## What it is
A set of C++ source code samples accompanying the opengl-tutorial.org website, teaching OpenGL 3.3+ and modern 3D graphics programming. It covers basics like drawing triangles up to texturing, matrices, models, and more advanced rendering techniques.

## Use cases
- learn modern OpenGL from scratch
- understand shaders and GLSL basics
- get example code for rendering 3D models
- learn transformation matrices in 3D graphics
- set up a C++ OpenGL project with CMake
- reference code for textures and VAOs

## When to choose
- you are a beginner learning OpenGL 3.3+ with C++
- you want runnable sample code alongside written tutorials
- you need a simple, minimal starting point for graphics programming

## When to avoid
- you need a production-ready graphics engine or framework
- you want actively maintained, up-to-date code with support
- you need Vulkan, DirectX, or WebGL tutorials
- you are on a Mac with integrated GPU (site recommends the 2.1 port instead)

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: graphics, game-engine, developer-tools
- domain: graphics, tutorials, education
- platform: cross-platform, cpp, windows
