FastNoise2

WIP successor to FastNoiseSIMD

Modular node based noise generation using SIMD, modern C++17 and templates

FastNoise2 is a fully featured noise generation library which aims to meet all your coherent noise needs while being extremely fast

Uses FastSIMD to compile classes with multiple SIMD types and selects the fastest supported SIMD level at runtime - Scalar (non-SIMD) - SSE2 - SSE4.1 - AVX2 - AVX512

Supports: - 32/64 bit - Windows - Linux - MacOS - MSVC - Clang - GCC

Check the releases for early versions of the Noise Tool
