- public class MonotoneChainIndexer
- extends java.lang.Object
MonotoneChains are a way of partitioning the segments of an edge to
allow for fast searching of intersections.
They have the following properties:
Property 1 means that there is no need to test pairs of segments from within
the same monotone chain for intersection.
Property 2 allows
binary search to be used to find the intersection points of two monotone chains.
For many types of real-world data, these properties eliminate a large number of
segment comparisons, producing substantial speed gains.
- the segments within a monotone chain will never intersect each other
- the envelope of any contiguous subset of the segments in a monotone chain
is simply the envelope of the endpoints of the subset.
