LearnOpenGL is a free online tutorial that teaches modern OpenGL from basic to advanced levels, offering step‑by‑step examples and a print edition.

The author notes that many existing resources concentrate on legacy OpenGL and are incomplete, prompting the creation of a comprehensive guide.

The tutorial begins with core graphics concepts and how OpenGL renders pixels, then progresses through lighting, scene traversal, model loading, and post‑processing techniques. A guided game project demonstrates practical application of the material.

The content is available online at no cost, and a printed version can be purchased from major retailers for approximately $60. A PDF version is also offered for free offline reading. The author encourages followers to track updates on Twitter.
