vx_contour


Given a list of points that form a closed area, vx_contour returns the contour which encircles the area.

Since: 2.5

Parameters

  • points : A list of [x, y] points.
  • sorted : Default to false. If your points is sorted by x y, setting it to true will accelerate the calculation speed.

Examples

use <voxel/vx_ascii.scad>;
use <voxel/vx_contour.scad>;

t = "dotSCAD";

color("white")
linear_extrude(2)
for(i = [0:len(t) - 1]) {
    translate([i * 8, 0]) 
        for(pt = vx_ascii(t[i])) {
            translate(pt)
                square(1, center = true);
        }
}

color("black")
linear_extrude(1)
for(i = [0:len(t) - 1]) {
    translate([i * 8, 0]) 
        polygon(vx_contour(vx_ascii(t[i])));
}
