Two different cubic models with face-to-face-distance L. (a) Cube with truncated edges. All 12 edges are truncated by sectional planes. Each sectional plane (an example is marked in blue) is defined by a support vector a and a normal vector n which stands perpendicular to the plane. (b) Cube with implied rounded edges. The curve of each edge is defined by identical cylinders with curvature radius Rcurve which touch the associated cubic sides. |
