DESCRIPTION:Origami\, the art of folding a sheet of paper into various for
 ms without stretching or cutting\, can be applied to structural engineerin
 g and design purposes. The applications include the forming of a 3D surfac
 e without assembling multiple parts and the construction of kinetic struct
 ures such as retractable roofs\, openings\, temporary shelters\, and space
  structures.\nA plate-and-hinge model of origami\, i.e.\, transformable po
 lyhedral surface\, is called "rigid origami".\nrigid origami is useful for
  designing kinetic and deployable structures\, because of the following re
 asons.\n\n1. The structure based on a watertight surface is suitable for c
 onstructing an envelope of a space\, a roof\, or a facade.\n2. Purely geom
 etric mechanism that does not rely on the elasticity of materials can real
 ize robust kinetic structure in a larger scale under gravity.\n3. The conf
 iguration is controlled by a few degrees of freedom. This enables a semi-a
 utomatic deployment of the structure.\n\nSince rigid origami transforms in
  a rigorous synchronized motion based on multiple non-linear constraints\,
  the design of rigid origami is not a trivial problem given by an arbitrar
 y design approach without geometric considerations (e.g.\, copy and paste 
 of origami patterns).\nIn this talk\, the speaker introduces his researche
 s on computational methods to design and solve rigid origami structures.\n
 Some of the design systems (Rigid Origami Simulator and Freeform Origami) 
 are available in the speaker's webpage (http://www.tsg.ne.jp/TT/software/)
