Parallel Projections - Transformations and Projections in Computer Graphics - page 65

Axonometric and oblique projections are generally considered different, but Fig-
ure 2.15 shows that the difference between them is a matter of taste and terminology. If
we rotate the object and light rays of the oblique projection 45 ◦ counterclockwise, the
result on the projection plane is identical to the axonometric projection.

She could afterward calmly discuss with him such
blameless technicalities as hidden line algorithms and
buffer refresh times, cabinet versus cavalier projections
and Hermite versus Bezier parametric cubic curve forms.
