This work follows Stefan Gustavson's paper "Simplex noise demystified" http://www.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf without using uniform arrays or texture engines. The resulting noise functions are fast and self contained, and their performance scales well with massive parallelism. Simplex noise functions are (C) Ashima Arts Classic noise functions are (C) Stefan Gustavson Source code for the noise functions is released under the conditions of the MIT license.
