# GKVoronoiNoiseSource A procedural noise generator whose output (also called Worley noise or cellular noise) divides space into discrete cells surrounding random seed points. ``` class GKVoronoiNoiseSource ``` ## Overview Voronoi noise can generate textures resembling natural phenomena such as crystalline structures, cracked mud, or star fields.  Like all [`GKNoiseSource`](/documentation/GameplayKit/GKNoiseSource) subclasses, a Voronoi noise source represents a noise generation algorithm and its parameters. To make use of a noise source, first create [`GKNoise`](/documentation/GameplayKit/GKNoise) object from it (and optionally apply operations to that noise object or combine it with other noise objects). Then create a [`GKNoiseMap`](/documentation/GameplayKit/GKNoiseMap) object from your noise object, generating a concrete field of values that you can sample from directly or visualize using the or `SKTileMap` class. ## Topics ### Creating a Noise Source [`init(frequency:displacement:distanceEnabled:seed:)`](/documentation/GameplayKit/GKVoronoiNoiseSource/init(frequency:displacement:distanceEnabled:seed:)) Initializes a Voronoi noise source with the specified parameters. [`voronoiNoise(withFrequency:displacement:distanceEnabled:seed:)`](/documentation/GameplayKit/GKVoronoiNoiseSource/voronoiNoise(withFrequency:displacement:distanceEnabled:seed:)) Creates a Voronoi noise source with the specified parameters. ### Managing Noise Generation Parameters [`frequency`](/documentation/GameplayKit/GKVoronoiNoiseSource/frequency) A value that determines the number and size of cells in generated noise. [`displacement`](/documentation/GameplayKit/GKVoronoiNoiseSource/displacement) The range of random values to assign to each cell in generated noise. [`isDistanceEnabled`](/documentation/GameplayKit/GKVoronoiNoiseSource/isDistanceEnabled) A Boolean value that specifies whether generated noise values incorporate the distance from each point to the nearest seed point. [`seed`](/documentation/GameplayKit/GKVoronoiNoiseSource/seed) The value that determines the specific configuration of noise produced by the noise source. --- Copyright © 2026 Apple Inc.
