InsertIntersections: Inserts points on paths where two paths intersect

In pathmapping: Compute Deviation and Correspondence Between Spatial Paths

Description

This function does two rounds of insertion. First, it inserts a point on each path whenever path1 intersects path2. Next, it optionally inserts points on segments of one path that are 'opposite' points on the other path, to allow a monotonic mapping between the two paths.

Usage

InsertIntersections(path1, path2, insertopposites = T, verbose = F)

Arguments

path1	path1
path2	path2
insertopposites	T/F, whether points opposite points on the other path should be inserted
verbose	T/F, whether to print interim progress information

Value

A list of four data sequences are returned:

newpath1	New list 1 with new points inserted
newpath2	New list2 with new points inserted
key1	Set of indices mapping the points back to the original path 1. Inserted points are labeled -1
key2	Set of indices mapping the points back to the original path 2. Inserted points are labeled -1
