# vrn2_space
|
|
|
|
Create a [Voronoi diagram](https://en.wikipedia.org/wiki/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`](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Transformations#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
|
|
);
|
|
}
