## What it is
TWGL.js is a tiny JavaScript helper library that reduces the verbosity of the raw WebGL and WebGL2 APIs. It provides concise functions for compiling shader programs, creating buffers, setting uniforms and attributes, creating textures, and managing framebuffers.

## Use cases
- write low-level WebGL code without boilerplate
- compile shaders and set uniforms with minimal code
- create and bind buffers and attributes from arrays
- create textures and framebuffers easily
- build custom WebGL renderers or visualizations
- learn WebGL without a heavy 3D engine

## When to choose
- you want low-level control over WebGL without verbose API calls
- you find three.js too heavy or abstract for your needs
- you're learning WebGL internals
- you need a small dependency for shader-based graphics or effects

## When to avoid
- you want a full-featured 3D engine with scenes, cameras, and loaders — use three.js
- you need high-level abstractions like physics or animation systems
- you're not working with WebGL at all

## Facets
- artifact type: library
- maturity: stable
- function: graphics, ui-components, developer-tools
- domain: web-development, graphics, frontend
- platform: browser
- tags: webgl, webgl2, 3d-graphics, shaders, canvas, helper-library, javascript, web
