## What it is
A series of open-source tutorials teaching WebGL2 from first principles, with runnable HTML examples covering shaders, 2D/3D math, textures, lighting, and rendering techniques. The repository contains the lesson content and source for the webgl2fundamentals.org site, including translations and helper utility docs.

## Use cases
- learn webgl2 from scratch
- understand how webgl shaders work
- learn 3d math for web graphics
- do image processing with webgl
- render textures and shadows in the browser
- migrate from webgl1 to webgl2
- find webgl tutorials that aren't based on old opengl

## When to choose
- you want to learn WebGL2 fundamentals from the ground up
- you prefer modern WebGL-native explanations over rehashed OpenGL tutorials
- you need runnable, step-by-step examples with translations

## When to avoid
- you need a production graphics engine or framework rather than lessons
- you want WebGL 1.0 content specifically
- you need a structured course with instructor support

## Facets
- artifact type: learning-resource
- maturity: active
- function: graphics, image-processing, documentation
- domain: graphics, web-development, tutorials, education
- platform: browser, cross-platform
- tags: webgl2, webgl, tutorials, shaders, glsl, 3d-graphics, 2d-graphics, gpu-programming, lessons, web-server
