webgl-noise contain Simplex Noise functions that are fast and self contained, with performance that scales well with massive parallelism. While not quite as fast as Gustavson's original implementation on typical current desktop GPUs, they are more scalable to massive parallelism and much more convenient to use, and they can make good use of unused ALU resources when run concurrently with a typical texture-intensive rendering. Gustavson's implementation makes heavy use of a texture lookup table and is texture bandwidth limited.
This work follows Stefan Gustavson's paper "Simplex noise demystified" http://www.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf without using any uniform arrays or texture engines.
