Figure 4
Schlegel diagram of a facetted cube. This representation of polyhedral topology can help to assign vertex indices in a systematic way, which then facilitates the coding of
C and
T. The topology array
T has elements (0, 1, 2, 3, 4, 5, 6, 7), (0, 8, 1) etc. The coordinate array
C, parameterized on lengths a and b, has elements (a, b, a), (b, a, a), (−b, a, a) etc. |
