Jan 1, 2019 · Our method works not only for points on a terrain, but it works for points on any polyhedral surface in \BbbR 3 that is a topological disk. The ...
Let S be a set of n points on a polyhedral terrain T in R 3 , and let ε > 0 be a fixed constant. We prove that S admits a ( 2 + ε ) -spanner with O ( n log ...
(Kapoor and Li [10] studied geodesic spanners on polyhderal surfaces, but their spanner construction uses Steiner points and its size depends on the so ...
We prove that S admits a (2 + ∊)-spanner with O(n log n) edges with respect to the geodesic distance. This is the first spanner with constant spanning ratio and ...
