parallelX0 :: (R1 v, Num n) => Deformation v v n

The parallel projection onto the plane x=0

perspectiveX1 :: (R1 v, Functor v, Fractional n) => Deformation v v n

The perspective division onto the plane x=1 along lines going through the origin.

parallelY0 :: (R2 v, Num n) => Deformation v v n

The parallel projection onto the plane y=0

perspectiveY1 :: (R2 v, Functor v, Floating n) => Deformation v v n

The perspective division onto the plane y=1 along lines going through the origin.

facingX :: (R1 v, Functor v, Fractional n) => Deformation v v n

The viewing transform for a viewer facing along the positive X axis. X coördinates stay fixed, while Y coördinates are compressed with increasing distance. asDeformation (translation unitX) <> parallelX0 <> frustrumX = perspectiveX1

facingY :: (R2 v, Functor v, Fractional n) => Deformation v v n
