Examples of fractal surfaces obtained through the random midpoint displacement method.

<p>These are surfaces () for different values of the Hurst exponent . For easier visualization, we have scaled the height of the surfaces in order to stay between and . We note that for small values of the surfaces display an alternation of peaks and valleys (anti-persistent behavior) much more frequent than those one obtained for larger values of . For larger values of , the surfaces are smoother reflecting the persistent behavior induced by the value of .
