Module Version: 1.02
Math::Polygon::Convex - Collection of convex algorithms

Math::Polygon::Convex is a Exporter

use Math::Polygon::Convex qw/chainHull_2D/; my @points = ( [1,2], [2,4], [5,7], [1,2] ); my $poly = chainHull_2D @points;

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.

**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.
