Fig. 2. Examples of objects with Euclidian and Fractal (non-integer) dimensions (adapted from Milne, 1997). Fractal and Euclidean geometry differ in that fractals do not require the value of dimensions (d) to be integers. Instead, they can be fractional values. For instance, if a cube was made of Swiss cheese, it would not completely fill the three-dimensional space. Instead of d assuming a value of three, the fractal dimension of the Swiss cheese cube would fall between two and three.
