# 72 What does aliasing have to do with fractals?

Fractals, are very strange objects indeed. Because they have

an infinite amount of arbitrarily small detail embedded inside them,

they have an infinite number of frequencies in the images. When we use

a program to compute an image of a fractal, each pixel in the image is

actually a sample of the fractal. Because the fractal itself has

arbitrarily high frequencies inside it, we can never sample high

enough to reveal the "true" nature of the fractal. "Every" fractal

ever computed has aliasing in it. (A special kind of aliasing is

called "Moire' patterns" and are often visible in fractals as well.)
