all axes, this means the scaling factor is the same for every axis whether in 2D or 3D, this
is known as uniform scale.
Figure 20- Uniform scaling in
A scale factor of 1, means that the shape will retain its original size. While uniform scaling
preserves the shape of the object, non-uniform scale will change it by stretching towards a
side, or shrinking the shape disproportionately.

Scale is a linear transformation and can also be represented in matrix form.
