Given a 2D path, this function constructs a mid-point smoothed version by joining the mid-points of the lines of the path.
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
use <hull_polyline2d.scad>; use <shape_taiwan.scad>; use <midpt_smooth.scad>; taiwan = shape_taiwan(50); smoothed = midpt_smooth(taiwan, 20, true); translate([0, 0, 0]) hull_polyline2d(taiwan, .25); #translate([10, 0, 0]) hull_polyline2d(smoothed, .25);
