    spatial-noise

    Spatially determinisitc n-dimensional noise generators. Useful for things like games, procedural generation and quick testing of numerical algorithms.

    Install

    npm install spatial-noise
    

    Example

    var sn = require("spatial-noise")
     
    //Generate noise values on a grid
    for(var i=0; i<10; ++i) {
      for(var j=0; j<10; ++j) {
        console.log(i, j, "->", sn(i, j))
      }
    }
     
    //Optimized methods are available for up to 4 dimensions
    var t = sn.noise4d(10.01, 0.5, 10.0, Date.now())
     
    //You can also use floating point precision, which is slightly faster
    var s = sn.noise2f(5, 6)

    API

    var sn = require("spatial-noise")

    Double Precision

    • sn.noise1d(x)
    • sn.noise2d(x,y)
    • sn.noise3d(x,y,z)
    • sn.noise4d(x,y,z,t)
    • sn.noiseNd( ... )

    Generates a spatially varying noise function in some fixed dimension taking doubles as arguments.

    Note require("spatial-noise") is an alias for sn.noiseNd( ... ) and takes a variable number of arguments.

    Float Precision

    • sn.noise1f(x)
    • sn.noise2f(x,y)
    • sn.noise3f(x,y,z)
    • sn.noise4f(x,y,z,t)
    • sn.noiseNf( ... )

    Same deal as above, except arguments are all 32 bit floats instead of 64 bit doubles.
