Math::PlanePath::Base::NSEW3pm

Usage

 package Math::PlanePath::Foo;
 use Math::PlanePath;
 use Math::PlanePath::Base::NSEW;
 @ISA = ('Math::PlanePath::Base::NSEW', 'Math::PlanePath');

Overview

This is a multi-inheritance mixin for paths which take only steps North, South, East and West by distance 1 each time. This includes for example the "SquareSpiral" and also things like the "DragonCurve" or "CCurve".

The following path descriptive methods are provided

                        value
    dx_minimum()         -1
    dx_maximum()          1
    dy_minimum()         -1
    dy_maximum()          1
    dsumxy_minimum()     -1
    dsumxy_maximum()      1
    ddiffxy_minimum()    -1
    ddiffxy_maximum()     1
    dir_maximum_dxdy()   0,-1    # maximum South
