Particle systems allow us to simulate different real world phenomena like clouds, fog, and water. However, it can be very time consuming and difficult to build particle systems from scratch. Fortunately, there are two common open source particle engines we can use: the Flint and Stardust particle engines. They are similar to Papervision3D because they can help us to minimize the mathematics and scripts required to build particle effects. In this blog, we will use Stardust as an example to build a word in ActionScript 3 using particles.
