PROBLEM TO BE SOLVED: To provide a method of producing a foldable three-dimensional structure which produces an enclosed three-dimensional shape such as a spherical shape, elliptical shape, or spheroid shape easy to fold flat from the three-dimensional shape, and to provide the three-dimensional structure.SOLUTION: A method of producing a foldable three-dimensional structure, includes: setting an axis penetrating a three-dimensional model; defining two axis points in the vicinity of points of intersection of the three-dimensional model and the axis; defining n intermediate points between the two axis points; defining a pair of top planes passing through the axis points, respectively; defining n first planes passing through n intermediate points, respectively, and perpendicular to the axis; defining m second planes sharing the axis and not parallel to each other; defining a plurality of top planar points at or about the points of intersection of the top planes, second planes, and the three-dimensional model; defining a plurality of planar points at or about the points of intersection of the first planes, second planes, and the three dimensional model; connecting the top planar points on one top plane are connected to the top planar points on the other top plane through the planar points; and deciding the structural model. |
