Given a set of control points, the `bezier_curve` function returns points of the Bézier path.
2017-03-22 10:47:09 +08:00
## Parameters
- `t_step` : The distance between two points of the Bézier path.
2019-07-28 18:24:48 +08:00
- `points` : A list of `[x, y]` or `[x, y, z]` control points.

## Examples

If you have four control points:

2021-12-04 10:57:29 +08:00
use <polyline_join.scad>;

use <bezier_curve.scad>;

t_step = 0.05;
2021-12-04 10:57:29 +08:00
radius = 2;
2017-03-22 10:47:09 +08:00
p0 = [0, 0, 0];
p1 = [40, 60, 35];
p2 = [-50, 90, 0];
p3 = [0, 200, -35];
2017-04-08 06:48:36 +08:00
points = bezier_curve(t_step,
2017-03-22 10:47:09 +08:00
[p0, p1, p2, p3]
);
2021-12-04 10:57:29 +08:00
