A [[Transformation]] that maps [[View Space|Camera Space]] to [[Device Space]].
Because [[View Space|Camera Space]] is [[Canonical]], therefore centered at the [[Origin]], all you need to do is [[../Math/Resize Transformation|scale]] the the width and height of the [[Camera Modeling Transform (2D)|Camera]]
$\huge
\mathcal \Delta =
S_{\braket{\frac{1}{{w}}, \frac{1}{h}}}
