Comparing The Rough With The Smooth. Comparing The Rough With The Smooth. They can be used to construct mathematical pictures that look like snow flakes , fern leaves , clouds , mountains , or moonscapes . Therefore, they are often the method of choice for producing images of natural phenomena in computer-generated films. In the first two examples, surface roughness plays a major role in determining physical properties.
Rainfall reduces the roughness of soil surfaces.
Its effect may be quantified by analyzing measurements of surface height both before and after rain. Different manufacturing processes produce plastic food wrap with different levels of roughness. The process that gives the smoothest surface may be determined by estimating fractal-dimension. Let me say a little about the plastic food-wrap problem. They also help quantify the reliability of these estimates.
