# bezier_curve
Given a set of control points, the `bezier_curve` function returns points of the Bézier path.
## Parameters
- `t_step` : 0 ~ 1. Control the distance between two points of the Bézier path.
- `points` : A list of `[x, y]` or `[x, y, z]` control points.
## Examples
If you have four control points:
use <polyline_join.scad>
use <bezier_curve.scad>
t_step = 0.05;
radius = 2;
p0 = [0, 0, 0];
p1 = [40, 60, 35];
p2 = [-50, 90, 0];
p3 = [0, 200, -35];
points = bezier_curve(t_step,
[p0, p1, p2, p3]
);
polyline_join(points)
sphere(radius);
