Due to
the simplicity of the particle distribution is also easy to
apply motion (Motion-blur)7, which is the diffuse effect
caused by the rapid movement of an object in the scene.
Many classical techniques ignore this step causing diffuse
effect (aliasing) of the edges of objects that move quickly
on the scene, like a train or plane. In addition, particle
systems model objects that are "alive" (change over time),
which is quite difficult to model with surface-based
techniques due to the difficulty of incorporating complex
dynamics.
