The Miura fold is a form of rigid origami, meaning that the fold can be carried out by a continuous motion in which, at each step, each parallelogram is completely flat. This property allows it to be used to fold surfaces made of rigid materials, making it distinct from the Kresling fold and Yoshimura fold which cannot be rigidly folded and ...
The goal is to transform a flat square sheet of paper into a finished sculpture through folding and sculpting techniques. Modern origami practitioners generally discourage the use of cuts, glue, or markings on the paper. Origami folders often use the Japanese word kirigami to refer to designs which use cuts.
Modular origami or unit origami is a multi-stage paper folding technique in which several, or sometimes many, sheets of paper are first folded into individual modules or units and then assembled into an integrated flat shape or three-dimensional structure, usually by inserting flaps into pockets created by the folding process. [3]
The corners of a sheet of paper are folded up to meet the opposite sides and (if the paper is not already square) the top is cut off, making a square sheet with diagonal creases. [1] The four corners of the square are folded into the center, forming a shape known in origami terminology as a blintz base or cushion fold. [2]
It is, however, still origami, although origami purists frown upon threading or gluing the units together, while others recognize that early traditional Japanese origami often used both cutting (see thousand origami cranes or senbazuru) and pasting, and respect kusudama as an ingenious traditional paper folding craft in the origami world.
A quilled basket of flowers. Paper craft is a collection of crafts using paper or card as the primary artistic medium for the creation of two or three-dimensional objects. . Paper and card stock lend themselves to a wide range of techniques and can be folded, curved, bent, cut, glued, molded, stitched, or layere
Jun Maekawa (前川 淳, Maekawa Jun, 1958-) is a Japanese software engineer, mathematician, and origami artist. He is known for popularizing the method of utilizing crease patterns in designing origami models, with his 1985 publication Viva Origami, as well as other paperfolding-related theorems and mathematical analysis.
In 1996, Marshall Bern and Barry Hayes showed that the problem of assigning a crease pattern of mountain and valley folds in order to produce a flat origami structure starting from a flat sheet of paper is NP-complete. [18] In 1999, a theorem due to Haga provided constructions used to divide the side of a square into rational fractions. [19] [20]
