vrn2_space

Create a Voronoi diagram in the first quadrant. You specify a space and a grid width. The center of each cell will be distributed in each grid randomly.

Since: 2.4

Parameters

• size : 2 value array [x, y], rectangle with dimensions x and y.
• grid_w : The width of each grid. If it can split size equally, the voronoi diagram is seamless at the junction of top-bottom and left-right.
• seed : Seed value for random number generator for repeatable results.
• spacing : Distance between cells. Default to 1.
• r, delta, chamfer : The outlines of each cell can be moved outward or inward. These parameters have the same effect as offset.
• region_type : The initial shape for each cell can be "square" or "circle". Default to "square".

Examples

use <voronoi/vrn2_space.scad>;

vrn2_space(
    size = [40, 20],
    grid_w = 5
);

use <bend_extrude.scad>;
use <voronoi/vrn2_space.scad>;

size = [60, 20];

bend_extrude(size = size, thickness = 1, angle = 360) 
    difference() {
        square(size);
        vrn2_space(
            size = size,
            grid_w = 5,
            seed = 1
        );
    }
