FastNoise Lite is an extremely portable open source noise generation library with a large selection of noise algorithms. This library focuses on high performance while avoiding platform/language specific features, allowing for easy ports to as many possible languages.
This project is an evolution of the original FastNoise library and shares the same goal: An easy to use library that can quickly be integrated into a project and provides performant modern noise generation. See a breakdown of changes from the transition to FastNoise Lite here
If you are looking for a more extensive noise generation library consider using FastNoise2. It provides large performance gains thanks to SIMD and uses a node graph structure to allow complex noise configurations with lots of flexibility.
- 2D & 3D sampling
- OpenSimplex2 noise
- OpenSimplex2S noise
- Cellular (Voronoi) noise
- Perlin noise
- Value noise
- Value Cubic noise
- OpenSimplex2-based domain warp
- Basic Grid Gradient domain warp
- Multiple fractal options for all of the above
- Supports floats and/or doubles

A compact testing application is available for testing all features included in FastNoise Lite with a visual representation. This can be used for development purposes, testing noise settings and generating noise textures for export.
Source code can be found in the WebPreviewApp directory.
