WIP successor to FastNoiseSIMD
Modular node based noise generation library 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
Bindings:
Roadmap:
The FastNoise2 noise tool provides a node graph editor to create trees of FastNoise2 nodes. Node trees can be exported as serialised strings and loaded into the FastNoise2 library in your own code. The noise tool has 2D and 3D previews for the node graph output, see screenshots below for examples.
Check the Releases for compiled NoiseTool binaries
FastNoise2 has continuous benchmarking to track of performance for each node type across commits
