PROBLEM TO BE SOLVED: To provide a triangle mesh sewing method for sewing triangle meshes having a gap formed by curved poly-lines formed curved lines expressing the boundary of a triangle mesh, which is formed from a curved face of a three- dimensional model, and the curved face. SOLUTION: For each triangle mesh, a new triangle mesh and new boundary poly-lines are formed by eliminating a boundary triangle (S1), and when the new triangle mesh is in one of conditions of no phase change, boundary contact and boundary disappearance (S2: YES), for each of the apex the new boundary poly-lines and the curved poly-lines, a curved face parameter is calculated (S3), and a pair of the new boundary poly-lines and the curved poly-lines are formed from the state of the new triangle mesh and the curved face parameter value of each apex of the new curved poly-lines (S4), and a triangle mesh burying the gap between the poly-lines using a pair of this curved poly-lines, is formed and is added to the new triangle mesh (S5), for sewing the gap.
