{"year":"2013","abstract":[{"lang":"eng","text":"A straight skeleton is a well-known geometric structure, and several algorithms exist to construct the straight skeleton for a given polygon or planar straight-line graph. In this paper, we ask the reverse question: Given the straight skeleton (in form of a planar straight-line graph, with some rays to infinity), can we reconstruct a planar straight-line graph for which this was the straight skeleton? We show how to reduce this problem to the problem of finding a line that intersects a set of convex polygons. We can find these convex polygons and all such lines in \$O(nlog n)\$ time in the Real RAM computer model, where \$n\$ denotes the number of edges of the input graph. We also explain how our approach can be used for recognizing Voronoi diagrams of points, thereby completing a partial solution provided by Ash and Bolker in 1985.\r\n"}],"conference":{"location":"St. Petersburg, Russia","start_date":"2013-07-08","end_date":"2013-07-10","name":"ISVD: Voronoi Diagrams in Science and Engineering"},"language":[{"iso":"eng"}],"citation":{"mla":"Biedl, Therese, et al.
