## What it is
Demo code accompanying Anton's OpenGL 4 Tutorials e-book, with per-chapter C++ examples covering shaders, vertex buffers, cube maps, and other OpenGL 4 concepts. It includes Makefiles and build scripts for Linux, macOS, and Windows.

## Use cases
- learn OpenGL 4 shader programming from worked examples
- see minimal hello triangle code for modern OpenGL
- understand vertex buffer objects and mesh rendering
- learn cube maps, skyboxes, and environment mapping
- get started with compute shaders and ray tracing in OpenGL
- find reference OpenGL 2.1 hello triangle code

## When to choose
- you are learning OpenGL from Anton's book and want matching runnable demos
- you want small, readable C++ examples of core graphics techniques
- you need cross-platform Makefiles for building OpenGL samples

## When to avoid
- you need a production-ready graphics engine or framework
- you want actively updated examples for the latest OpenGL or Vulkan APIs
- you prefer higher-level rendering libraries over raw OpenGL

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: graphics, developer-tools
- domain: computer-vision, graphics, tutorials
- platform: windows, cpp
- tags: opengl, computer-graphics, shaders, demo-code, ebook, glsl, 3d-graphics, game-development, linux, macos, gpu
