Noise generator based on Open Simplex.
This resource allows you to configure and sample a fractal noise space.
Here is a brief usage example that configures a SimplexNoise and gets samples at various positions and dimensions:
[codeblock]
var noise = SimplexNoise.new()
# Configure
noise.seed = randi()
noise.octaves = 4
noise.period = 20.0
noise.persistance = 0.8
#Sample
print("Values:")
print(noise.get_noise_2d(1.0,1.0))
print(noise.get_noise_3d(0.5,3.0,15.0))
print(noise.get_noise_3d(0.5,1.9,4.7,0.0))
[/codeblock]
Generate a noise image with the requested [code]width[/code] and [code]height[/code], based on the current noise parameters.
2D noise value [-1,1] at position [code]x[/code],[code]y[/code].
2D noise value [-1,1] at position [code]pos.x[/code],[code]pos.y[/code].
3D noise value [-1,1] at position [code]x[/code],[code]y[/code],[code]z[/code].
3D noise value [-1,1] at position [code]pos.x[/code],[code]pos.y[/code],[code]pos.z[/code].
4D noise value [-1,1] at position [code]x[/code],[code]y[/code],[code]z[/code],[code]w[/code].
Generate a tileable noise image, based on the current noise parameters.
Generated seamless images are always square ([code]size[/code]x[code]size[/code]).
Difference in period between [member octaves].
Number of Simplex Noise layers that are sampled to get the fractal noise.
Period of the base octave.
A lower period results in a higher frequancy noise (more value changes across the same distance).
Contribuiton factor of the different octaves.
A [code]persistance[/code] value of 1 means all the octaves have the same contribution, a value of 0.5 means each octave contributes half as much as the previous one.
Seed used to generate random values, different seeds will generate different noise maps.
