A Voronoi noise source generates a field of noise values by randomly picking seed points at random positions in a space, then dividing the space into cells so that all the points in a cell are closer to that cell’s seed point than to any other seed point.
After dividing space into cells, the noise source randomly assigns a unique value to each. If this property’s value is
false (the default), all points within a cell have the same value, creating a crystalline appearance. If this property’s value is
true, the noise source adds to each point’s value the distance from that point to the nearest seed point. With a low value for the
displacement property, adding distance to noise can create textures like cracked mud; with a high displacement value, adding distance creates textures like bubbling liquid.
