## What it is
The source code and content of Open.GL, a tutorial website teaching modern OpenGL (3.2+) graphics programming in C++, also available as EPUB/PDF e-books. The repository hosts the PHP site code, article content, and CC0-licensed code examples.

## Use cases
- learn modern OpenGL from scratch
- find an OpenGL tutorial without deprecated functions
- download an OpenGL guide as an ebook
- suggest improvements to the Open.GL tutorial site
- get example code for shaders and rendering in C++

## When to choose
- you want to learn modern, core-profile OpenGL with interactive examples
- you prefer a concise guide available offline as EPUB or PDF
- you want public-domain (CC0) sample code to reuse freely

## When to avoid
- you need Vulkan, DirectX, or Metal tutorials
- you want a maintained course with recent OpenGL or graphics API coverage
- you need a library or tool rather than learning material

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, graphics
- domain: graphics, tutorials, education
- platform: cross-platform, cpp
- tags: opengl, tutorial-site, ebook, graphics-programming, cc0-code-examples, game-development
