Perlin noise generator implemented in Swift
This project is a based on a port of the CZGPerlinGenerator class as implemented in the perlin-iOS project.
It contains a demo app for experimenting with the PerlinGenerator parameters.
As of XCode 6.4 and an aging iPhone 4s, there is a noticable difference in performance between release and debug builds. A release build runs approximately 4 times quicker.
The implementation of the PerlinGenerator in the master branch of this repository supports 4 dimensions, although only two are visualised in the demo app. I've implemented a 2D version of the noise generator in the feature-2d-only branch, it is much quicker and allows the demo app to update in real-time.
