vrn2_cells_from

Creats Voronoi shapes from a list of points.

Since: 2.4

Parameters

• points : Points for each cell.

Examples

use <hull_polyline2d.scad>;
use <voronoi/vrn2_cells_from.scad>;

xs1 = rands(-20, 20, 15);
ys1 = rands(-20, 20, 15);
points = [for(i = [0:len(xs1) - 1]) [xs1[i], ys1[i]]];

cells = vrn2_cells_from(points);
for(i = [0:len(points) - 1]) {
    pt = points[i];
    cell = cells[i];
    
    linear_extrude(1)
        hull_polyline2d(concat(cell, [cell[0]]), width = 1);
    
    color(rands(0, 1, 3))
    translate(pt)    
    linear_extrude(2, scale = 0.8)
    translate(-pt)    
        polygon(cell);
