## What it is
FastNoise Lite is a highly portable noise generation library offering 2D/3D Perlin, OpenSimplex2, Cellular (Voronoi), Value, and Cubic noise with fractal options and domain warping. It is implemented in many languages (C#, C++, C, Java, JavaScript, Rust, Go, GLSL/HLSL, and more) with a focus on high performance and easy integration.

## Use cases
- generate procedural terrain heightmaps for a game
- create perlin or simplex noise textures in a shader
- generate seamless 2D and 3D noise for procedural content
- add fractal noise to a voxel world generator
- sample cellular voronoi noise for stylized visuals
- port consistent noise generation across multiple languages
- generate noise for texture synthesis and material design

## When to choose
- you need fast, lightweight noise generation with minimal dependencies
- you want the same noise output across many programming languages
- you need 2D/3D noise with fractals and domain warping out of the box
- you want a permissive MIT-licensed noise library that's easy to integrate

## When to avoid
- you need SIMD-optimized performance or complex node-graph noise configurations (use FastNoise2)
- you need 4D or higher-dimensional noise
- you need advanced features like erosion simulation or flow noise
