Geometric modeling method of hexagon mesh single-layer latticed shell
The invention discloses a geometric modeling method of a hexagon mesh single-layer latticed shell. The method comprises the steps that (1) a latticed shell vertex center regular hexagon mesh is established; (2) a second circle of six hexagon meshes are established; (3) an outer circle of hexagon meshes are established in sequence until the needed mesh number is reached; and (4) a plane parallel to the latticed shell vertex center regular hexagon mesh is used for intercepting the meshes, and needed latticed shell geometry is obtained. The established hexagon mesh single-layer latticed shell has the advantages that a whole curve surface formed by latticed shell joint points is smooth and close to a sphere face; the hexagon meshes are all placed in the same plane, and glass or roofs of other materials can be arranged conveniently; all joint points are only connected with three rod pieces, included angles between adjacent rod pieces are approximately the same, and accordingly latticed shell manufacturing and mounting are convenient; and except for latticed shell edge rod pieces, the other rod pieces of the latticed shell are the same in length, building effect is in order, and machining and manufacturing are convenient.
