## What it is
The official code repository for the LearnOpenGL book and website, containing C++ sample code for every chapter covering modern core-profile OpenGL. It spans basics like windows, shaders, and textures through advanced topics such as PBR, shadow mapping, deferred shading, and a 2D Breakout game.

## Use cases
- learn modern OpenGL from scratch with runnable examples
- understand GLSL shaders and the graphics pipeline
- implement lighting, shadows, and PBR in OpenGL
- load 3D models with Assimp in C++
- build a simple 2D game with sprites and collisions
- reference sample code while writing my own renderer

## When to choose
- you want a well-regarded, structured tutorial with complete working code
- you are learning core-profile OpenGL on Windows, Linux, or macOS
- you need reference implementations of advanced rendering techniques

## When to avoid
- you need a production graphics engine or framework rather than educational samples
- you target Vulkan, DirectX, or Metal instead of OpenGL
- you want a permissive license for copying code into products (license is non-standard)

## Facets
- artifact type: learning-resource
- maturity: stable
- function: graphics, game-engine, developer-tools
- domain: graphics, tutorials, education
- platform: cross-platform, windows, cpp
- tags: opengl, glsl, shaders, 3d-graphics, cmake, glfw, pbr, sample-code, game-development, linux, macos
