- Direct Known Subclasses:
SimpleEdgeSetIntersector
,SimpleMCSweepLineIntersector
,SimpleSweepLineIntersector
An EdgeSetIntersector computes all the intersections between the
edges in the set. It adds the computed intersections to each edge
they are found on. It may be used in two scenarios:
- determining the internal intersections between a single set of edges
- determining the mutual intersections between two different sets of edges
SegmentIntersector
to compute the intersections between
segments and to record statistics about what kinds of intersections were found.- Version:

computeIntersections
public abstract void computeIntersections(List edges, SegmentIntersector si, boolean testAllSegments) Computes all self-intersections between edges in a set of edges, allowing client to choose whether self-intersections are computed.- Parameters:
edges
- a list of edges to test for intersectionssi
- the SegmentIntersector to usetestAllSegments
- true if self-intersections are to be tested as well
-
computeIntersections
Computes all mutual intersections between two sets of edges.
