FastNoise Lite is a noise generation package with a large selection of noise algorithms.
- 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
Here's an example for creating a 128x128 array of OpenSimplex2 noise
// Create and configure noise state (either float32 or float64)
var noise = fastnoise.New[float32]()
noise.NoiseType(fastnoise.OpenSimplex2)
// Gather noise data
var noiseData [128][128]float32
for x := 0; x < 128; x++ {
for y := 0; y < 128; y++ {
noiseData[x][y] = noise.Noise2D(x, y)
}
}
// Do something with this data...
