noice
A procedural noise generation library for rust - forked from noise-rs
use noise::{Fbm, NoiseFn};
let fbm = Fbm::new();
let val = fbm.get([42.0, 37.0, 2.0]);
API
Gradient Noise
Gradient noise produces a smooth, continuous value over space. It's achieved by dividing space into regions, and placing a random gradient at each vertex, then blending between those gradients.
Perlin noise
A very fast and reasonable quality gradient noise:
Perlin::new()
OpenSimplex noise
A slower but higher quality form of gradient noise:
OpenSimplex::new()
Value Noise
Value noise (sometimes mistaken with gradient noise) produces lower quality smooth noise. It exhibits pronounced grid artifacts, but can be slightly faster than gradient noise. Benchmarks show it's about 1.2–1.3× faster than Perlin noise.
Cell neighbours are blended using a weighted S-curve linear interpolation method. This removes any discontinuities across grid edges.
Value::new()
Fractional Brownian Motion
A way of combining multiple octaves of a noise function to create a richer and more varied output:
Fbm::new()
Worley Noise
Named after Steven Worley, and also called Voronoi noise, is based on dividing space into cells based on proximity to a random set of seed points.
Worley::new()
Noise Functions
These are the actual noise functions, which just take a coordinate using get()
and return
a value. They can be chained together when declared, creating very complex noise results.
See the individual function pages for their descriptions, and the examples for their usage.
