vrn3_from

Create a 3D version of Voronoi diagram.

Since: 2.4

Parameters

• points : Points for each cell.
• spacing : Distance between cells. Default to 1.

Examples

use <voronoi/vrn3_from.scad>

r = 30;

zas = rands(0, 359, 12);
yas = rands(0, 179, 12);

points = [
    for(i = [0:len(zas) - 1])
    [
        r * cos(yas[i]) * cos(zas[i]), 
        r * cos(yas[i]) * sin(zas[i]), 
        r * sin(yas[i])
    ]
];

#for(pt = points) {
    translate(pt) cube(1);
}

intersection() {
    sphere(r);
    vrn3_from(points);
}

use <voronoi/vrn3_from.scad>

r = 30;
thickness = 2;

        r * sin(yas[i])
    ]
