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