| Geological processes exhibit a multitude of hierarchies: techtonics,
sedementation, erosion. |
| Little surprise, then, that mountains have fractal and multifractal
characteristics. |
| Careful
tuning of random models to match observed numerical characteristics of real mountains
has led to natural-looking pictures of artificial mountains. |
| As mentioned in
Forgeries of Nature, we note three
ages of fractal landscapes. |
|
| Despite increasing realism, these simulations have not become
much larger files. |
| Fractal and multifractal approaches appear to capture something
of the essence of complicated physical processes. |
| The success of these simulations
is strong evidence of this claim. |
