# WebGL Pro
A practical guide to raw WebGL (WebGL2): contexts, GLSL shaders, buffers, textures, framebuffers, and debugging — for when Three.js/WebGPU are the wrong abstraction and you need direct GPU control.
## Overview
WebGL is the low-level GPU API: you write GLSL shaders, manage buffers, and issue draw calls yourself. It's verbose — a triangle takes ~100 lines — but it gives total control and the widest device support of any web GPU API. Legitimate uses: custom rendering engines, GLSL-heavy effects (shader art, post-processing), tiny-footprint graphics (no library weight), and learning how GPUs actually work.
WebGL2 (not 1) is the baseline: `webgl2` context, GLSL ES 3.00, transform feedback, instancing, integer textures.
## When to use
- Custom 2D/3D rendering where libraries add more weight than value.
- Shader-driven effects: fullscreen fragment shaders, particles, post-processing.
