In pathmapping: Compute Deviation and Correspondence Between Spatial Paths

Description

Checks whether two line segments intersect.

Usage

linesIntersect(A1, A2, B1, B2)

Arguments

A1	one end of line A (x,y) pair
A2	other end of line A (x,y) pair
B1	one end of line B (x,y) pair
B2	other end of line B (x,y) pair
