# 2D Intersection of Curves

*Reference Manual*

*Baruch Zukerman and Ron Wein*

This chapter describes three functions implemented using the
sweep-line algorithm: given a collection $$ of
planar curves, compute all intersection points among them,
obtain the set of maximal pairwise interior-disjoint subcurves
of the curves in $$, or check whether there is at
least one pair of curves in $$ that intersect in
their interior.

The first two operations are performed in an output-sensitive
manner.
