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 = //Generate noise values on a gridforvar i=0; i<10; ++i forvar j=0; j<10; ++j console //Optimized methods are available for up to 4 dimensionsvar t = sn //You can also use floating point precision, which is slightly fastervar s = sn
API
var sn =
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.
