NAME

Math::Project3D::Function - Generate anonymous subroutines for use as functions with Math::Project3D

SYNOPSIS

use Math::Project3D;

# Looks like a screw
my $function = Math::Project3D->new_function(
  'u,v',     # list of parameter names
  '$u',      # first component
  'sin($v)', # more components
  'cos($v)',
);

# or as an anonymous sub / closure!
{
    # This is a sphere
    my $radius = 5;

    my $x_component = sub {
        my $theta = shift;
        my $phi   = shift;
        return $radius * sin($theta) * cos($phi);
    };
    my $y_component = sub {
        my $theta = shift;
        my $phi   = shift;
        return $radius * sin($theta) * sin($phi);
    };
    my $z_component = sub {
        my $theta = shift;
        return $radius * cos($theta);
    };
    
    $function = Math::Project3D->new_function(
      $x_component, $y_component, $z_component         
    );
}

DESCRIPTION

This package contains the code for generating anonymous subroutines for use as functions with the Math::Project3D module. The package has no public subroutines and you should use it indirectly through the new_function method of Math::Project3D.

Oh, yes, I almost forgot. Do not read the source. :-)

METHODS

Public methods

new

The new method takes exactly the same arguments as the new_function method of Math::Project3D.

It returns a new Math::Project3D::Function object.
