dc.description.abstract | We present a new algorithm to compute motorcycle graphs. It runs in O(n root n log n) time when n is the number of motorcycles. We give a new characterization of the straight skeleton of a nondegenerate polygon. For a polygon with n vertices and h holes, we show that it yields a randomized algorithm that reduces the straight skeleton computation to a motorcycle graph computation in expected O(n root n + 1 log(2) n) time. Combining these results, we can compute the straight skeleton of a nondegenerate polygon with h holes and with n vertices, among which r are reflex vertices, in O(n root n + 1 log(2) n + r root r log r) expected time. In particular, we can compute the straight skeleton of a nondegenerate polygon with n vertices in O(n root n log(2) n) expected time | - |
