## What it is
Three Nebula is a WebGL and WebGPU based 3D particle system engine designed to work alongside three.js. It provides emitters, initializers, and behaviours for creating GPU-accelerated particle effects from sprites or 3D meshes, with JSON-serializable system definitions.

## Use cases
- add particle effects to a three.js scene
- create fire, smoke, or explosion effects in the browser
- render tens of thousands of particles at 60fps
- design particle systems visually and export as JSON
- build 3D visual effects for web games
- animate sprites and meshes with particle behaviours

## When to choose
- you are already using three.js and need particle effects
- you need GPU-accelerated rendering of large particle counts
- you want portable, JSON-defined particle systems
- you prefer a declarative emitter/initializer/behaviour API

## When to avoid
- your project does not use three.js
- you need CPU-side particle physics or simulation outside the browser
- you need a standalone 2D particle engine for canvas or DOM

## Facets
