Class DLParticle

java.lang.Object
  de.rico.engine.effect.particle.AbstractParticle
      de.rico.engine.effect.particle.DLParticle

public class DLParticle
extends AbstractParticle

This class represents a particle used as part of a particle system to produce graphical effects. It is realized as a display list. Note: Display list particles (DLParticle) can be slower than directly drawn particles (DDParticle). I suppose thuis is due to the need to create a dislplay list for everey particle.
