# midpt_smooth
|
|
|
|
Given a 2D path, this function constructs a mid-point smoothed version by joining the mid-points of the lines of the path.
|
|
|
|
**Since:** 1.3
|
|
|
|
## Parameters
|
|
|
|
- `points` : The path points.
|
|
- `n` : Perform mid-point smoothing n times.
|
|
- `closed` : Is the points a 2D shape? If it's `true`, the function takes the last point and the first one to calculate a middle point. Default to `false`.
|
|
|
|
## Examples
|
|
|
|
use <polyline_join.scad>
|
|
use <shape_taiwan.scad>
|
|
use <midpt_smooth.scad>
|
|
|
|
taiwan = shape_taiwan(50);
|
|
smoothed = midpt_smooth(taiwan, 20, true);
|
|
|
|
translate([0, 0, 0])
|
|
polyline_join(taiwan)
|
|
circle(.125);
|
|
|
|
#translate([10, 0, 0])
|
|
polyline_join(smoothed)
|
|
circle(.125);
