    Any prim in Second Life can emit particles. Particles are 2D sprites emitted from their prim in definable ways. Particles are objects in the sense that they can be touched or count against the land's maximum object count. Particles are generated completely on the client side, so they do not contribute to in-game lag.

    Particle emitters are used for a wide range of purposes in Second Life. Some of their uses include:

• Creating insects and leaves in landscaped areas
• Creating flashy laser type effects in clubs
• Leaving smoke and wave trails behind vehicles
• Causing jewelry to sparkle
• Smoke from chimneys
• Creating explosions

    This chapter provides several recipes for particle emitters. The first recipe shows a basic particle emitter script.
