vx_polyline

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

Since: 2.4

Parameters

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

Examples

use <voxel/vx_polyline.scad>
use <shape_pentagram.scad>

pentagram = [
	for(pt = shape_pentagram(15)) 
		[round(pt.x), round(pt.y)]
];

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

use <voxel/vx_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.x), round(pt.y), round(pt.z)]
];

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