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