Class SimpleSweepLineIntersector

public class SimpleSweepLineIntersector
extends EdgeSetIntersector
Finds all intersections in one or two sets of edges, using a simple x-axis sweepline algorithm. While still O(n^2) in the worst case, this algorithm drastically improves the average-case time.
Version:
1.7

SimpleSweepLineIntersector()

Method Summary

void
computeIntersections(List edges0, List edges1, SegmentIntersector si)
