JavaScript Particle System

22 Dec 2009 | By Alex Young | Tags graphics animation

After yesterday’s Processing.js article I discovered this post about creating a particle system with JavaScript and a canvas: Parcycle: A Particle System with HTML5 canvas.

You can view the effect in action in this demo: Parcycle

I found the use of globalCompositeOperation very interesting in this code. It allowed the author to make particles appear lighter when they overlap by using a drawing mode rather than detecting the colour on the canvas.
