What Do the Cginnese Call the Art of Folding Oaoer

Traditional Japanese art of paper folding

The folding of an Origami crane

Origami ( 折り紙 , Japanese pronunciation: [oɾiɡami] or [oɾiꜜɡami], from ori meaning "folding", and kami meaning "paper" (kami changes to gami due to rendaku)) is the art of newspaper folding, which is often associated with Japanese civilisation. In modern usage, the give-and-take "origami" is used every bit an inclusive term for all folding practices, regardless of their civilization of origin. The goal is to transform a flat square canvass 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 oftentimes utilize the Japanese word kirigami to refer to designs which apply cuts.

The small number of basic origami folds can exist combined in a diversity of means to make intricate designs. The best-known origami model is the Japanese paper crane. In general, these designs begin with a square sail of newspaper whose sides may be of different colors, prints, or patterns. Traditional Japanese origami, which has been practiced since the Edo period (1603–1867), has often been less strict most these conventions, sometimes cutting the paper or using nonsquare shapes to showtime with. The principles of origami are also used in stents, packaging, and other engineering applications.^{[1] [2]}

History

The folding of two origami cranes linked together, from the start known volume on origami, Hiden senbazuru orikata, published in Nihon in 1797

Distinct paperfolding traditions arose in Europe, China, and Nippon which have been well-documented by historians. These seem to accept been by and large dissever traditions, until the 20th century.

In Cathay, traditional funerals oft include the called-for of folded paper, well-nigh often representations of gold nuggets (yuanbao). The exercise of burning paper representations instead of total-scale wood or clay replicas dates from the Song Dynasty (905–1125 CE), though it is not clear how much folding was involved.^[iii]

In Japan, the primeval unambiguous reference to a paper model is in a short poem by Ihara Saikaku in 1680 which mentions a traditional butterfly design used during Shinto weddings.^[4] Folding filled some ceremonial functions in Edo period Japanese civilization; noshi were attached to gifts, much like greeting cards are used today. This developed into a grade of entertainment; the get-go two instructional books published in Nihon are clearly recreational.

In Europe, there was a well-adult genre of napkin folding, which flourished during the 17th and 18th centuries. Later on this period, this genre declined and was by and large forgotten; historian Joan Sallas attributes this to the introduction of porcelain, which replaced circuitous napkin folds as a dinner-table status symbol amidst nobility.^[v] However, some of the techniques and bases associated with this tradition continued to be a office of European civilisation; folding was a meaning part of Friedrich Fröbel'southward "Kindergarten" method, and the designs published in connection with his curriculum are stylistically similar to the napkin fold repertoire. Another case of early on origami in Europe is the "pajarita," a stylized bird whose origins date from at least the nineteenth century.^[half-dozen]

When Nippon opened its borders in the 1860s, every bit office of a modernization strategy, they imported Fröbel'southward Kindergarten system—and with it, German ideas about paperfolding. This included the ban on cuts, and the starting shape of a bicolored square. These ideas, and some of the European folding repertoire, were integrated into the Japanese tradition. Earlier this, traditional Japanese sources use a variety of starting shapes, oftentimes had cuts; and if they had colour or markings, these were added later on the model was folded.^[seven]

In the early on 1900s, Akira Yoshizawa, Kosho Uchiyama, and others began creating and recording original origami works. Akira Yoshizawa in detail was responsible for a number of innovations, such as wet-folding and the Yoshizawa–Randlett diagramming system, and his work inspired a renaissance of the art form.^[8] During the 1980s a number of folders started systematically studying the mathematical properties of folded forms, which led to a rapid increment in the complexity of origami models.^[nine]

Starting in the tardily 20th century, at that place has been a renewed interest in understanding the beliefs of folding matter, both artistically and scientifically. The "new origami," which distinguishes it from onetime arts and crafts practices, has had a rapid evolution due to the contribution of computational mathematics and the evolution of techniques such as box-pleating, tessellations and wet-folding. Artists like Robert J. Lang, Erik Demaine, Sipho Mabona, Giang Dinh, Paul Jackson, and others, are often cited for advancing new applications of the art. The computational facet and the interchanges through social networks, where new techniques and designs are introduced, have raised the profile of origami in the 21st century.^{[x] [11] [12]}

Techniques and materials

Techniques

A listing of 9 basic origami folds: the valley (or mountain), the pleat, the rabbit ear, the outside reverse, the inside contrary, the crimp, the squash, the sink and the petal

Many origami books brainstorm with a description of basic origami techniques which are used to construct the models. This includes elementary diagrams of bones folds similar valley and mount folds, pleats, contrary folds, squash folds, and sinks. There are also standard named bases which are used in a wide diverseness of models, for instance the bird base of operations is an intermediate phase in the construction of the flapping bird.^[13] Additional bases are the preliminary base (square base), fish base, waterbomb base, and the frog base.^[xiv]

Origami newspaper

A crane and papers of the same size used to fold it

Most whatsoever laminar (apartment) fabric can be used for folding; the only requirement is that it should concord a crease.

Origami newspaper, often referred to as "kami" (Japanese for paper), is sold in prepackaged squares of various sizes ranging from 2.5 cm (1 in) to 25 cm (10 in) or more than. It is commonly colored on i side and white on the other; nevertheless, dual coloured and patterned versions exist and can exist used effectively for color-changed models. Origami paper weighs slightly less than copy newspaper, making it suitable for a wider range of models.

Normal copy newspaper with weights of lxx–xc g/m² (nineteen–24 lb) tin can exist used for simple folds, such equally the crane and waterbomb. Heavier weight papers of 100 g/chiliadⁱⁱ (approx. 25 lb) or more than can be moisture-folded. This technique allows for a more rounded sculpting of the model, which becomes rigid and sturdy when information technology is dry.

Foil-backed paper, as its proper name implies, is a sail of thin foil glued to a canvas of thin newspaper. Related to this is tissue foil, which is made by gluing a thin slice of tissue paper to kitchen aluminium foil. A second piece of tissue can be glued onto the opposite side to produce a tissue/foil/tissue sandwich. Foil-backed paper is available commercially, just not tissue foil; it must be handmade. Both types of foil materials are suitable for complex models.

Washi ( 和紙 ) is the traditional origami paper used in Japan. Washi is mostly tougher than ordinary paper made from wood pulp, and is used in many traditional arts. Washi is usually made using fibres from the bark of the gampi tree, the mitsumata shrub (Edgeworthia papyrifera), or the paper mulberry merely tin too be made using bamboo, hemp, rice, and wheat.

Artisan papers such as unryu, lokta, hanji^{[ citation needed ]}, gampi, kozo, saa, and abaca accept long fibers and are often extremely strong. As these papers are floppy to start with, they are often backcoated or resized with methylcellulose or wheat paste before folding. Also, these papers are extremely thin and compressible, assuasive for sparse, narrowed limbs equally in the case of insect models.

Paper money from various countries is also popular to create origami with; this is known variously equally Dollar Origami, Orikane, and Money Origami.

Tools

It is common to fold using a flat surface, but some folders similar doing it in the air with no tools, specially when displaying the folding.^{[ citation needed ]} Some folders believe that no tool should be used when folding.^{[ citation needed ]} Nevertheless a couple of tools can help peculiarly with the more circuitous models. For instance a bone folder allows abrupt creases to be made in the paper hands, paper clips tin deed equally extra pairs of fingers, and tweezers can be used to make minor folds. When making complex models from origami pucker patterns, information technology can assistance to use a ruler and ballpoint embosser to score the creases. Completed models tin exist sprayed then that they continue their shape improve, and a spray is needed when moisture folding.

Types

Action origami

In add-on to the more mutual still-life origami, there are as well moving object designs; origami can move. Action origami includes origami that flies, requires inflation to consummate, or, when complete, uses the kinetic energy of a person's hands, applied at a certain region on the model, to move another flap or limb. Some debate that, strictly speaking, just the latter is really "recognized" as activeness origami. Activeness origami, get-go appearing with the traditional Japanese flapping bird, is quite mutual. One example is Robert Lang'due south instrumentalists; when the figures' heads are pulled away from their bodies, their hands will movement, resembling the playing of music.

Modular origami

Modular origami consists of putting a number of identical pieces together to class a complete model. Often the individual pieces are simple, but the last assembly may exist more difficult. Many modular origami models are decorative folding balls such as kusudama, which differ from classical origami in that the pieces may be held together using thread or glue.

Chinese paper folding, a cousin of origami, includes a similar way called gilded venture folding where big numbers of pieces are put together to create elaborate models. This style is most normally known as "3D origami". However, that proper noun did not appear until Joie Staff published a series of books titled 3D Origami, More 3D Origami, and More and More than 3D Origami.^{[ citation needed ]} This fashion originated from some Chinese refugees while they were detained in America and is besides called Aureate Venture folding from the ship they came on.^{[ commendation needed ]}

Wet-folding

Wet-folding is an origami technique for producing models with gentle curves rather than geometric straight folds and flat surfaces. The newspaper is dampened so it can be moulded easily, the final model keeps its shape when it dries. Information technology tin can be used, for instance, to produce very natural looking animal models. Size, an adhesive that is crisp and hard when dry, but dissolves in water when wet and becoming soft and flexible, is often applied to the paper either at the pulp stage while the newspaper is being formed, or on the surface of a prepare canvas of paper. The latter method is called external sizing and nigh commonly uses Methylcellulose, or MC, paste, or various plant starches.

Pureland origami

Pureland origami adds the restrictions that only simple mountain/valley folds may exist used, and all folds must accept straightforward locations. Information technology was developed by John Smith in the 1970s to help inexperienced folders or those with limited motor skills. Some designers also like the claiming of creating within the very strict constraints.

Origami tessellations

Origami tessellation is a branch that has grown in popularity subsequently 2000. A tessellation is a drove of figures filling a aeroplane with no gaps or overlaps. In origami tessellations, pleats are used to connect molecules such every bit twist folds together in a repeating fashion. During the 1960s, Shuzo Fujimoto was the first to explore twist fold tessellations in any systematic way, coming upward with dozens of patterns and establishing the genre in the origami mainstream. Around the same time period, Ron Resch patented some tessellation patterns every bit part of his explorations into kinetic sculpture and developable surfaces, although his piece of work was not known by the origami community until the 1980s. Chris Palmer is an artist who has extensively explored tessellations after seeing the Zilij patterns in the Alhambra, and has found ways to create detailed origami tessellations out of silk. Robert Lang and Alex Bateman are two designers who use computer programs to create origami tessellations. The first international convention devoted to origami tessellations was hosted in Brasília (Brazil) in 2006,^[15] and the first pedagogy book on tessellation folding patterns was published past Eric Gjerde in 2008.^[16] Since then, the field has grown very speedily. Tessellation artists include Polly Verity (Scotland); Joel Cooper, Christine Edison, Ray Schamp and Goran Konjevod from the Us; Roberto Gretter (Italia); Christiane Bettens (Switzerland); Carlos Natan López (Mexico); and Jorge C. Lucero (Brazil).

Kirigami

Kirigami is a Japanese term for paper cutting. Cutting was oftentimes used in traditional Japanese origami, just modern innovations in technique have made the apply of cuts unnecessary. Most origami designers no longer consider models with cuts to be origami, instead using the term Kirigami to describe them. This change in attitude occurred during the 1960s and 70s, so early origami books often use cuts, only for the virtually part they have disappeared from the modern origami repertoire; most modern books don't even mention cut.^[17]

Strip folding

Strip folding is a combination of paper folding and paper weaving.^[18] A common case of strip folding is chosen the Lucky Star, as well called Chinese lucky star, dream star, wishing star, or only origami star. Another common fold is the Moravian Star which is fabricated past strip folding in three-dimensional design to include 16 spikes.^[18]

Teabag folding

Example of folded "tea handbag" paper

Teabag folding is credited to Dutch artist Tiny van der Plas, who developed the technique in 1992 as a papercraft fine art for embellishing greeting cards. It uses small square pieces of paper (e.g., a tea bag wrapper) bearing symmetrical designs that are folded in such a way that they interlock and produce a 3-dimensional version of the underlying design. The basic kite fold is used to produce rosettes that are a 3 dimensional version of the 2D blueprint.

The bones rosette design requires eight matching squares to be folded into the 'kite' design. Mathematics teachers detect the designs very useful as a practical way of demonstrating some bones backdrop of symmetry.^{[ citation needed ]}

Mathematics and technical origami

Mathematics and practical applications

Jump Into Action, designed past Jeff Beynon, made from a unmarried rectangular piece of paper^[xix]

The do and study of origami encapsulates several subjects of mathematical interest. For instance, the problem of flat-foldability (whether a crease blueprint can be folded into a ii-dimensional model) has been a topic of considerable mathematical study.

A number of technological advances take come from insights obtained through paper folding. For example, techniques accept been adult for the deployment of car airbags and stent implants from a folded position.^[20]

The problem of rigid origami ("if nosotros replaced the newspaper with sheet metallic and had hinges in place of the crease lines, could we yet fold the model?") has great practical importance. For example, the Miura map fold is a rigid fold that has been used to deploy large solar panel arrays for space satellites.

Origami tin can be used to construct various geometrical designs not possible with compass and straightedge constructions. For instance paper folding may be used for angle trisection and doubling the cube.

Technical origami

Technical origami, known in Japanese as origami sekkei ( 折り紙設計 ), is an origami design approach in which the model is conceived as an engineered crease blueprint, rather than developed through trial-and-error. With advances in origami mathematics, the basic structure of a new origami model tin be theoretically plotted out on newspaper earlier any bodily folding fifty-fifty occurs. This method of origami pattern was developed past Robert Lang, Meguro Toshiyuki and others, and allows for the creation of extremely complex multi-limbed models such as many-legged centipedes, homo figures with a full complement of fingers and toes, and the similar.

The crease blueprint is a layout of the creases required to form the structure of the model. Paradoxically plenty, when origami designers come up upwardly with a crease design for a new design, the majority of the smaller creases are relatively unimportant and added but towards the completion of the model. What is more than important is the allocation of regions of the paper and how these are mapped to the construction of the object existence designed. By opening up a folded model, you tin can observe the structures that comprise it; the report of these structures led to a number of crease-design-oriented design approaches

The blueprint of allocations is referred to as the 'circle-packing' or 'polygon-packing'. Using optimization algorithms, a circle-packing effigy tin can be computed for any uniaxial base of arbitrary complication.^[21] One time this figure is computed, the creases which are then used to obtain the base construction can be added. This is not a unique mathematical process, hence information technology is possible for two designs to take the same circle-packing, and even so different crease pattern structures.

As a circle encloses the maximum amount of area for a given perimeter, circumvolve packing allows for maximum efficiency in terms of paper usage. Nonetheless, other polygonal shapes can exist used to solve the packing problem as well. The employ of polygonal shapes other than circles is often motivated by the want to detect easily locatable creases (such as multiples of 22.v degrees) and hence an easier folding sequence also. One popular offshoot of the circle packing method is box-pleating, where squares are used instead of circles. As a event, the crease design that arises from this method contains only 45 and 90 caste angles, which oftentimes makes for a more direct folding sequence.

A number of reckoner aids to origami such as TreeMaker and Oripa, have been devised.^[22] TreeMaker allows new origami bases to be designed for special purposes^[23] and Oripa tries to calculate the folded shape from the pucker pattern.^[24]

Ethics and copyright

Copyright in origami designs and the use of models has get an increasingly of import upshot in the origami customs, as the internet has fabricated the auction and distribution of pirated designs very easy.^[25] It is considered practiced etiquette to always credit the original artist and the folder when displaying origami models. It has been claimed that all commercial rights to designs and models are typically reserved by origami artists; however, the degree to which this can be enforced has been disputed. Under such a view, a person who folds a model using a legally obtained design could publicly display the model unless such rights were specifically reserved, whereas folding a blueprint for coin or commercial employ of a photo for example would require consent.^[26] The Origami Authors and Creators group was set up to represent the copyright interests of origami artists and facilitate permissions requests.

Withal, a court in Japan has asserted that the folding method of an origami model "comprises an idea and non a creative expression, and thus is not protected under the copyright police".^[27] Further, the court stated that "the method to folding origami is in the public domain; one cannot avoid using the same folding creases or the same arrows to show the direction in which to fold the paper". Therefore, it is legal to redraw the folding instructions of a model of some other author even if the redrawn instructions share similarities to the original ones, as long as those similarities are "functional in nature". The redrawn instructions may exist published (and even sold) without necessity of any permission from the original writer.
