## What it is
The official sample code repository accompanying the OpenGL ES 3.0 Programming Guide book by Addison-Wesley. It provides C/C++ (and Java) example programs demonstrating OpenGL ES 3.0 graphics programming across Windows, Linux, Android, and iOS.

## Use cases
- learn OpenGL ES 3.0 graphics programming
- find example code for OpenGL ES shaders and rendering
- port OpenGL ES samples to Android NDK or iOS
- reference working code while reading the OpenGL ES 3.0 book
- experiment with 3D graphics on mobile GPUs
- set up a cross-platform OpenGL ES build environment

## When to choose
- you are learning OpenGL ES 3.0 from the companion book
- you want canonical, per-chapter sample code for ES 3.0 APIs
- you need multi-platform (Windows/Linux/Android/iOS) graphics examples

## When to avoid
- you need a production graphics engine or framework
- you want Vulkan, Metal, or desktop OpenGL examples
- you need actively developed features or community support

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: graphics, game-engine, developer-tools
- domain: graphics, tutorials, cross-platform
- platform: windows, cross-platform, cpp
- tags: opengl-es, sample-code, graphics-programming, book-companion, shaders, 3d-graphics, game-development, linux, android, ios
