Construction of a 2D honeycomb. Each honeycomb edge (black) is perpendicular to a line (thin green) joining two neighboring generating points (green dots), equally spaced in two parallel rows on both sides of the mean honeycomb plane (dashed green line) passing through the centers of symmetry at mid-points of the bottom edges of each cell. The vertical edges are of arbitrary height, but they all reach the same level at the honeycomb outer base (where the openings of the cells are). |
