And fixups: - Add missing bindings in RenderingServer - Remove duplicate ArrayMesh enum bindings (they're in Mesh already) - Remove redundant _unhandled_key_input binding in Control (it's in Node already)

This resource allows you to configure and sample a fractal noise space. Here is a brief usage example that configures an OpenSimplexNoise and gets samples at various positions and dimensions:
|
||
[codeblock]
|
||
var noise = OpenSimplexNoise.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))

Difference in period between [member octaves].

|
||
<member name="octaves" type="int" setter="set_octaves" getter="get_octaves" default="3">
|
||
Number of OpenSimplex noise layers that are sampled to get the fractal noise. Higher values result in more detailed noise but take more time to generate.
|

[b]Note:[/b] The maximum allowed value is 9.
|

</member>
|

<member name="period" type="float" setter="set_period" getter="get_period" default="64.0">
|
||
Period of the base octave. A lower period results in a higher-frequency noise (more value changes across the same distance).

</member>
|
||
<member name="persistence" type="float" setter="set_persistence" getter="get_persistence" default="0.5">
|
||
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.

|

<member name="seed" type="int" setter="set_seed" getter="get_seed" default="0">
|
||
Seed used to generate random values, different seeds will generate different noise maps.
