* by collision detection, in our case it is the camera. The third defines how big
* the object is, it is the radius of an ellipsoid. Try it out and change the radius
* to smaller values, the camera will be able to move closer to walls after this.
* The next parameter is the direction and speed of gravity. You could set it to
* (0,0,0) to disable gravity. And the last value is just a translation: Without
* this, the ellipsoid with which collision detection is done would be around
* the camera, and the camera would be in the middle of the ellipsoid. But as
* human beings, we are used to have our eyes on top of the body, with which
* we collide with our world, not in the middle of it. So we place the scene

* emitters are quite flexible and usually have lots of parameters like
* direction, amount and color of the particles they should create.
* There are different emitters, for example a point emitter which lets
* particles pop out at a fixed point. If the particle emitters available
* in the engine are not enough for you, you can easily create your own ones,
* you'll simply have to create a class derived from the IParticleEmitter
* interface and attach it to the particle system using setEmitter().
* In this example we create a box particle emitter, which creates particles
* randomly inside a box. The parameters define the box, direction of the
* articles, minimal and maximal new particles per second, color and minimal
* and maximal livetime of the particles. Because only with emitters particle
* system would be a little bit boring, there are particle affectors, which
* modify particles during they fly around. They can be added to the particle
* system, simulating additional effects like gravity or wind. The particle
* affector we use in this example is an affector, which modifies the color
* of the particles: It lets them fade out. Like the particle emitters,
* additional particle affectors can also be implemented by you, simply derive
* a class from IParticleAffector and add it with addAffector(). After we set
* a nice material to the particle system, we have a cool looking camp fire.
* By adjusting material, texture, particle emitter and affector parameters,
* it is also easily possible to create smoke, rain, explosions, snow, and
