2° + 3° crease patterns
here's your chance to compare the complexities of a 2° and a 3° model.
on the left you see the cp of the classic miura-ori pattern.
on the right you see the cp of the 3° parallel pattern.
the 3° parallel pattern develops from the miura ori by another set of pleats which appear as horizontal creases in the pattern. also, note how some of the 2° pleats change from mountain to valley or the other way around.
