NAME

Geometry::Primitive::Polygon - Closed shape with an arbitrary number of points.

DESCRIPTION

Geometry::Primitive::Polygon represents a two dimensional figure bounded by a series of points that represent a closed path.

SYNOPSIS

   use Geometry::Primitive::Polygon;
 
   my $poly = Geometry::Primitive::Polygon->new;
   $poly->add_point($point1);
   $poly->add_point($point2);
   $poly->add_point($point3);
   # No need to close the path, it's handled automatically
