# Packages
Package chain Define Monotone Chains,it is a way of partitioning the segments of a linestring to allow for fast searching of intersections.
Package snap Snaps the vertices and segments of a Geometry's vertices to another Geometry's vertices.
Package sweepline Contains struct which implement a sweepline algorithm for scanning geometric data structures.
# Functions
AddPointToVertexSlice add point to vertex slice.
Difference returns a geometry that represents that part of geometry A that does not intersect with geometry B.
Intersection Computes the Intersection of two geometries,either or both of which may be null.
IntersectLine returns a array that represents that part of geometry A intersect with geometry B.
LineMerge returns a Geometry containing the LineMerges.
MergeLine Computes the Merge of two geometries.
MergeMatrix Computes the Merge of two geometries,either or both of which may be matrix.
