  • If you calculate the transformation you end up with <math>\begin{bmatrix} x \\ y \\ w \end{bmatrix}</math> where w is a value that you can discard if you are only interested in the (x,y) transformation. +Affine transformations are represented by transformation matrices that are one higher dimension than the regular transformations.
