Crease Pattern Validation Origami. Origami structures morph between 2d and 3d conformations along predetermined fold lines that efficiently program the form, function and mobility of the structure. A crease pattern is a division of the unit square into a finite set of polygonal regions by a set of straight line segments.
To the designer, they provide a structural representation of the artwork. The lines indicate creases in the folded design. These basic structures include triangular hollow beams, flexural revolute joints, key.
