WebThis subdivision has 4 vertices, 6 edges and 4 faces, so its Euler characteristic is. Figure 86. Similarly, the cube gives rise to a subdivision of the sphere . Figure 87. This subdivision has 8 vertices, 12 edges and 6 faces, so its Euler characteristic is. WebJun 21, 2013 · The total number of half-edges in the mesh is 2 E, since each edge has two halves; and it's also 3 F, since each face touches three half-edges and this counts all the half-edges exactly once. Therefore 2 E = 3 F. By solving for E or F and substituting into the formula V − E + F ≈ 0, we can easily derive your two facts:
