O.3 A Sweep Line Algorithm To detect whether there’s an intersection in a set of more than just two segments, we use something called a sweep line algorithm. First let’s give each segment a unique label. I’ll use letters, but in a real...
This is my humble take on an implementation of the segment line intersection sweep-line algorithm. The library crate also contains aline intersection function. This crate is educational, not ready for any production purpose. It has been adopted as aglamandcgmathlibraryhere: Linestring. ...
Plane sweep paradigm is used for finding geometric intersection in an efficient manner. However, it is difficult to parallelize due to its in-order processing of spatial events. We present a new fine-grained parallel algorithm for geometric intersection and its CPU and GPU implementation using ...
Algorithm Steps Vertices are entered into a priority queue sorted from left to right An empty priority queue is created to store segments encountered An item is removed from the priority queue If the vertex is the left endpoint of a segment, we test it against every other segment in the segm...
First, C is approximated with a set of line segments. Then for a segment ((x1, y1), (x2, y2)), with d = (x2 − x1)2 + (y2 − y1)2, a scalar field can be defined: f (x, y) = 1 d ((x − x1)(y2 − y1) − (y − y1)(x2 − x1)) A circular ...

Line Segment Intersection Using a Sweep LineSouvaine, Diane
Historical Background The plane sweep algorithm, or sweep line algorithm, originated from line segment intersection problem in computational geometry field. The paper and thesis written by Michael Shamos in the middle of 1970 first addressed the computational geometry problems. Later the book[ 1 ] ...
