## What it is
A series of tutorials teaching WebGL from the ground up, covering shaders, GLSL, 2D/3D math, lighting, textures, and rendering techniques. The lessons are written specifically for WebGL rather than being adapted from older OpenGL material, and include runnable examples and helper library docs.

## Use cases
- learn webgl from scratch
- understand glsl shaders
- learn 3d math for graphics programming
- learn how to do image processing in webgl
- understand matrices and transformations in 3d
- learn lighting and shadow techniques in webgl
- find webgl examples and boilerplate code

## When to choose
- you want to learn WebGL fundamentals from first principles rather than outdated OpenGL tutorials
- you need clear step-by-step explanations of 2D/3D math, matrices, and shaders
- you want runnable examples covering textures, lighting, shadows, and rendering techniques

## When to avoid
- you need a production-ready 3D engine or framework rather than educational material
- you want a high-level abstraction like three.js instead of learning the low-level API
- you need comprehensive WebGL2 coverage, which lives in the separate webgl2fundamentals.org site
