WebbBesides deriving quasi-optimal solutions to simplex range searching in the arithmetic model, we also look at circular and polygonal range searching on a random access machine. Given n points in E2 we derive a data structure of size log n) for counting how many points fall inside a query convex k-gon (for arbitrary values of k).

Optimal Partition Trees - University of Illinois Urbana-Champaign

WebbThis paper considers the following problem: Given a set G of n (possibly intersecting) line segments in the plane, preprocess it so that, given a query ray ρ emanating from a point p, one can quickly compute the intersection point Φ … WebbIn Chapter 2 the authors saw that geographic information systems often store a map in a number of separate layers, each layer represents a theme from the map, that is, a specific type of feature such as roads or cities, which makes it easy for the user to concentrate … rawhide imdb

Webboffs in approximate range searching. First, we introduce the range sketching problem. Next, we present a space-time tradeoff for smooth convex ranges, which general-ize spherical ranges. Finally, we show how to modify the previousdata structure to obtaina … Webb7 mars 2008 · Computational Geometry: Algorithms and Applications Mark de Berg, Otfried Cheong, Marc van Kreveld, Mark Overmars Springer Science & Business Media, Mar 7, 2008 - Computers - 386 pages 4 Reviews...
