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

use <pixel/px_polyline.scad>;
use <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);
}

use <pixel/px_polyline.scad>;
use <sphere_spiral.scad>;

points_angles = sphere_spiral(
	radius = 20, 
	za_step = 5
);

points = [
	for(pa = points_angles) 
	let(pt = pa[0])
	[round(pt[0]), round(pt[1]), round(pt[2])]
];

for(a = [0:30:330]) { 
	rotate(a) 
		for(pt = px_polyline(points)) {
			translate(pt)
				cube(1, center = true);
		}
