It is based on the [Proton](https://github.com/drawcall/Proton) Engine library. It inherited Proton's most api.
\nI think it is the simplest three.js particle engine.Check out examples at [https://drawcall.github.io/three.proton/](https://drawcall.github.io/three.proton/)
\n\n```shell\nnpm install three three.proton.js\n```\n\n## Features\n- Four kinds of renderers\n - MeshRender \n - SpriteRender \n - PointsRender \n - CustomRender \n\n- Three kinds of emitters which can simulate many different physical effects\n - Emitter \n - BehaviourEmitter \n - FollowEmitter \n \n- Perfectly compatible with the three.js library. \n\n## Demo\n\n

\n These demos are real, you can click them! They contain the full code, too.\n

\n\n## Installation\n\n#### Import library\n\n```javascript\nimport * as THREE from 'three';\nimport Proton from 'three.proton.js';\n```\n\n#### Include in html\n```javascript\n \n \n```\n\n## Usage\n```javascript\nvar proton = new Proton();\nvar emitter = new Proton.Emitter();\n\n//setRate\nemitter.rate = new Proton.Rate(new Proton.Span(4, 16), new Proton.Span(.01));\n\n//addInitialize\nemitter.addInitialize(new Proton.Position(new Proton.PointZone(0, 0)));\nemitter.addInitialize(new Proton.Mass(1));\nemitter.addInitialize(new Proton.Radius(6, 12));\nemitter.addInitialize(new Proton.Life(3));\nemitter.addInitialize(new Proton.V(45, new Proton.Vector3D(0, 1, 0), 180));\n\n//addBehaviour\nemitter.addBehaviour(new Proton.Alpha(1, 0));\nemitter.addBehaviour(new Proton.Scale(.1, 1.3));\n\nvar color1 = new THREE.Color();\nvar color2 = new THREE.Color();\nvar colorBehaviour = new Proton.Color(color1, color2);\nemitter.addBehaviour(colorBehaviour);\nemitter.emit();\n\n//add emitter\nproton.addEmitter(emitter);\n\n//add renderer\nproton.addRender(new Proton.SpriteRender(scene));\n```\n\n## Building three.proton\nNode is a dependency, use terminal to install it with with:
