Overview

Defines a particle renderer. Depending on the graphics system used to render the particle effects, you can implement either one single renderer per emitter that does the drawing implement a renderer per particle.

Class Method Details

.for(_particle) ⇒ Object

Factory method to provide a renderer for a particle. Called once per particle. The particle system does not care if the factory returns a shared renderer for all the particles or if it returns one per particle. Each particle will be associated with the renderer.
