hull_polyline2d

Creates a 2D polyline from a list of [x, y] coordinates. As the name says, it uses the built-in hull operation for each pair of points (created by the circle module). It's slow. However, it can be used to create metallic effects for a small $fn, large $fa or $fs.

Parameters

• points : The list of [x, y] points of the polyline. The points are indexed from 0 to n-1.
• width : The line width. Default to 1.
• $fa, $fs, $fn : Check the circle module for more details.

Examples

use <hull_polyline2d.scad>;

$fn = 4;

hull_polyline2d(
    points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], 
    width = 1
);
