-From this point on, assume that we will work in homogeneous coordinates, unless stated otherwise. We will drop the $h$ index, so any point $P$ or $P'$ can be assumed to be in homogeneous coordinates. As seen from Equation~\ref{eq:homogeneous}, we can represent the relationship between a point in 3D space and its image coordinates by a matrix vector relationship:
