Plane sweep algorithms for intersecting geometric figures
O n log, n ).
The sweeping approach may be generalised to higher dimensions.
Foundations of Computer Science (focs '76),. .Article, bibliometrics, citation Count:.Generalizations and extensions edit Topological sweeping is a form of the plane sweep with a relaxed ordering of processing points, which avoids the necessity of completely sorting the points; it allows some sweep line algorithms h&r block military discount 2015 to be performed more efficiently.References edit Shamos, Michael.The rotating calipers technique for designing geometric algorithms may also be interpreted as a form of plane sweep, in the projective dual of the input plane: a form of projective duality transforms the slope of a line in one plane into the x -coordinate.Downloads (cumulative 2,015, downloads (12 Months 47, downloads (6 Weeks 6).Full Text: PDF, published in: Magazine, communications of the ACM, cACM Homepage archive.Pages 739-747, aCM, new York, NY, USA table of contents doi.1145/358656.N segments in the plane in time complexity.208215, doi :.1109/sfcs.1976.16.
In computational geometry, a sweep line algorithm or plane sweep algorithm is an algorithmic paradigm that uses a conceptual sweep line or sweep surface to solve various problems in, euclidean space.
2 Since then, this approach has been used to design efficient algorithms for a number of problems, such as construction of the Voronoi diagram ( Fortune's algorithm ) and the Delaunay triangulation or Boolean operations special cash sweep 13d past result on polygons.
Citation needed, applications edit, application of this approach led to a breakthrough in the computational complexity of geometric algorithms when, shamos and Hoey presented algorithms for line segment intersection in the plane, cheap golf irons canada and in particular, they described how a combination of the scanline approach with.
; Hoey, Dan (1976 "Geometric intersection problems Proc.This approach may be traced to scanline algorithms of rendering in computer graphics, followed by exploiting this approach in early algorithms of integrated circuit layout design, in which a geometric description of an IC was processed in parallel strips, because the entire description could not.1, the closely related BentleyOttmann algorithm uses a sweep line technique to report all K intersections among any N segments in the plane in time complexity of O( N K ) log N ) and space complexity of O( N ).Souvaine, Diane (2008 Line Segment Intersection Using a Sweep Line Algorithm (PDF).The idea behind algorithms of this type is to imagine that a line (often a vertical line) is swept or moved across the plane, stopping at some points.Volume 25 Issue 10, Oct 1982.Geometric operations are restricted to geometric objects that either intersect or are in the immediate vicinity of the sweep line whenever it stops, and the complete solution is available once the line has passed over all objects.It is one of the key techniques in computational geometry.Plane, sweep Algorithms for.Algorithms in computational geometry are of increas- ing importace in computer-aided design, for example.Plane - sweep algorithms for intersecting geometric figures, Published by ACM 1982 Article.Citation Count: 52 Downloads ( cumulative 2,003 Downloads (12 Months 53 Downloads (6 Weeks.
