Origamic architecture is a form of kirigami that involves the three-dimensional reproduction of architecture and monuments, on various scales, using cut-out and folded paper, usually thin paperboard. Visually, these creations are comparable to intricate 'pop-ups', indeed, some works are deliberately engineered to possess 'pop-up'-like properties. However, origamic architecture tends to be cut out of a single sheet of paper, whereas most pop-ups involve two or more. To create the three-dimensional image out of the two-dimensional surface requires skill akin to that of an architect.
The development of origamic architecture began with Professor Masahiro Chatani's (then a newly appointed professor at the Tokyo Institute of Technology) experiments with designing original and unique greeting cards. [1] Japanese culture encourages the giving and receiving of cards for various special occasions and holidays, particularly the Japanese New Year, and according to his own account, Professor Chatani personally felt that greeting cards were a significant form of connection and communication between people. He worried that in today's fast-paced modern world, the emotional connections called up and created by the exchange of greeting cards would become scarce. [2]
In the early 1980s, Professor Chatani began to experiment with cutting and folding paper to make unique and interesting pop-up cards. He used the techniques of origami (Japanese paper folding) and kirigami (Japanese papercutting), as well as his experience in architectural design, to create intricate patterns that played with light and shadow. [3] Many of his creations are made of stark white paper which emphasizes the shadowing effects of the cuts and folds. In the preface to one of his books, he called the shadows of the three-dimensional cutouts a "dreamy scene" that invited the viewer into a "fantasy world". [3]
At first, Professor Chatani simply gave the cards to his friends and family. Over the next nearly thirty years, however, he published over fifty books on origamic architecture, many directed at children. He came to believe that origamic architecture could be a good way to teach architectural design and appreciation of architecture, as well as to inspire interest in mathematics, art, and design in young children. [3]
Professor Chatani also spent a good deal of time travelling, even after his retirement, to exhibit his work. He frequently collaborated on books and exhibits with Keiko Nakazawa and Takaaki Kihara. [4]
Masahiro Chatani was a Japanese architect (certified, first class) and professor considered to be the creator of origamic architecture. From its development until his death in 2008, he was widely acknowledged to be the world's foremost origamic architect.
Masahiro Chatani was born in Hiroshima, Japan in 1934. He grew up in Tokyo, and graduated from the Tokyo Institute of Technology in 1956. He became an assistant professor at the Tokyo Institute of Technology in 1969 and an associated assistant professor at Washington University in 1977, and was promoted to full professorship at the Tokyo Institute of Technology in 1980. It was around this time that he created what is now known as "origamic architecture". He became a professor emeritus fifteen years later, and continued to lecture at a number of institutions, including the Japan Architectural College, Hosei University, and the Shizuoka University of Art and Architecture. [5] After his retirement from active professorship, he continued to travel around the world, giving exhibits, demonstrations, and seminars on architectural design and origamic architecture. [2]
Professor Chatani died on November 19, 2008, at the age of 74, from complications from laryngeal cancer. [6]
There are several different styles of origamic architecture. In one style, a folded paper is cut in such a way that when the paper is opened to form a 90-degree angle, a three-dimensional image can be created, similar to most pop-up books. [7] A second style requires attaching a cut-out form to a base sheet of paper with thread.
Takaaki Kihara frequently uses another technique in which the three-dimensional structure is "punched out" of the flat card. [7] Designs created with this technique allow the viewer to see the empty cutouts, which can create interesting shadowing effects. Kihara also points out that this style of origamic architecture is easier to store than the other 180-degree form, as the cut-out three-dimensional forms can be re-flattened with ease. [7]
Less commonly, some designs require opening the paper and folding it completely in the opposite direction, making a 360-degree angle. [4]
Origamic architecture has become a tool many architects use to visualize the 2D as 3D in order to expand and explore on a design idea. [8] 3D origami objects can be used in the interior design, i.e. for decorating walls. [9] There are ways of doing origamic architecture using CAD (Computer-Aided-Design). CAD uses laser cuts to speed the cutting process along allowing for precise forms to be made. AI design programs still are in development, architects have been searching for solutions to their design struggles. [10]
EPFL architects Hani Buri and Yves Weinand, researched ways to mass produce "complex folded plate structures using origami architecture. [11] Through different folding techniques like the Yoshimura pattern (an inverted diamond pattern), Miura Ori pattern (a repetition of reverse folds resulting in a diamond pattern), and the Diagonal pattern (series of parallelograms folded at a diagonal) [11] - all were very successful due to their Origami diamond and herringbone patterns. As a result Buri and Weinand were able to produce successful models and even a Chapel in Lausanne, Switzerland.
A study performed at the University of Pennsylvania in 2014, laid out the rules for folding and cutting a hexagonal lattice into a variety of three-dimensional shapes. [12]
Although origamic architecture was developed and first gained popularity in Japan, it is today practiced in countries all over the world. [13]
Some leading practitioners include Masahiro Chatani (Japan), Keiko Nakazawa (Japan), Takaaki Kihara (Japan), Ingrid Siliakus (Netherlands), María Victoria Garrido (Argentina), Giovanni Russo (Italy) and Marc Hagan-Guirey (UK). [14] [15] [16]
Origami is the Japanese art of paper folding. In modern usage, the word "origami" is often used as an inclusive term for all folding practices, regardless of their culture of origin. 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.
The discipline of origami or paper folding has received a considerable amount of mathematical study. Fields of interest include a given paper model's flat-foldability, and the use of paper folds to solve up-to cubic mathematical equations.
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. These insertions create tension or friction that holds the model together. Some assemblies can be somewhat unstable because adhesives or string are not used.
The art of paper cutting in China may date back to the 2nd century CE, when paper was invented by Cai Lun, a court official of the Eastern Han dynasty.
A paper plane is a toy aircraft, usually a glider, made out of single folded sheet of paper or paperboard. It typically takes the form of a simple nose-heavy triangle thrown like a dart.
Akira Yoshizawa was a Japanese origamist, considered to be the grandmaster of origami. He is credited with raising origami from a craft to a living art. According to his own estimation made in 1989, he created more than 50,000 models, of which only a few hundred designs were presented as diagrams in his 18 books. Yoshizawa acted as an international cultural ambassador for Japan throughout his career. In 1983, Emperor Hirohito awarded him the Order of the Rising Sun, 5th class, one of the highest honors bestowed in Japan.
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 layered. Papermaking by hand is also a paper craft.
Kirigami is a variation of origami, the Japanese art of folding paper. In kirigami, the paper is cut as well as being folded, resulting in a three-dimensional design that stands away from the page. Kirigami typically does not use glue.
The history of origami followed after the invention of paper and was a result of paper's use in society. In the detailed Japanese classification, origami is divided into stylized ceremonial origami and recreational origami, and only recreational origami is generally recognized as origami. However, this page describes the history of both ceremonial and recreational origami.
Papercutting or paper cutting is the art of paper designs. Art has evolved all over the world to adapt to different cultural styles. One traditional distinction most styles share is that the designs are cut from a single sheet of paper as opposed to multiple adjoining sheets as in collage.
The crane is considered a mystical or holy creature in Japan and is said to live for a thousand years. That is why one thousand origami cranes are made, one for each year. In some stories, it is believed that the cranes must be completed within one year and they must all be made by the person who will make the wish at the end.
Origami paper is the paper used for origami, the art of Japanese paper folding. The only real requirement of the folding medium is that it must be able to hold a crease, but should ideally also be thinner than regular paper for convenience when multiple folds over the same small paper area are required.
Thomas C. Hull is an associate professor of applied mathematics at Franklin & Marshall College and is known for his expertise in the mathematics of paper folding.
Kawasaki's theorem or Kawasaki–Justin theorem is a theorem in the mathematics of paper folding that describes the crease patterns with a single vertex that may be folded to form a flat figure. It states that the pattern is flat-foldable if and only if alternatingly adding and subtracting the angles of consecutive folds around the vertex gives an alternating sum of zero. Crease patterns with more than one vertex do not obey such a simple criterion, and are NP-hard to fold.
Paper models, also called card models or papercraft, are models constructed mainly from sheets of heavy paper, paperboard, card stock, or foam.
Paper toys are constructed in several ways, by folding, as in paper airplanes, paper fortune tellers or Origami, or by cutting, decorating or assembling pieces of paper with glue or tape to create a paper doll or paper model.
Paper cut sculpture, a form of papercutting, is a contemporary development of a traditional art form. Instead of flat, two-dimensional pieces, the art is given a three-dimensional form. Different artists have used a variety of different methods. A notable example is Nahoko Kojima, a Japanese artist who utilised nylon threads to suspend individual large sheets of washi paper to form the bodies of animals and other natural figures.
