The SIMD typedef allows us to abstract the __m128 and __m256 types for each\ncase.  It should not be too hard to adapt this to AVX512 or other instruction sets, just add\na new set of #defines for the instructions in question, and a new typedef for SIMD. Please \nfeel free to add other SIMD platforms and pull request!\n\nFastNoise3d.h / cpp\n-------------------\nThe base Perlin and Simplex noise functions, provided in both SIMD and non SIMD form.\n \n\nFractalNoise3d.h / cpp\n----------------------\nVarious fractal noise variants, in SIMD and non SIMD form.These methods iterate overthe noise \nfunctions at different scales, providing very detailed and interesting patterns.\n\n\nNoiseUtility.h / cpp\n--------------------\nUtility functions to grab large chunks of noise at a time. The Sphere methods will create noise\nthat can be texture mapped to a sphere. Methods to return 2d noise for flat textures and methods\nthat accept a set of coordinates and return the noise would be next up. Feel free to pull request that!\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjackmott%2Ffastnoise-simd","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjackmott%2Ffastnoise-simd","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjackmott%2Ffastnoise-simd/lists"}
