NAME

Math::PlanePath::MathImagePythagoreanUAD -- primitive pythagorean triples by U,A,D

SYNOPSIS

use Math::PlanePath::MathImagePythagoreanUAD;
my $path = Math::PlanePath::MathImagePythagoreanUAD->new;
my ($x, $y) = $path->n_to_xy (123);

DESCRIPTION

In progress.

FUNCTIONS

$path = Math::PlanePath::MathImagePythagoreanUAD->new ()

Create and return a new path object.

($x,$y) = $path->n_to_xy ($n)

Return the X,Y coordinates of point number $n on the path. Points begin at 0 and if $n < 0 then the return is an empty list.

Fractional positions give an X,Y position along a straight line between the integer positions. Integer positions are always just 1 apart either horizontally or vertically, so the effect is that the fraction part appears either added to or subtracted from X or Y.
