GKPerlinNoiseSource
A procedural noise generator whose output is a type of fractal coherent noise resembling natural phenomena such as clouds and terrain.
Declaration
class GKPerlinNoiseSourceOverview
Like all GKNoiseSource subclasses, a Perlin noise source represents a noise generation algorithm and its parameters. To make use of a noise source, first create 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.
