# FastNoise2.jl
A Julia wrapper for [Auburn/FastNoise2](https://github.com/Auburn/FastNoise2) through the C API.
## Interactive Example
[](./notebooks/notebook.jl)
## Usage
```julia
julia> using FastNoise2
julia> n = Node("OpenSimplex2") # Create a node. List all the supported names with `keys(FastNoise2.NODE_NAMES_TO_ID)`
Node(Ptr{Nothing} @0x0000000002fa72b0, 1946463812)
julia> n(4, 3) # Generate one single noise value at specific 2D position
-0.4346525f0
julia> n(0.4,0.3,0.2) # 3D
0.5271185f0
julia> n(0.4,0.3,0.2,0.1) # 4D
0.5271185f0
julia> n((4,4), 4, 3) # Generate a 2D Matrix
