NAME
Algorithm::Line::Lerp - 2D grid line drawing via linear interpolation
SYNOPSIS
use Algorithm::Line::Lerp 'line';
my $points = line( [0,0], [2,11] );
for my $p (@$points) { ...DESCRIPTION
This module uses linear interpolation to return a list of points forming a line between two points on a grid. See eg/bench for a comparison of a perl Bresenham, a perl lerp, and the line function of this module.
Caveats include potential floating point portability problems and "aesthetic issues" depending on how lround behaves.
FUNCTION
Not exported by default.
- line p1 p2
-
Given two points (array references of x, y values) returns an array reference of the points between the two points. This may simply be a copy of point p1 (when p1 and p2 are equal) or a longer list of points.
Magic is not supported.
