NAME

Vector::Object3D::Point::Cast - Three-dimensional point object casting into two-dimensional surface areas

SYNOPSIS

package Vector::Object3D::Point;

use Moose;
with 'Vector::Object3D::Point::Cast';

# Calling any method from this role requires providing an object of a base class
# and results in creation of a new instance of the same class:
my $point = Vector::Object3D::Point->new(coord => [-2, 3, 1]);

# Project point onto a two-dimensional plane using an orthographic projection:
my $point2D = $point->cast(type => 'parallel');

# Project point onto a two-dimensional plane using a perspective projection:
my $distance = 5;
my $point2D = $point->cast(type => 'perspective', distance => $distance);

DESCRIPTION

Vector::Object3D::Point::Cast is a Moose role that is meant to be applied to Vector::Object3D::Point class in order to provide it with additional methods of mapping three-dimensional points to a two-dimensional plane.

METHODS

cast

Project point onto a two-dimensional plane using an orthographic projection:

my $point2D = $point->cast(type => 'parallel');

Project point onto a two-dimensional plane using a perspective projection:

my $distance = 5;
my $point2D = $point->cast(type => 'perspective', distance => $distance);

BUGS

There are no known bugs at the moment. Please report any bugs or feature requests.

EXPORT

Vector::Object3D::Point::Cast exports nothing neither by default nor explicitly.
