NAME
Geometry::Primitive::Arc
DESCRIPTION
Geometry::Primitive::Arc represents a closed segment of a curve.
SYNOPSIS
use Geometry::Primitive::Arc;
my $arc = Geometry::Primitive::Arc->new(
angle_start => 0,
angle_end => 1.57079633,
radius => 15
);METHODS
Constructor
- new
-
Creates a new Geometry::Primitive::Arc
Instance Methods
