This library is a D implementation of OpenSimplex2, a public-domain noise algorithm similar to Perlin noise and Simplex noise. Like the algorithm itself, this library is released into the public domain.
I am not the author of the OpenSimplex2 algorithm, I just ported it to D (which involved barely more than a copy-paste of the Java code). I have no idea what most of the code does 😀 But it compiles and apparently produces the expected output so that's good!
The algorithm itself was created by KdotJPG.
Version 1.0.0 is a direct port of the Java code, but I would like to add an interface that's more idiomatic in the D world, perhaps more in line with std.random.
