On the Three-Dimensional Orthogonal Drawing of Outerplanar Graphs (Extended Abstract)

摘要

It has been known that every series-parallel 6-graph has a 2-bend 3-D orthogonal drawing, while it has been open whether every series-parallel 6-graph has a 1-bend 3-D orthogonal drawing. We show in this paper that every outerplanar 5-graph has a 1-bend 3-D orthogonal drawing.
