NAME

       Math::Polygon::Convex - Collection of convex algorithms

INHERITANCE

	Math::Polygon::Convex
	  is a Exporter

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.

FUNCTIONS

       chainHull_2D(POINTS)
	   Each POINT is an ARRAY of two elements: the X and Y coordinate of a point.  Returned is the enclosing convex Math::Polygon object.
