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);
