- This renderer is a ´hacky´ solution to display geometry-based particles. It pre-creates a
number of SceneNodes (childs of the parent Node to which the ParticleSystem is attached) and
Entities and uses these pools to display the particles. There are better solutions, but
this one is simple and fast enough, although it has some drawbacks.
- Future solutions should rather make use of hardware instancing to display a large number of
geometry-based particles at once.
