This is a demo of a 3D particle emitter. particles emit from the mouse cursor at a rate of 20 particles per second. Each particle is given a random initial velocity in the x, y, and z coordinates. Each particle is affected by gravity and will collide with the floor plane and be destroyed. The demo uses 20 sprites so a system is used to reuse particle sprites as they become available.
