## What it is
lightgl.js is a lightweight JavaScript library that wraps WebGL to make it easier to quickly prototype 3D graphics applications in the browser. It provides a low-level API with OpenGL-style conveniences like a modelview/projection matrix stack, built-in GLSL uniforms, and immediate mode, without a scene graph.

## Use cases
- prototype WebGL 3D graphics in the browser
- draw rotating cubes and meshes with shaders
- render to a texture
- implement a first-person camera
- use OpenGL immediate mode in JavaScript
- learn WebGL and shader programming

## When to choose
- you want a minimal, low-level WebGL wrapper without a scene graph
- you're prototyping or learning WebGL/OpenGL concepts
- you prefer OpenGL-style matrix stacks and immediate mode

## When to avoid
- you need a full 3D engine with scene graphs, lighting, and asset pipelines
- you want an actively maintained library with modern WebGL2/WebGPU support
- you need high-level abstractions like Three.js provides

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, game-engine
- domain: graphics, web-development
- platform: browser
- tags: webgl, opengl, 3d-graphics, shaders, matrix-math, prototyping, game-development, javascript, web
