OpenSimplexNoise

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 an OpenSimplexNoise and gets samples at various positions and dimensions:

Functions

getImage Ref!Image getImage(long width, long height): Generate a noise image with the requested width and height, based on the current noise parameters.
getLacunarity double getLacunarity()
getNoise2d double getNoise2d(double x, double y): Returns the 2D noise value $(D -1,1) at the given position.
getNoise2dv double getNoise2dv(Vector2 pos): Returns the 2D noise value $(D -1,1) at the given position.
getNoise3d double getNoise3d(double x, double y, double z): Returns the 3D noise value $(D -1,1) at the given position.
getNoise3dv double getNoise3dv(Vector3 pos): Returns the 3D noise value $(D -1,1) at the given position.
getNoise4d double getNoise4d(double x, double y, double z, double w): Returns the 4D noise value $(D -1,1) at the given position.
getOctaves long getOctaves()
getPeriod double getPeriod()
getPersistence double getPersistence()
getSeamlessImage Ref!Image getSeamlessImage(long size): Generate a tileable noise image, based on the current noise parameters. Generated seamless images are always square (size x size).
getSeed long getSeed()
opAssign OpenSimplexNoise opAssign(T n): Undocumented in source. Be warned that the author may not have intended to support it.
opEquals bool opEquals(OpenSimplexNoise other): Undocumented in source. Be warned that the author may not have intended to support it.
opEquals bool opEquals(typeof(null) n): Undocumented in source. Be warned that the author may not have intended to support it.
setLacunarity void setLacunarity(double lacunarity)
setOctaves void setOctaves(long octave_count)
setPeriod void setPeriod(double period)
setPersistence void setPersistence(double persistence)
setSeed void setSeed(long seed)

Properties

lacunarity double lacunarity [@property setter]: Difference in period between octaves.
lacunarity double lacunarity [@property getter]: Difference in period between octaves.
octaves long octaves [@property getter]
long octaves [@property setter]: Number of OpenSimplex noise layers that are sampled to get the fractal noise.
period double period [@property getter]
double period [@property setter]: Period of the base octave. A lower period results in a higher-frequency noise (more value changes across the same distance).
persistence double persistence [@property getter]
double persistence [@property setter]: Contribution factor of the different octaves. A persistence 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 long seed [@property getter]
long seed [@property setter]: Seed used to generate random values, different seeds will generate different noise maps.
