A single point perspective, where you look at a railroad track, that’s one system. Two-point perspective is when you have two-point perspective. Cezanne’s paintings have eight or nine perspectives, various views of the same still life viewed from several angles and trying to incorporate that into one. Chinese perspective — which is the opposite of one-point perspective — where instead of the railroad tracks vanishing, they’re coming into you. And to orchestrate those into one entity is a wonderful challenge and a great treat to fool around with, mostly unsuccessfully, but wonderfully exciting.
