## What it is
A repository of lesson code and tutorials for learning OpenGL ES 2 graphics programming, accompanying the learnopengles.com website. It covers Android and WebGL platforms, teaching shaders, matrices, and rendering fundamentals.

## Use cases
- learn opengl es 2 on android
- learn webgl from scratch
- understand shaders and matrices in graphics programming
- get started with mobile 3d graphics development
- find example code for drawing with opengl es
- learn how to set up an opengl es context

## When to choose
- you want step-by-step tutorials with complete example code for OpenGL ES 2
- you are targeting Android or WebGL for mobile/web graphics
- you are a beginner to shaders and 3D graphics programming

## When to avoid
- you need modern Vulkan or Metal graphics APIs
- you need desktop OpenGL tutorials
- you need an actively maintained library rather than educational sample code

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: graphics, game-engine, developer-tools
- domain: graphics, mobile-development, tutorials, education
- platform: browser, cross-platform
- tags: opengl-es, webgl, shaders, 3d-graphics, tutorials, java, android, game-development
