|
|
|
|
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);
|
|
}
