voronoiNoise(withFrequency:displacement:distanceEnabled:seed:)
Creates a Voronoi noise source with the specified parameters.
Declaration
class func voronoiNoise(withFrequency frequency: Double, displacement: Double, distanceEnabled: Bool, seed: Int32) -> SelfParameters
- frequency:
The initial value for the Frequency property, which determines the number and spacing of cells in generated noise.
- displacement:
The initial value for the Displacement property, which determines the variety of noise values between cells in generated noise.
- distanceEnabled:
The initial value for the Isdistanceenabled property, which determines whether to add distance values to generated noise.
- seed:
The initial value for the Seed property, which determines the overall structure of generated noise.
Return Value
A new noise source.
Discussion
To make use of this noise source, create a GKNoise object from it (and optionally apply operations to that noise object or combine it with other noise objects). Then create a GKNoiseMap object from your noise object, generating a concrete field of values that you can sample from directly or visualize using the SKTexture or SKTileMap class.
