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.persistence = 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_4d(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.
Returns the 2D noise value [code][-1,1][/code] at the given position.
Returns the 2D noise value [code][-1,1][/code] at the given position.
Returns the 3D noise value [code][-1,1][/code] at the given position.
Returns the 3D noise value [code][-1,1][/code] at the given position.
Returns the 4D noise value [code][-1,1][/code] at the given position.
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-frequency noise (more value changes across the same distance).
Contribution factor of the different octaves. A [code]persistence[/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.
