-{\bf TODO}
-\begin{itemize}
- \item Intermediate coordinate systems...
- \item Write Matrix operations properly
- \item Link with the results where applying \eqref{view-transformation} directly leads to disaster
- \item This is because for $v_w << 1$, an error of $1 ulp$ in $x - v_x$ is comparable with $v_w$, ie: Can increase to the order of the size of the display (or more)
-\end{itemize}
