Ultra fast Perlin and Simplex noise functions sped up with SSE2,SSE4, and AVX2 instructions. If you are interested in this you may want to refer to: https://github.com/Auburns/FastNoiseSIMD A similarly named library inspired by this one that is more user friendly and even faster.
Contains SIMD constants, constant lookup tables, and SIMD intrinsic helper #defines which allow you to switch between SSE2, SSE4, and AVX2 builds by adjusting the #defines at the top. The SIMD typedef allows us to abstract the __m128 and __m256 types for each case. It should not be too hard to adapt this to AVX512 or other instruction sets, just add a new set of #defines for the instructions in question, and a new typedef for SIMD. Please feel free to add other SIMD platforms and pull request!
The base Perlin and Simplex noise functions, provided in both SIMD and non SIMD form.
Various fractal noise variants, in SIMD and non SIMD form.These methods iterate overthe noise functions at different scales, providing very detailed and interesting patterns.
Utility functions to grab large chunks of noise at a time. The Sphere methods will create noise that can be texture mapped to a sphere. Methods to return 2d noise for flat textures and methods that accept a set of coordinates and return the noise would be next up. Feel free to pull request that!
