three.proton

three.proton is a magical 3d particle engine using three.js. It is based on the Proton Engine library. It inherited Proton's most Api, and it was very, very easy to use.
I think it is the simplest three.js particle engine.Check out examples at https://a-jie.github.io/three.proton/

Features

• Four kinds of renderers

  • MeshRender
  • SpriteRender
  • PointsRender
  • CustomRender

• Three kinds of emitters which can simulate many different physical effects

  • Emitter
  • BehaviourEmitter
  • FollowEmitter

• Perfectly compatible with the three.js library.

Usage

var proton = new Proton();
var emitter = new Proton.Emitter();

//setRate
emitter.rate = new Proton.Rate(new Proton.Span(4, 16), new Proton.Span(.01));

//addInitialize
emitter.addInitialize(new Proton.Position(new Proton.PointZone(0, 0)));
emitter.addInitialize(new Proton.Mass(1));
emitter.addInitialize(new Proton.Radius(6, 12));
emitter.addInitialize(new Proton.Life(3));
emitter.addInitialize(new Proton.V(45, new Proton.Vector3D(0, 1, 0), 180));

//addBehaviour
emitter.addBehaviour(new Proton.Alpha(1, 0));
emitter.addBehaviour(new Proton.Scale(.1, 1.3));

var color1 = new THREE.Color();
var color2 = new THREE.Color();
var colorBehaviour = new Proton.Color(color1, color2);
emitter.addBehaviour(colorBehaviour);
emitter.emit();

//add emitter
proton.addEmitter(emitter);

//add renderer
proton.addRender(new Proton.SpriteRender(scene));
