A smooth column of smoke rising from a cigarette quickly turns into turbulent, nondeterministic flow. You could easily represent the smooth column as a line, but nothing in Euclidean geometry is useful for modeling turbulent smoke. In fact, in the real world—as opposed to the virtual world of games—most physical phenomena exhibit chaotic behavior that can be challenging to represent graphically.

One way to represent chaotic physical systems, such as turbulent smoke or explosions, is to display a sequence of images; for example, Snail Bait implements explosions ...
