Returns 2D Worley noise values `[cell_x, cell_y, noise]`

at (x, y) coordinates.

It divides the space into grids. The nucleus of each cell is randomly placed in a grid.

**Since:** 2.3

## Parameters

`points`

: A list of`[x, y]`

coordinates.`seed`

: The random seed. If it's ignored, a randomized value will be used.`grid_w`

: The grid width. Default to 10. Smaller`grid_w`

makes more cells.`dist`

: The noise value of each point is based on its distance to other cells. Different distance strategies make different noises. The`dist`

parameter accepts`"euclidean"`

,`"manhattan"`

,`"chebyshev"`

or`"border"`

.

## Examples

```
use <noise/nz_worley2s.scad>;
size = [100, 50];
grid_w = 10;
dist = "euclidean"; // [euclidean, manhattan, chebyshev, border]
seed = 51;
points = [
for(y = [0:size.y - 1], x = [0:size.x - 1])
[x, y]
];
cells = nz_worley2s(points, seed, grid_w, dist);
for(i = [0:len(cells) - 1]) {
h = norm([cells[i][0], cells[i][1]]) % 10;
color([h, h, h] / 10)
linear_extrude(h)
translate(points[i])
square(1);
}
