# bezier_smooth
|
|
|
|
Given a path, the `bezier_smooth` function uses bazier curves to smooth all corners. You can use it to create smooth lines or rounded shapes.
|
|
|
|
## Parameters
|
|
|
|
- `path_pts` : A list of points represent the path.
|
|
- `round_d` : Used to create the other two control points at the corner.
|
|
- `t_step` : The distance between two points of the Bézier path at the corner. It defaults to 0.1.
|
|
- `closed` : It defaults to `false`. If you have a closed path, set it to `true`.
|
|
- `angle_threshold` : Default to 0. If the angle between two line segments is bigger than `angle_threshold`, smooth those two segments. **Since:** 3.0
|

## Examples
|
|
|
|
use <polyline_join.scad>
|
|
use <bezier_smooth.scad>
|
|
|
|
width = 2;
|
|
round_d = 15;
|
|
|
|
path_pts = [
|
|
[0, 0, 0],
|
|
[40, 60, 10],
|
|
[-50, 90, 30],
|
|
[-10, -10, 50]
|
|
];
|
|
|
|
polyline_join(path_pts)
|
|
sphere(width / 2);
|
|
|
|
smoothed_path_pts = bezier_smooth(path_pts, round_d);
|
|
|
|
color("red")
|
|
translate([30, 0, 0])
|
|
polyline_join(smoothed_path_pts)
|
|
sphere(width / 2);

|
|

|
|
];
|
