nz_perlin3

Returns the 3D Perlin noise value at the (x, y, z) coordinate.

Since: 2.3

Parameters

• x : The x coordinate.
• y : The y coordinate.
• z : The z coordinate.
• seed : The random seed.

Examples

use <util/rand.scad>
use <noise/nz_perlin3.scad>

seed = rand(0, 255);
noised = [
    for(z = [0:.2:5], y = [0:.2:5], x = [0:.2:5])
    [x, y, z, nz_perlin3(x, y, z, seed)]
];    

for(nz = noised) {
    if(nz[3] > 0.2) {
        translate([nz.x, nz.y, nz.z])
            cube(.2);
    }
}
