# FastNoise SIMD
A mostly safe wrapper for [fastnoise-simd-bindings](https://crates.io/crates/fastnoise-simd-bindings) which is bindings for [FastNoiseSIMD](https://github.com/Auburns/FastNoiseSIMD).
FastNoise SIMD is the SIMD implementation of my noise library [FastNoise](https://github.com/Auburns/FastNoise). It aims to provide faster performance through the use of intrinsic(SIMD) CPU functions. Vectorization of the code allows noise functions to process data in sets of 4/8/16 increasing performance by 700% in some cases (Simplex).
After releasing FastNoise I got in contact with the author of [FastNoise SIMD](https://github.com/jackmott/FastNoise-SIMD) (naming is coincidence) and was inspired to work with SIMD functions myself. Through his code and discussions with him I created my implementation with even more optimization thanks to the removal of lookup tables.
Runtime detection of highest supported instruction set ensures the fastest possible performance with only 1 compile needed. If no support is found it will fallback to standard types (float/int).
