vrn2_cells_space


Create cell shapes of Voronoi 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.

Examples

use <hull_polyline2d.scad>;
use <voronoi/vrn2_cells_space.scad>;

size = [20, 20];
grid_w = 5;
cells = vrn2_cells_space(size, grid_w);

for(cell = cells) {
    cell_pt = cell[0];
    cell_poly = cell[1];

    linear_extrude(1)
        hull_polyline2d(concat(cell_poly, [cell_poly[0]]), width = 1);

    color(rands(0, 1, 3))
    translate(cell_pt)    
    linear_extrude(2, scale = 0.8)
    translate(-cell_pt)    
        polygon(cell_poly);  
}
