init(frequency:)
Initializes a sphere noise source with the specified frequency.
Declaration
init(frequency: Double)Parameters
- frequency:
The initial value for the Frequency property, which determines the size and spacing of concentric spheres.
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.
