SYNOPSIS

 use Math::Polygon::Convex  qw/chainHull_2D/;

 my @points = ( [1,2], [2,4], [5,7], [1,2] );
 my $poly   = chainHull_2D @points;

DESCRIPTION

The "convex polygon" around a set of points, is the polygon with a minimal size which contains all points.

This package contains one convex calculation algorithm, but may be extended with alternative implementations in the future.
