NoiseGo

Implementation of Improved Perlin Noise in Golang.

NoiseGo is written only around 100 lines of Go (in version : 1.0.1).

Usage

import(
    noise "github.com/TadaTeruki/NoiseGo/Noise"
)

func main(){
//  noise.New(seed int64, maxValue uint64) noise.Noise             
//   - Initialize noise generator                     
//  < arguments >                                     
//      seed : Seed value of noise            
//      maxValue : Maximum coordinate value (NOT float64)
//                 -When you queried a noise value with coodinate
//                  which is greater than maxValue or less than 0.0,
//                  the return value will be looped (See below comparison).
    nz := noise.New(100, 256)
    
    
// noise.Get(x, y float64) float64
//  - Get noise value with coordinate(x, y)
    r1 := nz.Get(200.2, 81.4)
    
// noise.GetOctaved(x, y float64, octaves int, persistence float64) float64
//  - Get octaved noise value with coordinate(x, y) and parameters(octaves, persistence)
    r2 := nz.GetOctaved(200.2, 81.4, 10, 0.5)
 
}

maxValue = 30	maxValue = 3

Installation

All you need to do is run:

 $ go get -u github.com/TadaTeruki/NoiseGo/Noise
