| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recent research on graph drawing focuses on Right-Angle-Crossing (RAC) drawings of 1-plane graphs, where each edge is drawn as a straight line and two crossing edges only intersect at right angles. We give a transformation from a restricted case of the RAC drawing problem to a problem of finding a straight-line drawing of a maximal plane graph where some angles are required to be acute. For a restricted version of the latter problem, we show necessary and sufficient conditions for such a drawing to exist, and design an $O(n^2)$-time algorithm that given an $n$-vertex plane graph produces a desired drawing of the graph or reports that none exists. | |
