For example, a dilation with scale factor 3 / 2 and center point P maps each point X to an image point X’, so that PX’ = 3 / 2 PX. Then two geometric figures are similar, with scale factor k if there is some composite of dilation and rigid motion transformations that maps one figure exactly on top of the other. The scaling is uniform if and only if the scaling factors are equal (v x = v y = v z). If all except one of the scale factors are equal to 1, we have directional scaling. In the case where v x = v y = v z = k, the scaling is also called an enlargement or dilation by a factor k, increasing the area by a factor of k 2 and the volume by a factor ... image of line p after a dilation with center at the origin and a scale factor of 2.
