1Bend 3D Orthogonal BoxDrawings: Two Open Problems Solved

... 49 · 2−26 dn2 , which gives the result ✷ Conclusion and open problems This paper solved two open problems regarding three-dimensional orthogonal 1-bend drawings, namely, that any 1-bend drawing ... [BTW01] for lower bounds for orthogonal graph drawing They have the useful property that for any two disjoint subsets of size Ω(n), there are Ω(m) edges between the two subsets...
