## What it is
The official example code repository for the OpenGL Programming Guide (Red Book), 9th Edition, containing a large collection of C/C++ sample programs demonstrating OpenGL 4.5 techniques. It is built with CMake and produces runnable executables for learning modern OpenGL.

## Use cases
- learn OpenGL 4.5 with runnable examples
- study shader programming samples from the Red Book
- reference code for graphics programming in C
- set up a CMake-based OpenGL sample project
- explore rendering techniques like textures, buffers, and transform feedback

## When to choose
- you are reading or studying the OpenGL Red Book 9th Edition
- you want hands-on, compilable examples of modern OpenGL APIs
- you need reference implementations of OpenGL 4.5 features

## When to avoid
- your hardware or drivers only support OpenGL below 4.5
- you need a production-ready graphics engine or library
- you want a tutorial with extensive error handling or documentation beyond the book

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: graphics, simulation, developer-tools
- domain: graphics, tutorials, cross-platform
- platform: windows, cpp, c
- tags: opengl, red-book, example-code, cmake, shaders, computer-graphics, game-development, linux, macos
