px_polyline


Given a list of points. px_polyline returns points that can be used to draw a pixel-style polyline.

Since: 2.0

Parameters

  • points : A list of points. Each point can be [x, y] or [x, y, z]. x, y, z must be integer.

Examples

include <pixel/px_line.scad>;
include <pixel/px_polyline.scad>;
include <shape_pentagram.scad>;

pentagram = [
    for(pt = shape_pentagram(15)) 
        [round(pt[0]), round(pt[1])]
];

for(pt = px_polyline(concat(pentagram, [pentagram[0]]))) {
    translate(pt) 
        linear_extrude(1, scale = 0.5) 
            square(1, center = true);
}
