Talk:OpenSimplex noise

Is the OpenSimplex Noise algorithm lacking a formal description? The article only links to a reference implementation by the author and a bit of searching doesn't reveal any description in the algorithm author's blog. The comments in the reference implementation are very detailed, so maybe that is the closest to a formal description this algorithm has? It would be useful, for example in deriving a gradient function in various dimensions, to have a formal mathematical description of the algorithm. Alex Kindel (talk) 21:30, 30 September 2017 (UTC)
