced programming techniques using geometry, tesselation, and compute shaders, and all the other features available in OpenGL.

The source code for the 9^th edition is now hosted on Github, or you can download a ZIP archive of the Github repository here.

Thanks, and happy hacking!
