Zusammenfassung: | A triangle element division method includes acquiring position information of a plurality of feature points positioned on a border of a two-dimensional planar figure, segmenting a virtual plane including the two-dimensional planar figure into a plurality of quadrangular cells, disposing additional points at positions where edges as line segments connecting two adjacent feature points on the border of the two-dimensional planar figure and borders of the plurality of cells cross, and vertices of the plurality of cells, for each of the plurality of cells, generating a plurality of triangle elements with the feature points and the additional points in the cell as vertices such that conditions that a region in the cell is filled with a plurality of the triangle elements and the triangle elements do not overlap each other are satisfied, and removing the triangle elements positioned outside the two-dimensional planar figure. |
