# noise methods
The following methods are all part of the **noise methods**\.
Defines 2D, 3D and 4D procedural noise functions Based on the work of Stefan Gustavson and Ashima Arts on "webgl\-noise": https://github.com/ashima/webgl-noise Following Stefan Gustavson's paper "Simplex noise demystified": http://www.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf
